When I was a teen in the early 80's, I bought an Emerson floor model record player off an elderly couple. It was a small box with two 12" speakers,and two 5" tweeters. It was incredibly efficient in size. The speakers were placed diagonally on a small board in the front. Above the speakers was three knobs, Volume, treble, bass, mounted on a gold colored slat of aluminum. There was a Voice of music turntable inside, with a PowerPoint crystal cartridge. The amp had four tubes, an 5Y3 rectifier, an 12ax7 driver,preamp and two push/ pull 6v6's. There were small screw on legs, as was the style in 1957, the year of manufacture. The sound was incredible!!! Monaural one channel, and blaring hi fi . Full rich tones at every frequency. I took it to a huge dance hall were my cousin was having her wedding reception. A DJ wanted like 750 bucks, I was an avid record collector, and had plenty of records. There was a concern that this little box that sat on four 6" inch legs, wouldn't be loud enough to fill the huge hall with enough sound to override all the noise, and talking, for dancing. It turned out it was too much!!! People on the opposite side of the wall asked if it could be turned down a bit, the vibrations were reverberating, and people couldn't hear each other talk. I have had many different systems since then, but nothing can surpass the charm, of the sound that, that small record player created. It was destroyed eventually by a family member's stupidity, and negligence....sigh!!! Been looking for another ever since.

I grew up with vacuum tube audio. Grundig and brands of that era. Had always loved the sound. Then I joined a band. The amps were all tubes. It had that special sound. Can't explain it. Later on came solid state. I had a few sold and gave away a few. Not terribly expensive ones. Last year I met an old friend who is a wizard with electronics. I showed him a DIY kit and asked him if he can improve in it. So I bought the kit he took it and after a month or so brought it back to me. It was a cheap preamp. I have a solid state power amp set it up with my wharfedales and am I a very happy man! It sounded realistic. Dynamic. Voices are clear and superb. My friend had done his magic. Changed most of the insides to top of the line things. I don't know what they are. So I'm happy.

I've been into Hi-Fi for more than 40 years and favorite sound is the tube sound or the tube/solid-state combo. There are some solid state units that are holographic in sound but they do come at a price. Companies designing solid state amps that employ mirror distortion correction and other special circuits is a step in the right direction [Electrocompaniet, Hagel, Lavardin, etc.] and I hope that that technology continues to the point where solid state equals and surpasses the classic tube sound. An amplifier in the $1500-$3000 range is very doable using good and or premium parts, believe me! Thomas, don't worry about trying to describe aspects of sound-it is not easy to do. If you think you are being redundant, don't worry about it- that's fine and somtimes repeating something is done for emphasis to drive home a point. I thought Thomas did a fine job painting word pictures describing sound. THOMAS -keep up the good work!

Interesting review Thomas, thanks. You definitely hit on the biggest reason I prefer tube amplification which is the effect on sound stage size and shape- e.g. typically much larger in all directions and more spatially enveloping and interesting musically than solid state amplification. When I listen the vocals and instruments seem to be coming from a defined position with gradually diminishing edges. The positioning is easily noticed but the tapering off of the boundary is very smooth which makes the image much larger. Another huge reason (for me) is the ability to tune using different tubes. I have found that we can tune virtually any sonic parameter using different brands of (usually NOS) tubes, including smoothness, sound stage, tonal balance and transparency. I usually limit tube changes to the smaller signal tubes and not power tubes. This is where you find the tube "smoothness", through quality NOS tubes. I have also found that tube "effects" are maximized using a tube integrated amplifier or tube preamp / power amp. With even the best tube preamp / solid state power amp I have heard, the soundstage seems collapsed vs. a full tube amplification system. Unfortunately there are limits as you have noticed, and even the most powerful tube power amps cannot compete with the power, room size capability and grip of better solid state amps. Using tube monoblocks doesn't get their without some compromises either. For me the combination of a solid tube integrated amp using KT120 tubes (100 WPC) and a semi nearfield setup (e.g. 9 feet from speakers) with moderate efficiency speakers (86db) gives me the best of all worlds. Try a Rogue Audio RP5 preamplifier and Stereo 100 Power Amplifier if you ever have the chance. Sounds better than most everything out there regardless of price.... Peace and all the best. -Tony

