I wouldn't go for any preamplifier, I would have a decent integrated any day of the week. Let's face it, pre/powers use up more space on the rack, you need an extra cable and integrated s sound better. Also, they produce less noise, winner, winner, chicken dinner! 👍

[@riccitone]

@@martinbishop2966 you’ve actually got that backwards. Shoving pre and power into one box tends to increase the possibility of noise. Noise is not an issue with good separates. Even these days, you’ll need to pay a lot more for a single integrated amp that can achieve the level of refinement and s/q of decent separates, even if simply due to layout design and isolation.

[@farrnick]

Thank you Harley, another masterful performance. I am thoroughly enjoying the Lyngdorf you recommended for me, it is so usable and a great interface to the rest of the system. I too am looking forward to your review of the Pearl Acoustics 170, single ended, vacuum tube power amplifier.

Me too @Farmick. I have the tdai 1120 with Q Acoustics concept 50 speakers. I'd like to get a tube power amp and use the Lyngdorf as a streamer/preamp when money allows - always wanted to try that tube sound. I got the Lyngdorf after viewing Harleys earlier review also.

[@manitoublack]

great conclusions Harley and I couldn't agree more. I've got a modest system (GASP: using an Onkyo RZ-50 AVR as the audio hub,) my wife and I just love having music in the home. So much so, that if we're home, there's almost certainty music playing. It's unlikely that I'll ever be investing in separates, because I have no intention of keeping up with the Jones's and cannot justify sacrificing a room in the home to a dedicated listening room. I love the sound I've got, It brings life and warmth to the home; but most of all we all listen to it every day. It's great to listen to a true student of the game give their honest opinion. Keep up the good work.

I don't have a fortune to spend on audio, so my whole setup is either DIY or preowned .

A couple of weeks ago, I purchased an Emotive audio [ NOT EMOTIVA] Sira preamp built in 2004 that retailed for $4800. It has since been upgraded the the best V Caps and VH audio silver input wires. It operates with 18 tubes. It's a beautiful piece of equipment. You can still buy them new, as they are built to order in upstate PA. for around $8000. I can't even begin to describe the improvement in the sound. Much more holographic image in the soundstage, and hearing more decay at the end of a guitar note. This preamp has got me to a place that has me completely satisfied with my system. Now all I have to do is listen.

[@AdiMaco]

This is a wonderful and informative review/podcast. It was a real pleasure to listen to your voice. Now, let's get technical: These preamplifiers, integrated amplifiers, and power amplifiers are, in fact, trans-impedance devices. They usually convert a high impedance/low voltage/current from the input to a low impedance/high voltage/current to the output. Ideally is to have high impedance input and low impedance output. There is a problem with passive preamplifiers, they usually have the same input and output impedance and this is the impedance of the device, the potentiometer. This gives us a very high output impedance that can not accommodate the high impedance of the power amplifier. Usually, this impedance is 10 Kohm to 50 Kohm which is very high (unless the designer uses output transformers to lower the output impedance). Hattor Audio doesn't tell us the input and output impedance for their passive preamps. Topping Pre 90 only tells us the output impedance which is a good low figure, 20 Ohm. Artera: input 10 Kohm line (SE and XLR), output: 120 Ohm SE, 100 XLR-this is not bad, these are good, but not very low figures. Elector SPL, input: 47 Kohm SE, 20 XLR, output: 75 Ohm (SE and XLR). The input impedance is good to very good and the output impedance is also good, but considering this is a pro audio company they should have made it with a lower impedance, like Topping. Musical Fidelity M8S pre has very good figures, input impedance is 75 Kohm SE (RCA) and 150 Kohm XLR, and also good, low output impedance: 47 Ohm RCA/XLR. Michi P5S2, input impedance: 47 Kohm RCA, 100 Kohm XLR. Output impedance: 470 Ohm RCA, 100 Ohm XLR. Michi has good input impedance but the output impedance is rather high. Sugden Audio Sapphire DAP-800. Unfortunately, Sugden does not tell us the input and output impedances. PSAudio BHK, input impedance is 33kohm RCA/66kohm XLR. Output impedance: under 100ohm. The output impedance of PSAudio BHK is very good, but the input impedance is not very high. Pass Labs XP-12 has published only the input impedance which is not very high, 22 Kohm. Mola Mola, the input impedance is 100 Kohm, which is very good, but the output is rather high at 440 Ohm. It is very important that the impedance of the power amplifier is high and at least many times (100 times higher) higher than the output impedance of the preamplifier. Mola Mola boasts that their preamp has low output impedance and that the audio output is not influenced by the type of interconnect, which is not accurate. The advantage of a low impedance is that longer interconnect lengths can be used, as with balanced (XLR) connections. Low-output impedance preamps like the Topping Pre90, ElectorSPL, Musical Fidelity M8s, and PSAudio BHK are more likely to sound good with a wider variety of power amps than high-output impedance preamps.

