What can a preamp do an integrated cannot?

How is it possible that adding another unit in the signal chain can be better than having everything contained within one box with a shorter signal path for stereo? And check out our newest KZbin channel / @octaverecordsanddsdst... Octave Records.

This is the most wonderfully explained question about the difference between the two I have ever hard ! Thank you for making these wonderful videos !

[@RealHIFIHelp]

Integrated amps are usually better of cause depending on the price points that are compared. You get more integrated detail, more intimate sound, more music less artifical HIFI effect because of the shorter signal path. Mono blocks with preamp, just usually gives you more power/gain/control which creates the illusion of better sound, but usually the sound is also a bit more flat, where you suddenly also begin to hear the monoblocks, preamps, cables signature on top of each other as separate parts. Huge potential of better sound, but usually it does not happen, unless it is done at a high level so things communicate very well. Most people that have integrated going to this more expensive alternate, just fall in love with the added gain and looking at something that is more cool. That is the precise truth.

[@machone539]

If that is true, then everyone will be rocking integrated amp. The best thing to do is move the power amp part of the integrated amp out of the same chassis. Keep everything separate is what hifi is all about.

[@russputin6294]

It's always been received wisdom that the main advantage of a separate pre-amp is it allows the sensitive, low-level circuitry (moving coil inputs, for instance) to be physically isolated from the noise (induced hum etc) from a heavy-duty power amp. transformer. There are another couple of practical benefits too; it allows for monoblock power amps. to be placed close to the speakers with short speaker leads but long interconnects to the pre-amp which may be advantageous in some circumstances and, secondly, it allows for the upgrading of individual components easily; for instance a better pre-amp, additional power amps. or active crossovers etc.

For an audiophile, having a separate preamplifier is a must as, it gives him/her the opportunity to experiment with many different types such as solid state or valve devices to get the sound that s/he prefers. And even though many people would have you believe that, preamps don't have a 'voice' of their own, reality is, they do and give the whole system a different audible result each time. When you buy an integrated amp. you're 'stuck' with whatever preamp. circuit the designer has given you in the box. Simple as that!

Nope, you just use an aux input for your chosen input device.

Thank you so much for this excellent explanation, Paul. I used to think that running an amp without a preamp was the way to the most pure sound, well, I WAS WRONG, and one of your earlier videos concisely spelled out why. My mistake for not listening to you in the first place. From my research and investigation, I think that the best way to go is to put 75 pct of your money for your front end gear in the PREAMP and 25 pct in the AMP for the simple reason that it's the preamp that colors the sound the way you like it. A good preamp can make all the difference in the world. Again, thanks for the video.

[@nodammit]

I completely agree with you. Decades ago I ran a cd player with a variable output straight into a power amp, and I thought that eliminating an entire component and set of cables helped maintain the "purity" of the signal. Well, a fellow I knew lent me a preamp he was selling and I couldn't believe the improvement it made! More depth, more detail, more bass, etc... I was converted! I would never go without a preamp again. These days my preamp is a two piece unit that weighs 60 pounds, puts out a full 8 watts at the output, and costs more than my power amp.

As a general rule yes, the less power supply you have to share with a given primary function in any audio system the better. Preamp, amp, dac, all using their own power supplies = better. But there are some darn good integrated amps out there that will beat out some separate amp/preamp combos. It's really a matter of research, understanding the unit you want and your given space situation, sometimes separates aren't feasible.

[@Space-O-2001]

Wouldn't you just uprate the power supply to the integrated to get to a supply point where nothing is compromised? (I appreciate probably at the top end driving monster speakers lots of power in a confined space is never good but I'm talking for the vast majority of us who don't spend 5 or 6 figure sums on hifi)

[@sharadhsrivastava293]

Separates would not only sound much better (Caveat: IF and only IF configured, matched and calibrated properly), but they would also make the whole system obsolescence-proof for much longer, as nothing great would change between the power amp and the speakers for many years (and both can last for very long), while the source, pre-amp, DAC, streamer etc. would constantly keep evolving at a much faster rate, in-sync with Moore's Law! If the initial cost were not a concern, separates is the way to go, as it would also open the gateway to experimentation with multiple source players, and different amps - tubes, valves etc. etc. If you don't mind the numerous connectors and cables, that is! 😁

[@paulrs2975]

Another factor: it's best to have the source, especially a turntable, some distance from the speakers. Separate power amp(s) gives you the option of locating it near the speakers with short speaker cables, which is usually preferred.