I have a The Fisher 80T Hi Fi mono preamp and AM/FM tuner manufactured in 1958. In addition to independent bass and treble controls, it also has a 4 level loudness control. It also has an RIAA phono input. I listen to mono jazz and blues records with it and the quality is impressive. No noise in the background, and you have all the bass and treble you want. You can have a more rounded bass or harder. You can have very loud treble or just the timbre of instruments and voices. And the sound is definitely warmer. It also sounds great on FM and specially AM, which you can choose between wide band tuning that provides audio quality quite as good as FM or "sharp" with narrow band and the sound is pretty much what we have experienced when listening to AM. I also have a The Fisher 55A tube hi fi mono power amplifier, but the 80T preamp works so well with stereo my solid state equipment, I don't know if I'll have a use for it. For stereo records, I use a Cambridge Audio pre-amp that I enjoy very much. I also have a 1962 Heathkit tube stereo integraded amp. It has both ceramic and magnetic cartridge preamp inputs. It is being restored and I asked the technician to install a preamp lineout so I can try it with my stereo records. Let's see what'll come out of it. But one thing I noticed from the start: my mono jazz and blues records sound so much better with this tube preamp. Not so much for stereo records, since some instruments almost disappear when blended together in a single channel.

I've always liked tubes in the front end, meaning pre-amplification. I prefer solid-state for the power amplifier. Tubes require (SET's of course are the exception) an impedance matching transformer to drive the lower impedance speakers in a power amplifier. The challenge for manufactures is to minimize the hysteresis loss in a output transformer. The whole of a coil of wire wrapped around a metal core is the basis for an inductor, and inductors oppose rapid change. That's where the earlier big names in the audio business were challenged to produce clean treble tones past 15KHz. As products evolved, bandwidth improved, but in my earlier (better ears) days, a tube amp suffered in dealing with quick transients. Transistor amplifiers were able to use push-pull technology without the need for an output transformer, unlike tubes. Now these are generalizations, subject to the craftsmanship of the engineers and manufacturing. All things not being equal, no matter the money spent, an expensive product isn't a guarantee for better sound. I've been involved with the repair aspects of pro-audio and higher end equipment. I can usually look over a schematic, then inside the product and predict with reasonable accuracy, whether that piece of equipment is going to sound good, or not. I've heard differences in tube from solid-state for decades. For example, I owned and used various open reel tape equipment, and for my ears, the Ampex & Roberts tube tape decks sounded so much better than any solid state products. That included their later incarnations, as well as Studer-Revox & Crown. Later solid-state improvements closed the gap, but the holographic sound you described was evident all the way backs to the '60's. I would very much like to get the opportunity to listen to the latest B&K amplifiers that are offered through PS Audio. He combines a tube front end with a solid state output. They cost is too much for me, now that I'm retired. I've also been tempted to buy a kit from Pass Labs, for the sake of finding out if there's real magic in those designs.

We can design a complete amplifier in solid state performing the same if required but for the same money we can have a much better amplifier SS and do not need an output transformer. Tubes amplifiers are just for those nostalgic guitar players , nothing to do with the excellence of sound reproduction, and the quality of sound they claim to have with tubes, just pure and simple personal choice that turns into a cult to give more business to other countries still producing tubes in their old machinery.