[@prutser132]

For me, this is very helpful. This past summer, I acquired a tube power amplifier with 2 x 18 watts of power, weighing nearly 40 kg. It was handcrafted by a musician and completely overhauled for sale, including new tubes and many Mundorf caps. Since I’m on a tight budget, it was quite an expense, but still an absolute bargain. This amplifier is truly a dream. It sounds fantastic with my old KEF RDM-2 speakers. I also have a pair of B&O RL140 speakers in the shed that I plan to refurbish. I’m curious to hear how they’ll sound with this setup. A while ago, I started looking for a preamplifier because I came into a windfall of a few hundred euros. Not the smartest idea, as I should have saved that for something really high-quality. Anyway, I found an Audiolab M-DAC+ with an issue. It’s a DAC that also functions as a preamplifier. The problem was said to be that the DAC would sometimes sound tinny and compressed upon startup, an issue that could be fixed by briefly switching the filter. For the price, I thought it was worth the risk. So far, I haven’t experienced that problem. And wow, the sound quality is incredible compared to the pre-out of my old Superscope amplifier. The KEF speakers are truly coming alive on their stands and sound amazing. The sound quality is actually approaching that of the very expensive Conrad Johnson preamplifier owned by the seller. What I love about this audio hobby is that even with a very limited budget, you can still achieve great results. The seller mentioned that this power amplifier isn’t really suitable for passive preamplifiers.

[@spvlinn9009]

Great review Harley! My own experience is that when everything else is pretty much there, your wire with gain becomes very very important. For example I am more than happy for last bit of performance for less look or lack of a remote. You kind of hint that with that 600 euro topping, you really don’t lose anything even in absolute term. I always believe is that you just cannot build a first class preamp without a very good power supply. I wonder what kind of ps they use for such a small and light box?

[@PearlAcoustics]

Thanks for your very kind appreciation. 🙏 you raise a good point about power supplies, whatever Topping use, it certainly works. It gets a little warm in operation but not hot. I guess it’s switching…

Thank you for the comparison on these pre amps. I use a Vitus Class A integrated, fell in love with the smooth Class A sound ever since owning a Sugden A21A. At times of course I ask myself if a pre / power combo would improve things further… I am very surprised though regarding your statement that the Topping side by side performs pretty much on the same level than the Mola Mola. Knowing that the pre can play such an important part in a premium set up. If the $600 Topping can play at a level of a $10k pre than I would just use the pre amp in a decent DAC? Would be great if you could elaborate further. Thanks again for your time producing content on YT - loved the the Kid A episode!