👏👏👏 best explanation!

[@NoEgg4u]

The short answer is that with separates, each box gets its own dedicated power supply. I cannot stress enough the importance of a quality power supply. It is probably the single most important part of any audio component, and really good ones are hand built and expensive. That is why you can not only go from an integrated amp to a separate pre-amp and power-amp, but you can take the next step, and go to monoblock amps (so that each speaker gets its own dedicated amp, and that amp has its own dedicated power supply that is used for only that one speaker). And to take it a step further, you can bi-amp your monoblocks, so that you have: -- a single amp powering the left speaker's low frequencies, and -- a single amp powering the left speaker's mid and high frequencies, and -- a single amp powering the right speaker's low frequencies, and -- a single amp powering the right speaker's mid and high frequencies. The above, done properly, gives the bass its own power supply for each speaker, and the mids/highs their own power supply for each speaker. In life, equipment or machinery that is well built to do one single and very specific task will usually perform that task exceedingly well.

both have pros and cons. separate preamp is more flexible, you can use it with other systems. with an integrated, you can almost certainly eliminate all hum and feedback oscillation by star-grounding everything on one single ground. separate power supply is not necessary to eliminate interactions between circuits, you just need separate rectifiers and proper grounding. both can be excellent in terms of performance if properly designed and vice versa.

[@stevenkoski228]

Amps & preamps, each generate their own opposing RF fields (LF & HF). When they’re brought close to one another, a noise floor is created; hum, hiss or I/M distortion. Isolating this is a compromise with integrated amps. The end result is resolution suffers from distortion, detail is veiled, soundstage gets displaced. Purists insist on separates, & some have separate power supplies. This all then mandates extra cabling is required, where shielding is paramount to reject RF interference, & material construction to limit signal loss. How much convenience do you demand, & how much trade-off comprise are you willing to accept? Just Keep Listening.

[@jvburnes]

Excellent explanation my fellow Coloradan. My question is more about preamp availability. Its getting really hard to find a reasonably priced and well-performing preamp these days. I can find reasonably priced amps and reasonably price integrateds, but good preamps under $1000 are thin on the ground. "Good" of course being a relative term, but maybe it wouldn't be too much to ask to have a 4 - 5 input preamp with good linear class A characteristics with a mono sub out and a loop back and perhaps a pass through and an active defeat switch (for passive mode) and a decent gain control with a display that shows the name of the input (not just input 1, input 2) with a remote and 12v trigger for significantly less than $1000. I know of only one, the Parasound Zpre3 (relatively hard to get) and close runner up the Pro-ject DS2 Prebox Analog (no display) which is even harder to find. Other than that you have to ask is there a less powerful integrated with all that functionality, but has an very good preamp output stage uncolored by the rest of the electronics? Possibly the Audiolab 6000A or the IOTAVX SA3 both which seem to have well-reviewed sound as long as they aren't driving big / inefficient speakers and perhaps that indicates they have a good quality preamp. They also have phono inputs, which is nice but I can always just buy a separate and same for DAC functionality. Maybe just do the Zpre3, add a Purifi-based megaamp and buy separate bluetooth/DAC/phono stage. Argggg.... About ready to just call it quits and buy a Cambridge CXA61 and an efficient set of bookshelves and move onto a higher end project like my Linkwitz Lxmini and 6 channel digitally crossed-over mega system.

I’m using a hybrid tube headphone pre amplifier as well as a hybrid tube integrated headphone amplifier in my setup. Not bad at all.

Using high resistance headphone / speakers would benefit well from this setup.