Hi Thomas, I am in Australia and I enjoy your videos very much. I have tried lots of different SS receivers and like them very much. I meet a guy online here in Australia who built tube amps for many years and then he had an idea for a new style amp that does not use a circuit board and he said it was far superior to tube amps. I decided to buy one of his new amps and to my surprise the amp is every bit as good as he said it was and more. The clarity is outstanding and very neutral and rated at 30 watts but seems more like 60-70 watts, sorry I do not know the specs of the amp but I go more on the sound rather than what is written on paper. I am impressed with what I am hearing, on some recordings you can hear the artist breathing into the mic before the music begins. This guy only builds amps to order, he does not have a shop or website and he is an older gentleman, I am very glad to be a proud owner of his amp and I am looking into getting him to build another amp in the near future. I currently own around 20 SS receivers and I do not listen to any of them anymore because his amp is far superior and I own flagship model from Akai & Luxman and now I will sell them along with other rare models. I have this new amp playing through IMF-RSPM speakers and the sound is out of this world, no more buying gear for me as I am very very very happy with this setup.

I will look at the video you suggested, by the way the amp I brought from him earlier this year was only $700 [US $480] and now he has designed a new amp rated at 55 watts. This guy is a genius and builds his amps in his kitchen as he lives in a very small house with his wife. I have posted below a small write up that I found on the internet about one of the amps called "Quasimodo" in this write is says he uses mosfets in the output stage but in his new design he has moved away from this --:
@lorindamikaela6 жыл бұрын
from the internet --: The Quasimodo amplifier is the result of some 15 years of development to make a stereo amplifier that sounds as musically enjoyable as possible. With no circuit boards whatsoever, all the components are hard- wired on tag strips, which really does help the sonics! The 40 watt model, for instance, is rated at 40 watts per channel into 8 ohms and around 70 into 4. There are also 25 watt and 80 watt models. They have been" voiced" to closely emulate that of a good valve amp. This has been done by ensuring that any distortion artefacts are primarily even - order, with 2nd order dominating, followed by a very tiny amount of 3rd, after which 4th order is higher in level than the 3rd- and so on in gradually reducing order. According to the SPICE program, the distortion at normal levels is about 0.063% with the "nice" sounding 2nd order artefact dominating- just like a good valve amp! A transistor amp that has been designed with a perfectly symmetrical circuit configuration will ALWAYS generate primarily odd order distortion artefacts and will sound, well, "transistor- ey" The Quasimodo deliberately uses a somewhat asymmetrical transistor / mosfet output stage to ensure that any small distortion artefacts are going to be the harmonious even order types. Subjectively, an amp that has a distortion figure of say, 0.5% 2nd order dominant , will always sound far more "musical" than one rated at 0.03% 5th order dominant! 5th order distortion is subjectively quite nasty sounding, so it is good practice, I have found, to ensure that even order dominates, thus "masking out" the nasties! The Quasimodo amp is inherently safe, and even in the highly unlikely event of an output stage failure, no harm can be done to your precious speakers! This amp sounds so good, I have now stopped building valve amps, of which I have four now just gathering dust! After hearing the Quasimodo, I think no other amp will quite sound as "right" - at least that's what I have found!

Its been great for mobile and localized listening as well as putting out in the garage. Very versatile when considering the size and the capability of the unit.

My opinion is just simple. I prefer Tubes in my Preamp, where they can last probably 10 times longer than in a Poweramp. The more Power a tube has to provide, the shorter is it`s overall life. And for Power Amps, I feel good with Solid-state Gear. This way I can gain the most advantages for me. I cannot live easy with the idea that I have to change my tubes once a year - and due to I am retired, my Audio system runs 24/7! (I also use my tube preamp to watch movies, not only for the music). Maybe I will try a tube power amp someday in the future, but there are a lot of other things before that on my list... That said, it is very inspiring to listen to Thomas` opinion about that case!

This sounds like a tube guitar amp discussion! I went down that road and have a great collection of tubes both power and input stage and spent thousands on guitar amp rigs "seeking the perfect tone." I still have a classic tube pre that I just cant seem to part with for my guitar but find I use a Digital Device for my guitar most of the time for amp tones. I am certain if you want to go nuts with your dedicated stereo room and system have at it. Personally I think it gets a bit too crazy and expensive. I would look for holographic speakers first like Omni Directional designed speakers vs front firing drivers. Then move into the insanity of electronics such as experimenting with a variety of tube pres. As per the power side not sold on the sound and expense of tube power for output. This was something I learned going through my seeking " the perfect tone" period as a guitar player and feel it can tie with home stereo as well.