[@PearlAcoustics]

Hi, thank you for your very kind comments. I am so glad you enjoyed the Kid A video. To answer your question on quality and price differences. When one goes into industrial design and manufacturing, there is always an investment in research and development, that at some point needs to be paid back. The team involved have to decide how much they expect to be paid for it. This can range from nothing, for a retired engineer, to a fortune for someone who dreams of the high life and driving around in expensive cars. (I am not saying this is the case in either example I give). All is possible, but you have to decide. Taking the Topping versus Mola Mola story, Mola Mola is about perfection, being the absolute best. They started with a blank sheet of paper, after studying how everyone else across the decades solved the challenges posed. Once their design is finished, They manufacture in very small quantities and all their components cost them much more than their volume production competitors. Making a chassis like theirs is probably their biggest single cost. Everything is in very small quantities. And hand built in the Netherlands. Topping on the other hand, set out to design and build the very best sounding preamplifier possible. They came up with absolutely no compromise design (sound wise), but from the start they are thinking in miniaturisation and container loads of products. If you can make a component smaller, without impacting performance, you save on material costs, casings, packaging, shipping, etc etc. Every square inch or millimeter saved makes a big difference in the final equation. They are looking to develop chassis, circuit board, power supplies and components that can be used across a multiple of devices and even brands. But always with a ‘no compromise on sound quality’ as a goal. They are out to beat the best and keep products cheap, and small so they can sell to everyone. Then they sell direct, or via on line retailers that take the tiniest Olof margins. A typical high-end retailer will want at least a tines 2 mark up. Then the distributor needs their 20-30% margin. Add all this together and you very quickly arrive at the high prices we see. The retailers need their margins. Buying up front, taking risks, owning large expensive showrooms with staff to pay, costs a fortune. So the Topping is fantastic value. But it does not have the charm or streamlined operation in its user interface. It has no software application that needs constant upgrading. It also has its limitations (like its remote control) - but adapting that would cost them a fortune… because of the numbers involved. I hope this makes some sense? Enjoy the music

[@thomaswomack3888]

I really appreciate your presentation and opinions. I wish my budget allowed indulging in some of the high end gear you present, but frankly the Topping preamp would be considered a luxury. Nevertheless, its so good to see you compare these preamps with such a disparity in cost in such a practical way. I will most likely get a topping in the near future due to your review in spite of the bad remote. This will end up being used as a desktop preamp where the remote is perhaps less important. I would love to hear about your speakers and what advantages you find in such small drivers in such large cabinets.

Charming as we've come to expect Mr. Lovegrove. My question: Why dont most preamps have a balance control? An essential feature for those of us with asymmetric room layouts. Wouldn't it be easy to implement with relay based volume control? Im enjoying my Musical Paradise MP701mk2 tube and capacitor rolling preamp. Check out Thomas' recent review: "Five+ preamps in one" I use the input trim pots on my Bryston amp to provide balance control;-) The Topping pre is tempting so i can use balanced outs from my Ares12th... 🎵🎶🤫🎶🎵

[@PearlAcoustics]

Thanks for your kind words. You raise a good question. Balance controls became conveniently ’out of fashion’ as a purity argument / which obviously also reduced costs. In a way, this is what my video alluded to - choosing a pre amplifier is not all about purist sound quality. That’s why I brought in the Lyngdorf because you can program balance etc, all in the digital domain. For Topping to add balance would be complex as they have already squeezed so much into their little box. Your solution seems to work for you but indeed, the balance control is so useful. The QUAD Artera Pre has a very nice set of controls, balance, bass, treble and their famous ‘tilt’ system. It’s a marvellous preamplifier and extremely good value for money as it is also beautifully made.

[@carlitomelon4610]

Hi thank you for your kind comment. Unless you are employing an additional preamplifier to process the incoming signal in some way (for example, room perfect), I am not sure I see the point of adding more components and complexity to the chain. The Sugden A21SE is a very fine integrated amplifier with its own sound signature in its own right. But, like all things hifi, it can be great fun experimenting.