All things being equal, and they usually aren't, I think in modern well-designed and implemented gear it's a more efficient, and performing device putting these two things in one box. It reduces footprint, external wire, and matching issues for the consumer even when they use the same products of the same brand. Everything is isolated so well, and optimized so I can't imagine a feature lost by using the same enclosure assuming cost having little or no bearing on it. Another play for separating however may be layout. You could lay two mono-blocks out near the speakers with their heat leaving the control equipment cool as a cucumber centered for a really elegant look we often see in audiophile videos. It really depends on your budget and taste. What I was just saying is performance doesn't really suffer when integration is done right.

[@armarra]

I like your gentle and clear descriptions.. This time I found that the distinction between integrated amp and separate power and pre amplifier was one of concept rather than concrete example. Sure in concept it makes sense but in reality there's likely to be such a small difference in many cases that proponents of separate devices are just blowing wind in typical audiophile fashion. It'll greatly helped your responses if you provide one or two examples to...amplify your point. Pun intended. I have a question.. Is the distortion figures that we see on Integrated amplifiers mainly from the power amplification stage or the pre amp stage ? My thoughts is that it's likely the power amplification stage. I've hooked up a technics su-z980(su-V98 in the states) to a technics su-vx800 so that the su-z980 is the preamp to the RCA unbalanced direct I put to the vx800 as a power amplifier. Am I getting the .007 THD in total or will it be throttled by the worse .07 THD of the su-z980 used as a preamplifier.. I'm doing this so I get remote control of the vx800 volume... effectively.

[@danmarjenka6361]

The whole reason preamps were invented is because manufacturers ran out of room on the front of receivers to put all the knobs added to top-of-the-line receivers in the 1970's. In that day, it was becoming common to have a midrange tone control (I wish that was still true) in addition to adjustable turnover controls for both the bass and the treble, plus a "loudness" button, plus a "Record Out" selector, a speaker selector, low filter button, high filter button, phase inversion, volume muting, and several tuning meters, and tuner settings buttons/levers. Now consider that the tuning dial took up the top half of the front panel of most receivers. At some point, manufacturers just needed more room for the circuitry and more front panel real estate for buttons, knobs, and levers.

Howdy. I have a 2 x 70 W Yamaha integrated amplifier. It is really good. I guess the designers were dedicated to design an integated amp. It has all the usual inputs.

I can't say I observe any significant difference using either one. I use the player preamp because it is more appealing to me.

Easier interfaces and new components with ever expanding capabilities enter our reality like never before.

The amp psaudio makes you mentioned, do you sell it? Thanks

[@W1llSki11z]

When using a pre amp/power amp combo which amp is imparting the sound characteristics? I have an Audiolab 6000A Play that I would like to give some more ooomph to, to drive my KLH Model 5 Speakers. If I add a class D XTZ power amp, is the sound characteristic coming from the Audiolab, The XTZ or a combo of both?

[@garykarlin1777]

Paul, you don't mention at least two of the advantages of an integrated: 1 chassis instead of 2 equals lower cost, and shorter, internal interconnects equals less chance for interference (plus less cord clutter)

[@InsideOfMyOwnMind]

That was a real service bench used by someone who knows what's up and can do real work, unlike the pristine work area where everything is kept "Just so."

[@TheSoundsnake]

First, the way Paul describes the ‘designed from the ground up as an integrated’ is contrary to what he says, certainly different from separates. Keywords: ground loops, output-input matching, interconnects. Some thoughts: 1. Power supplies: you don’t want to have a single power supply for the power amp and the pre-amp. Ok. You also don’t want to have one PS for both channels. So you need 4. Ok. Most pres and power amps offer just one. Separates mostly rule, unless designed the 3rd way Paul described it. 2. It would be best to put pre and power in one casing, an integrated. Why: common star grounding scheme possible, also with separate power supplies. Best to prevent hum and all sorts of ground loop currents. Integrated wins. 3. Connecting two amp stages requires matching impedance and capacitance load. The interconnects interfere with this (just textbook electronics), altogether they act like filters. So connecting both stages causes issues, and hence all the fiddling with matching equipment and interconnects. The longer the cable, the bigger the problems. What about the speakers? They’re are passive devices, not so many issues with cables, as long as they’re fat enough to transport the current. Integrated wins. My £0.02: an integrated could be better. But integrated amps are never build to the spec separates are build. Understandable, as it would be more or less impossible to put a real beast of a power amp on the bookshelf. And they won’t be small and light, due to the heavy power supplies and heat dissipation. So in the end you’re required to deal with separates if you really want TOTL. And deal with the matching and cabling troubles. Or just listen to the music.