For even more holographic soundstage I find a Directly Heated Triode [DHT] preamp is the way to go.I have been using a Supratek Cabernet 300B preamp for about 12 years and have compared it to a lot of other preamps many of which cost a lot more and none of them produce such a big open 3D soundstage.Coincident also make a very good DHT preamp which is made in Canada.The Supratek is Australian and made to order.

relatively well explained, but lacking knowledge of the basics of electronics. As a 40-year-old amplifier manufacturer, I can only say the following: the tube amplifiers are not HiFi because they colored the sound. Tube amplifiers are slow and have no dynamics. In recent years, the sophisticated High End has been just doing nostalgia for the past times. Tube amplifiers are good only for live playing as guitar amplifiers (for bass not). Wherever I was in the presentation of tube amplifiers, I always listened to the same songs (exclusively jazz). When I asked to play something of high-quality rock like Led Zeppelin, they mostly objected to the auditorium's not exactly about that type of music. But the truth is, the tube amplifiers show that they are a common disaster. The next is a bad frequency range for the audio transformer, because in order to get linearity at higher frequencies I had to use a very thin plate (0.1mm) in the core transformer because the problem through the transformer is to push 13Khz or more (curve hysteresis). So then something that is not capable of reproducing the whole audible range becomes HiFi. These are the facts. Hifi sound is pure sound, no color, no heat, and everything that the tube amplifiers have when they are working. The dynamics of the tube amplifier / transistor amplifier comparison is compared to the image rate of plasma TV and LCD TV. Tube amplifiers are just nostalgia and nothing more

Great discussion, Thomas. I think most audiophiles come to that crossroads and start to gravitate towards tubes for the reasons you pointed out. The way you explained the holographic sound describes a sound characterist I've always liked, but not I've not had someone describe it in those terms the way you did. I found myself going back to solid state, both amp and preamp, when I went back to listening good music for entertainment and relaxation purposes rather than critical details. In this, the warmness and weight of sound was more appealing to me. It seems that the only way to be satisfied is to have gear in both tubes and solid state and a collection of speakers to match. Thanks for your good reviews.

These include, imho, tfk ecc83 (both the ribbed and the smooth plates), new Russian Gold Lion ECC83 (gold pins), vintage Russian 6HN2-ev (substituting ecc83 with 6.3 v heaters to pins 4 and 5), and Sovtek ecc83lps and its varieties such as the EH ecc83. One mention deserves some attention would be the vintage Raytheon ECC8 of USA make. All others, really I can hardly tell the difference, withoutl intensive listening.

Those who prefer tube amps is OK as a personal choice, no problem, but saying that tubes are better than solid state is another thing. In my professional experience I had to adapt from several different kinds of tubes from many different makes and from different countries, so I can say a lot about tubes, the same happened with solid state. Yes, we can make marvellous amplifiers with tubes, I made some very good ones. There is no question about it I pass through it, design built test and compare performance. Ithrough the technologies of Radio receivers and transmitters, Radar several types, Electronics measurements and related instruments, Television American and European difference, fora LOT MORE MONEY, after that you can say whatever you want, is your choice, but it will not change the results of the tests and comparisions. In audio caption, recording, and reproduction there are much more than amplifiers (amplifiers are the least important unit in a sound insttalation) like Microphones, Loudspeakers, location of those and also most important is the Room acoustics. BUT ABOVE ALL IS THE KIND OF SOUND AND PERSONAL PREFERENCES. Whoever prefer a modern tube amplifier, is alright with me, but please do not tell about tubes what they are not, they had their time.

It might be the damn room, or his TT, bit I still think it is the combo of that pre and out with tubes and solid state. By the way, that thing is cheap, 10 times cheaper than my system, trust me.