[@chrissimmonds4383]

Excellent comparison of preamps. I have the Quad Artera Pre which is a really great preamp, sonically. It's also very quiet with a lot of gain and each of the relay selectable inputs the gain can be altered to match the other inputs. The only downside is the very necessary remote as to change settings on the preamp itself is a pain. The remote's control for volume is also critical as when pressing volume -, it's easy to change inputs. I've had two so far and the latest one is getting a bit flakey. The performance of the preamp can't be faulted imo, even the phono input is excellent.

Excellent video. Most of my amps are integrated, but recently I have been experimenting with vintage gear, and picked up a Sansui Ba-F1 power amp. A massive beast of a thing. I am using a Sansui AU7700 integrated as a preamp, and am astonished by the versatility built in in the 70s. Firstly the ability to completely disconnect the pre from the power amp sections. Secondly bass, treble and mid-range adjustment with low pass and high pass filters, and a bunch of other options. Lots of inputs including twin phono inputs as well. I think we have lost something in the last 50 years, and perhaps that audiophile obsession with simplicity and a straight wire with gain is misplaced.

I chose an Artera, which I'm very happy with. I bought it because it was the most affordable high quality pre' with balanced outputs that I could find. I'm a musician and have a modest laptop-based home recording set up. I bought the small PMC powered monitors to use with it and found I preferred them to my ageing hi-fi speakers. Rather than replace them, I decided to use the PMCs for listening and looked for a pre' that would drive them. Did some digging and came across the Quad. It was on special offer for under £1k, which was a bonus. The smooth and slightly gentle sound of the Quad means it works very nicely with the more forthright presentation from the monitors. At under £3.5k for amplification and speakers, I don't think I could do much better for the money.

You make a great point about the combination of the power amplifier and the speaker. I have reached a great pairing that works and just like you I am experimenting with preamplifiers. A good preamp makes a signal come to life. Bad ones eat detail and editorialise. When a preamp retains the details such as coherent ambiance, expression, inflections, timing and imaging without colourations, noise or distortion I sit up and enjoy the music. Couple those criteria with bandwidth and effortless dynamics and I just love to listen. Beyond that the mechanics, the user interface and the ergonomics have to be tolerable.

[@peterlarkin762]

As an avid DIY'er, preamps are possibly the hardest piece of gear to get right in terms of system matching and neutrality. Some thoughts: There's no excuse for a preamp with a high noise floor - that's not a price issue, it's a lazy engineer issue. Impedance matching: input impedance should be >10x the source output impedance. Output impedance should be at least 10 times less than the power amps input impedance. This is often overlooked. Check the specs before buying, especially when mixing valve and solid state gear. Gain is good, until it's not: A lot of preamps offer huge gain and you end up using only a 3rd of your volume control travel which means you loose resolution and attenuation 'sweet spot'. Tone Control! Please don't be offended but my room is not perfect, and I listen to a range of genres with varying recording quality... I tried DSP and found it was not ideal for sound quality. A well designed tone control circuit that can be completely disabled is a beautiful thing.

I'm currently hunting for preamp. The Elector caught my attention but I read that it has VERY low gain and needs to be carefully matched. The Artera also looks interesting but haven't heard Quad gear since the grey and orange days when I found it to be rather soft in the bass. At the time I owned mostly Threshold gear so I suppose I was spoiled. A used SL-10 like the one I owned is still selling for about $1500 44 years later, in very average condition I must say. It must have been as good as I remember it.