[@The09221955]

Would it keep costs down to combine them?

[@edgar9651]

As far as I know a nice (pre)amplifier enclosure cost a lot of money. I am sure that is a place to make a combined product more cost efficient.

[@eugenepohjola258]

Howdy again. There is one good reason to use separate preamlifiers and power amplifiers. That is the desire to use graphic equalizers. If possible to aquire the loudspeakers sensitivity graphs one may compensate the unlinearities of the frequency responses. Particularily bothersome are the bass element resonance and the tweeter resonance. The former causing a pealing sound and the latter annoying whines. A graphic equalizer may actually make the speakers sound one price class better.

[@xfilesfoxisdead7979]

Yup. I listen cds , original ones bought at shop. Im old shooled

[@r423sdex]

Well I listen to cds , they sound superb. You can't hear hires audio anyway total waste of time.

[@LanciaD50]

Me too. After years of raspberry and streaming service, I'm come back to cd player and turntable

[@r423sdex]

Is anyone thinking of getting a CD player or just a transport ? I am thinking of the hegel mohican or Cyrus xt signature.

[@r423sdex]

I have just inherited a vinyl collection from my uncle, all the classic albums .most are first print. They are from the 60 70 and 80 about 3000 of them. Not sure if I will get a record player though.

[@r423sdex]

@room-ten-oh-nine ! Would you play mint albums like pink Floyd dsotm first pressing.

[@marcusbrsp]

What about if you only have one source, maybe a media transport, that is connected to a DAC which in turn is connected to a power amp? What would then be the point of adding a pre amp in between the DAC and the power amp? (Knowing you would not need more input sources.)

[@davidlane1169]

Ideal for an active speaker setup rather than a passive crossover speaker. Cleaner, no bulky amplifiers to create heat, cooler by miles than a integrated unit. Most audiophiles would prefer a preamp.

[@davidlane1169]

Funny, I had two old perfect quality stereo preamps stored away for future use. One could pick them up commonly for about $75, I purchased several Carver units at that price or even lower. For some reason, analog preamps had temporarily run out of favor in the mass market. Folks are idiots the world over...

[@davidlane1169]

Lack of a digital tier more than likely the culprit. Easily remedied.

[@rockyslay4310]

My tube power amp is 35kg and I can barely carry it so the pre amp will need to be seperate haha. I wish I could try it out with the Stellar pre amp DAC. One day!

[@mahessilva7504]

Hello Paul, Iam Mahes from Sri Lanka and very happy with your videos! Please keep up the good work!. My question: What if an integrated amp is designed in a Dual Mono configuration? Can it eliminate the usual cross talk? I use 2 Musical Fidelity integrated amps, A308 and A3.2 both designed Dual Mono and they sound perfect though both are as old as the hills!😊

[@Paulmcgowanpsaudio]

Yes, a true dual mono design should be able to eliminate crosstalk. Absolutely.

[@r423sdex]

You can get pre power amps and dac with network streamer all built-in to the speaker, and these will make huge improvement over the next couple of years. Kef ,dynaudio ,Elac and dali to name a few.

[@k-doggy1762]

Can't really upgrade different components with all in ones though

[@ardemus]

Interesting. It makes me wonder about the PS Audio Integrated devices. Are they compromised or just separates stored in a single box?

[@arun2995]

What the are you talking about? PS Audio does not make integrated amp. He is talking about the different between a specific product vs cost, Integrated vs separate. Every product has to have a cost vs benefit other wise everything would be a cost no object item. I clicked on this video because I wanted to know the answer and it actually answered it very thoroughly.