I agree, it's all in the listening & i've also experienced how all tube pre-amps from reasonably affordable to very costly (i'm strictly trying to keep things relative to disposable incomes) ...can vary as much as transistor preamps do. Tubes do preamplifier duties best of all, i.m.o. & for technical reasons. Tubes are technically better suited than transistors are for low & line-level voltage-amplification alone, as in a preamplifier's role. But tubes are technically not ideally suited as output drivers in power-amps where transistors are near-ideal in comparison, a power-amp's output tubes needs converting from voltage-drive to current-drive by output transformers*** for driving speakers & have very low damping factor which can give certain speakers (esp' panel types) a loose &/or saggy or just a rolled-off /lack-of bass in my experience) I have a tube pre & solid-state class A power amp, it wasn't planned because of their internal technology but just ended-up that way after years of progressive upgrading, demo's & trying various 'used' equipment, progressively choosing & buying or keeping the best sounding combinations, irregardless of tube or s/state technology. I've come to firmly believe the best combination (at very least on technical grounds) for pre & power-amps would come from a design that use an all-tube preamplifier & a power-amp that uses tubes for all low-level voltage gain (& transformer phase-converter instead of a tubed one if it's designer went push-pull) & tubed drivers for a transistors output stage to drive the speakers directly. Of course it depends on implementation but if near-perfectly implemented i reckon it would be near-unbearable. ***Output transformer-less tube power-amps exist & i've heard them sound good, but they seem to be a compromise in design, to keep their output impedance down to single figures, if any do? anyway, i never liked the ones i tried. There is a new design of tube amp where the music signal is modulates a very high frequency carrier-wave & side-steps the need to keep tube impedance down with power-sagging, bass limiting output transformers, i've not heard one but the design seems very promising.

@@ThomasAndStereo yes, i've seen that video from ps audio. what he meant is tube output stage on the power amp (most amps have more than 1 stage). to make it work for speakers, tube amp needs output transformers which introduce harmonic distortion at extreme frequencies and some people may hear it as fatten the bass and made treble sweeter. so i think it's only a myth that tube introduce distortion when in fact it's the transformer who did this. for my diy dac i'll only use tube buffer to increase the current without any voltage amplification (no gain) which should be low distortion. tubes have high input impedance and very low parasitic capacitance which fits perfectly for this job. probably this holographic imaging is due to very low and linear parasitic capacitance. just my guess ....

@@ThomasAndStereo I neglected to state that my system is 100% true balanced., annd has been for over 15 years. It makes a huge difference. Also my speakers are Emerald Physics KC IIs (open baffle), 20 amp dedicated line, Core Power 1800 power conditioner, but amp sounds better direct to the wall. CD player is a Marantz HD CD 1, used as a transport via WireWorld Toslink to the AA dac

Thanks for this video. I am having the same issue about my old SS preamp and moving to tubes.

Great, I know tubes do wear out but it's not too expensive these days to replace them. Good luck and if the tubes are exposed, which some preamps love showing them off, they look so cool at night with the lights off.

Thanks Thomas for pointing this out in the most simplistic way. I have thoughts about changing (or rather adding) a tube pre-amp but don't know what tube-centric quality to focus on. Do you have discussion about price point versus performance in tube/solid state amp upgrade for the budget conscious audiophiles?

I will be reviewing a few budget tube gear in the near future. Check out my Prima luna and Schitt Freya video in the meantime.

From a signal processing perspective, a pre-amp between a DAC and a power amp does really nothing getting closer to the original. Already, your DAC output voltage is typically at a line level of what works for a typical power amp. Also, you likely have 100s of transistors involved somewhere between the microphones used to make the music and your speaker coils reproducing it, and tube(s) inside a pre-amp can do nothing other than ADD audible distortion of some sort!!! Obviously it can’t “fix” the damage already done by the many transistors, if any. If you “feel” something magic is happening that makes the sound more authentic, it surely wasn’t there to begin with. Can some even harmonics distortion being added sound good and make you feel it’s more natural? Sure, but don’t fool yourself to think it means the sound you hear is actually closer to the original!