[@afonsomiguelcorreia]

You missed explaining why you need a pre amplifier. I’m starting my first music system, and using as speakers the monitor audio gold gs60, and the sugden a21SE. For what I can understand the amp is more the. Enough to drive the speakers, do I need a pre-amp? Thank you for the amazing work

[@PearlAcoustics]

Hi, thank you for your question and very kind appreciation. Fundamentally, there are two kinds of amplifier a pre-amplifier (where the incoming information is either amplified from quiet to loud, or ‘attenuated’ from loud to quiet. Once we have set the volume the signal is sent to the power amplifier that amplifies the signal enough to drive the loudspeaker. The power amplifier has no attenuation, it just amplifies what comes in to it. Your Sugden A21SE is what we call an integrated amplifier, where the preamplifier and power amplifier are integrated into the same chassis. This is mostly done for convenience. However, the preamplifier (in the old days referred to as a ‘control unit’) usually has additional features like being able to switch between multiple inputs and sometimes bass and treble controls and even a headphone socket. These are the ‘features’ that I refer to in the video which can vary over time and can necessitate us changing our integrated amplifiers, while in all other circumstances, we are totally happy the the power amplifier section of our integrated amplifier. (I hope I am explaining this clearly). In short, you do not need a pre amplifier for your Sugden as it has one built in. However, if you want to connect a record player, you will need a little external amplifier that you would put between your Sugden and your turntable, similarly, if you wanted to connect headphones or shape the sound in anyway then you might find you need to add other components (including a streamer). I hope I have answered your question? Enjoy your hifi, I am sure it sounds wonderful

[@afonsomiguelcorreia]

@@PearlAcoustics thank you so much for this precious information. I have a rega turntable (p10, following your best advice :)) with the pre-phono and will soon add a streamer (probably the Eversolo A6 master edition/A8). For the streamer do you think I need to add any kind of pre amplification? Best regards

[@PearlAcoustics]

@@afonsomiguelcorreia you’re very welcome. No, your Eversolo will plug straight into your Sugden. You’ll have a lovely system then.

[@cosmiccharlie8294]

I have been enjoying my Emotiva PT2 pre. Great functionality. The built in dac and phono stage could been left out because they are sub par. I really like the high pass on the mains out and also the low pass sub out. And the FM tuner is a must have for me (classical music).It plays nicely with my diy Pass ACA.

[@PearlAcoustics]

Thanks for your comment. The Emotiva has a lot of features for such a reasonably priced piece of equipment

[@jdm-uk-yank]

The Sugden Headmaster makes for a fantastic preamp. I originally bought it just to use as a headphone amp. But, when I bought some Monarchy Audio monoblocks I need a pre. It was going to be temporary but I've no need to change. Remote and three inputs.

[@PearlAcoustics]

Sounds perfect

[@Gez492]

[@PearlAcoustics]

[@jamesj590]

Musical Fidelity is still for me the best bang for the buck I've encountered. I have that pre in my setup. Some say it's a hard edged sound, but I've never felt that way about it. Running Confidence C1 and C4 platinums and I find the pairing hard to beat.

[@PearlAcoustics]

Indeed, I never found it hard either. If anything, I found it to be on the ‘warm’ side of neutral.

[@rasardo1]

Another excelent video. Luckily, I have no intention to buy another preamp, because I've bought mine, second-hand ,for an excelent price (new is about 5500 Eur). The preamp is the german Audio Exklusive P7S (dual mono, two separated transformers, 100% equiped with NOS tubes) and it allows to select the gain and the feedback. It sounds terrific, and for the price, it's the best I've heard so far. You've mentioned in this video that that Sugden preamp is equiped with an old Philips DAC. I've got 5 CD players at home, with different DAC chips, the majority multibit, Marantz CD40 and Marantz CD80 (TDA1541A), Revox B225 (dual TDA1540), Primare CD31 (4xPCM1704-K) and one equiped with the dCS Ring DAC (Arcam FMJ CD23T). My best sounding CD is the oldest one, the Revox B225, from 1983, with the best CD transport ever built, the CDM-0. It was been fully upgraded, with excelent capacitors, operating now in NOS mode, replaced the plastic TDA 1540 chips for the ceramic ones and other few things that elevated, even more, the very good level of the original unit. The Revox, is my reference player, because I don't know any other player around, new or old, (cost no object) that sounds even close to this superb player. Is the most analog sounding player avaiable, with the most credible and incredible midrange, that sends shivers down your spine digs every bit down to the smallest detail. I invite you to buy one (or listen to one) and try it for yourself, even without the upgrades, that I truly recommend.