[@beagle7622]

My problem is what type of cable do I use between a pre & power amp. The integrated can have very good wire inside the box.

[@paulffake]

The OP was asking what the point of having a preamp in the first place would be instead of just plugging a source directly into a power amp. Paul got the point completely wrong and answered a different question. My own answer would be that certain sources could use a bit of gain from a good pre. A good pre will also have a decent phono stage (or not) and besides switching and volume control, might have EQ or tone controls that (heaven forbid) you might want to use to tweak the sound coming out of your speakers. Or to use as a headphone jack it’s no speakers. Also, there are many vintage monoblocks that don’t have any volume controls and need a preamp in order to control. And there are lower powered or low sensitivity monoblocks that benefit from a hotter preamp signal. It you have more than one source, you need a preamp.

[@nickguillem1040]

The objective of asking all about these gadgets is I strongly believe to hear confirmation that connecting these makes the audio coming out of our devices better. If there nothing to gain then there is abolutely no need, just stick with the most conventional or even the cheapest.

[@berduss7149]

I have an Atoll in50 , and I use the pre-out for a power amp . So my integrated serve only has the preamp . And if something apen to my power amp , well my Atoll his a good back up :)

[@MaharionPendragon]

So... if I have already have a good AV receiver, do I still need or want to connect a preamp to it? I saw some tech videos promoting this on youtube

[@f430ferrari5]

If you’re happy with your AV receiver then no you don’t need a preamp. If you keep switching out speakers though the issue may not be with the speakers but with your source.

[@sebizbir]

Hello, why most of pre-amps do not have the phone stage?

[@sickjohnson]

Here I was thinking that the single biggest advantage of a pre-amp was improved signal voltage to the power amp, from the source...?

[@musicman8270]

On an integrated that's not even an issue. The biggest advantage is flexibility, being able to swap out your amp or pre, and being paranoid about breakdowns,a backup plan is more easily implemented.

[@xr500t]

Can you add a pre-amp to a receiver?

[@crazycanadian2560]

here is the real question I have I own 2 nad power amps 275bee Now i have to amps that can run them .. one is nad 165bee preamp only.. and the other is nad 326bee intergraded//preamp option as well.. the 326 is much cheaper then the 165.. like 3 times cheaper yet you can use the 326 as a preamp to run power amps is there a big difference in quality of preamps in the 2?

[@luistguadalupe7188]

I have a Adcom preamp with an extra pre out labeled lab,can i connect a power subwoofer to this output since it doesn’t have a sub output build on it?

[@genez429]

One Adcom manual manual (GFP 565) states as long as you are not using any tone controls, its a direct coupling output. (no filtering) I suppose a sub woofer would work well this way. www.manualslib.com/manual/206154/Adcom-Gfp-565.html?page=9#manual

[@infrasonicrebasses4763]

honestly....you don't even NEED pre amps....you don't really need it ...especially for home theater or any sound reproduction device anyways ...the amplifier itself already does all you need ..only thing if needed after the signal source would just be some DSP for some very fine tuning ..and pre amps can't do that

[@suprgx472]

The user should have given his equipment set up. I had a pre amp and a dac running through the pre amp into mono block power amps. The pre amp failed( no volume) so I was able to plug my dac through xlr directly into the power amps. The dac has its own volume control. The dac has balanced and unbalanced output. I used the unbalanced output of a 600 watt powered sub. By being forced to eliminate the preamp my system improved markedly.

[@eyesolatedrock]

I don’t know that Paul answered the question. I think the question was, can he directly connect the source to the amp without a pre-amp. If you only use one source for listening, do you still need a pre-amp? It wouldn’t be as loud, but is the extra gain/volume worth the price?

[@markdoherty2750]

Can anyone help- I am using my Audiolab 8000a integrated amp as a pre-amp and connecting to my Audiolab 8200p’ power amp. I am wanting to move up to a dedicated pre amp but am mindful of the cost. I am considering a Audiolab 8000q if I can find one? Thanks 👍🏼