[@Metranger-xd4bt]

@@PearlAcoustics Everyone says the same thing about Max. And he is sorely missed....I corresponded with Max who told me that except for very long distances, he preferred RCA's(had more "pure sound") to XLR's due to the added circuitry in XLR's. Controversial perhaps but he was steadfast in his belief.

[@PearlAcoustics]

@@Metranger-xd4bt Max was 100% correct about RCA over XLR but only if the equipment’s design was single ended. Because in that case an extra transformer or other array is needed. However, IF the design was balanced from input to output then that was not the case. But most hifi equipment is not fully balanced in design. XLR was originally used in broadcast studio conditions to help avoid interference from studio lighting.

[@Metranger-xd4bt]

@@PearlAcoustics Ah! Well that explains it then as Max's Allegri Preamp is not true balanced. It is pseudo balanced as he wanted to avoid a much larger device with extra "apparatus" that could create noise. Thus single ended is preferred. Still a great preamp. Hopefully 1 day you can give it an evaluation....Thanks!

As an audio equipment seller (import and retail) I used the Sugden LA-4 preamplifier for over a year, daily, with various power amplifiers, including monoblocks from PassLabs and Audio Reasearch. The LA-4 is a universal and very musical but also dynamic preamplifier. They sound, in my opinion, even better than the $10,000-$35,000 preamps from PassLabs. Sugden saves music from technology. Nelson Pass is a genius in audio electronics, but his preamplifiers are over-engineered and they sound a bit artificial, in my opinion, as well as his integrated and power amplifiers.

You did it again! Great video. Very last point about enjoying the music is truly paramount. -- I would have liked a bit more focus on pure pre-amps, i.e., without built-in phono-stage and/or DAC. It also seems that the most significant difference between preamps is tonal coloration and detail, but sound stage is implicitly (by lack of mention) the same. Interesting. I am more of a sound-stage person, and I think that is nothing that the ear can get used to, while tonal balance can be EQ-ed mentally to a degree.

[@PearlAcoustics]

Thank you very much for your kind words. You’re absolutely correct, the absence of me mentioning ‘soundstage’ is a big oversight. I am with you in this. Although I really want purity, transparency, above all I want a nice wide soundstage. All the instruments clearly separated. I tend to feel that this is mostly controlled by the power amplifier (it either has it, or it doesn’t) but you’re 100% correct.

Harley - strictly speaking as a line stage only excluding their built in DACs, on SQ alone and a cost no object opinion, would you choose the Sugden DAP-800 or Mola Mola Makua when pairing to Sugden power amplification?

No question - Mola Mola. Because it’s a bit cleaner in sound, quieter, is very well built and I much prefer the remote control and other possibilities. But it is very expensive. The Dap-800 is good, don’t get me wrong, but its sound is slightly warmer. So it really depends on your preference. You really need to try both first, if at all possible.

Hi, if truth be told, I have not done a true side by side comparison. But I have heard both and used both. They are very different pieces of equipment. The xp-22 being a pure pre-amplifier with separate power supply, with much more functionality from the remote control. + build quality is fantastic. So if you have a really satisfying Dac already, then the Pass would be my preference - the performance is superb. But, if you’re looking for a very musical Dac and a pre, then the Sugden is very good value for money. If you don’t mind getting out of your chair to change inputs. I hope that helps?

[@PearlAcoustics]

Thanks for your very kind words. Indeed, sound quality and soundstage are vital, I think the point I was trying to make is to define ones practical needs first and work backwards from there. For example, if you don’t mind getting out of your chair to change the input selector, then you have a long list of comparisons. I tried to touch on sound quality a bit but comparing with ten became too complex. Too many variables. In theory, the pre should be transparent - but often they are not. That’s why I liked the Topping, the SPL, Sugden and the Mola Mola. I think some manufacturers make the pre too complex. A great pre should not interfere with soundstage and should not add colouration.

[@PearlAcoustics]

Not a silly question at all. Indeed, there are so many variables when it comes to build a hifi system. If you decide to go down the route of preamplifier / power amplifier combination… you will need to choose the preamplifier first, (with the functionality you want) or use the ‘pre out’ of an integrated amplifier. And compare power amplifiers that way. I hope that helps a bit?

Are there any differences between the Elector and the Phonitor X with regards to the quality of their speaker output? I do not want to lose the ability to use headphones in my system (and currently do not have a separate headphone amplifier) and the Elector does not have a headphone output. I know the Elector has more balanced and RCA inputs, but for my needs the two inputs in the Phonitor X (RCA for my Rega Saturn Mk3 and balanced for my Technics SL-1200GR via a Gold Note PH-10) are enough.

Hi Harley, thankyou for a really nice review. I own the MF 8s pre and pwr which I really have enjoyed. I am always hearing about valve amps and have resisted them up until now. I recently bought a second hand oldish Prima Luna integrated amp to finally see if there is a difference. Not sure if you have heard the Prima Luna products (assembled in China) but I cannot believe the sound this amp produces. Running through the Focals (with the beryllium tweeter) you literally cannot stay awake it is that smooth and involving. It some ways it makes me sad as the MF's are really nice but how do you go back? warm regards as always from New Zealand.

Hi Russell, thanks for your kind appreciation. Absolutely, I HD e heard if Prima Luna. They are extraordinarily good value for money. I think one has to be a bit careful about generalising when it comes to tube amplifiers, I have heard some awful ones too (even from big brands). I find the M8 power amplifier to be particularly good, so just for fun, you might want to try your Premaluna as a preamplifier into the M8, if it has a variable pre output? If you like tubes, then do consider trying a pure class A tube amplifier too or even a Sugden A21SE or SPA4. When do you go back? When it’s full Summer and you don’t want a heater of an amplifier making your room even hotter! 😀 Enjoy the music, Best wishes Harley

@@PearlAcoustics Yes, IT IS a DAC, Headphones Amplier, a PreAmp, Equalizer and so on. As far as I know even compatible with SACD Players. Abmulti purpose Tool so to say. You could dedicate a whole video to this piece😀

Thank you too!

Ive had the Quad Artea pre and power amps for a couple of years. Battle ship build and sounds superb. A bargain at the price and will probably outlast me.

Indeed!

If I were asked what *one* component in my system I would not give up it would be really, really difficult to pick just one. The contest would be between my Lab12 Pre 1 preamp and the DECware “Zen amp” SE84UFO. The Zen is just SO good, especially since I did some tube rolling and settled on a set that I think (so far!) is optimal. That said, even with speakers with sensitivity of 90 dB, the little Zen can be challenged with some recording and volume levels. Aside from great reviews that’s one reason I bought the Lab 12 preamp. It has gobs of gain, besides being a clean and “pure” component. So overall if forced I’d say the Pre 1 would be my choice. Not that it is much good without the other components!

Currently my system has both Pass XP-15 phono and XP-22 linestage preamps.They pair very well with my Audio Research VT-100 Mk III amplifier. I have regrets about selling some of my former preamps, especially my Audio Research D-76A, my Mark Levinson ML-1 and especially my Audible Illusions Modulus 3B for its simplicity of design.

Thanks for sharing! You’ve certainly had / have some very high-end equipment. Enjoy the music.

My PRE90 sits across from me in its stack and I’ve never had a problem using the remote. It could be better, like the Appletv’s that works in any direction, but it is quite functional. It’s definitely point and shoot but it’s good enough for me. It has boosted the dynamic range and clarity of sound, probably better impedance matching. Keep the batteries fresh!
