Just keeps getting better and better! Super excited to see what this year brings! On a side note, before you drop 30K on those Kef's would be awesome if you got your hands on the new SVS towers that have two sets of opposing subs/woofers each to see if they can come close to the Kef's for much less!!

[@ufarkingicehole]

John Curl covered the topic of distortion really well. He specifically cobered second, fifth, and seventh orders of distortion extensively. Not all distortions are unpleasant to the human ear, which is impart why a lot of people prefer the sound of tubes over ss. Very interesting stuff from a really interesting guy!

[@stevenneese2823]

Keep it up Erin. I've always thought about getting a pair of Tektons. Your review made me want a set even more. Now, after hearing about what they are doing, I'll never even give them a listen. Dead to me. Shows the true colors of that company. We need to make sure this is never forgotten.

[@AudioIdeas]

This was honestly the best amp review I've ever seen

[@ErinsAudioCorner]

Oh dang! Well, thank you!!

[@calebkeen8967]

I completely agree that any product with a sub-out should have high-pass/low-pass built-in with an identified slope at this point. The higher the cost, the more flexibility you should get w/ crossover frequency, slope, phase etc. This would help solve the biggest problem with subwoofer integration; running the mains full-range and cancellation throughout the crossover region.

[@edwardasmannjr.2438]

Adding my vote. Yes, if it has a subwoofer output but does NOT include a high pass filter for the mains, at the same frequency and at least a 12 dB per octave slope, or steeper, then I am disappointed and probably would not buy that equipment. That’s what I would do/not do. What others would choose is their business and that’s fine.

[@amb3cog]

The whole point was that he was criticizing that one cheap amp for not having it. When the majority of amps in every price range lack this feature also. It's only very recently that we've begun to see amps add this feature. And honestly some of them really suck too. I saw a review the other day where it was locked at 150hz. My subs don't even go that high. Not that I would want them playing that high even if they did. I would much prefer that it's either fully adjustable. Or not at all. So I can get it exactly where I want it myself via my MiniDSP. But again that wasn't what people were complaining about. It was about him criticizing one little company for doing what's been done by every company for years now. ✌️

[@amb3cog]

Actually I would be fine if it were set at one frequency too. But only if it were able to be turned off via a switch. Otherwise full signal is better IMO. A simple, and cheap capacitor on your mains (AKA Bass Blockers in car audio) can get it to the exact frequency you desire also. If DSP is too pricey. ✌️

[@calebkeen8967]

@@amb3cog If you have a miniDSP you don't need a "sub-out", you just need a variable gain pre-out. A "sub-out" should be designed to assist in integrating a sub, which requires a high-pass/low-pass filter and ideally the ability to manage a few other variables. You're right that most integrated amps don't have this, but that's not a reason to not wish that the ones that do provide a 'sub-out' implement it correctly.

[@amb3cog]

@@calebkeen8967 I'm well aware of what I need, and don't need. That's irrelevant to this conversation though. Especially since I use an SHD Studio. And don't want to have to use it. At it is. I don't use it much at all anyway. It's just part of my large collection of HiFi stuff. But this means I need a DAC also if I want to use it that way. Instead I use the preouts from my Exposure 3010S2D full range to my REL subs. And run my Kef's full range also. Works great. Flat down to just under 30hz in my small room. I prefer preouts over sub outs for versatility anyway. My point is. I don't want too much of my signal chopped off, because I cast get it back. But I can always remove easily and cheaply enough. It's my unit. I want control over it. Or I'm not buying it. Your opinion is different. That's fine. I've made my point. And you've made yours. But you're not going to convince me to change my mind, because to me your argument makes zero sense. And I'm sure you feel the same way about me. So let's not beat a dead horse here huh. And agree to disagree. Enjoy the music. ✌️

The HTA200 has turned out to be a perfect match for my older MatinLogan Aerius 4ohm electrostatics that graduated to my master bedroom. I’m impressed with it. I’ll probably change out the fan with a quieter Noctua fan at some point since that can become audible at times, but great little amp for the money!

[@mackenmetal7853]

Love how you are constantly keeping yourself honest with this new blind A/B testing in your subjective testing, as when it comes to audio it is so easy for any of us to catch ourselves validating what we think we hear. I actually have one of these units on the way already (sucker for the vu meter and the tubes) and so found your analysis really interesting. I guess since you didn't notice the bump in the higher frequencies as much this might be due to the speaker profile already having a strong enough high frequency output. I am currently considering getting a pair of lintons and I wonder if that uptick in the higher frequency would be more noticeable in a speaker like that where there is a strong rolloff of the higher frequencies. I get the impression that they could pair well together assuming the bass bump isn't too much.

[@eucariote0uh1]

Great new direction with the blind comparisons! My buddy and I did blind test comparison of three different headphone amplifiers with Sennheiser HD650 headphones, and we could not tell a difference (p>0.05).

[@chrisyoung8946]

Thank you for this!

[@TheFrugalAudiophile]

I agree, I too prefer amplifiers that have some type of high pass filter available when implementing a subwoofer. A low pass filter on the sub out is nice as well but not necessary since many subs have that option built in.

[@WestonWill]

I have a hypothesis that those who enjoy a tube amp tend to listen at a lower level and the amp provides a built in "loudness" curve. Tube amps, for the cost, have less power so the listening level is further limited. Tubes just look rad! I would like to add one to my system at some point.

[@ErinsAudioCorner]

Seems plausible.

[@BostonMike68]

That's a hybrid so it has a tube pre amp and a b power amp of 100 watts. But it has tone control so you just lower it a little . I think he has OCD

Great review, I'm learning a lot. I can't place my speakers against the wall because of furniture and a fireplace ( 2 different rooms), but I don't think I'd buy a specific amp to compensate for bass loss because it. I have always been concerned when I hear a component needs to be matched to another specific component for best sound.

[@QuintEssential-sz2wn]

Brilliant! Love the introduction of ABX Erin! I'm going to mention my own blind test of tube stuff. But first: I'm pro blind testing for the obvious scientific reasons. I don't think any audiophile HAS to bother blind testing, and often enough I can't be bothered. But when I really become curious if I'm hearing real differences or not I will do blind testing (level matched, randomized etc). So for instance I've blind tested CDPs and DACs (positive for differences), some well known audiophile AC cables (negative), high end video cables (negative), compared music servers (negative) and other items. I'm a tube amp kinda guy and have used Conrad Johnson monoblock tube amps for decades. I've also had a number of solid state amps in my system through the years to compare and every time I've preferred what to my ears was the richness and slight upper midrange/lower treble "sparkle" of the tube amps. I always thought it would be great to blind test the tube amps against the solid state but there was just no easy way to manage that. But I also have a CJ tube preamp and a while back bought a Benchmark LA4 ss preamp to dip my toes back in to more neutral waters. The Benchmark preamp has such a low noise floor I was able to route my CJ premp through it at unity gain, and with the Benchmark remote I could easily flip between the signal only through the Benchmark vs running through the CJ preamp. In sighted listening there seemed to be a very obvious sonic difference - similar to what I hear in my tube monoblocks. Fortunately this set up allowed me to easily do a blind test between them as I could use the Benchmark preamps volume to level match (also at speaker terminals) and with a helper we randomized switching (using an online random number generator) while I was blinded to the switching (my preamps are in a separate room from my listening room). Results from two trials was 14/15 and 15/15 correct for identifying the tube preamp. And I identified the tube amp via exactly the sonic characteristics I had heard in my sighted listening. I don't therefore assume all tube equipment is similarly identifiable and there's so much room for bias effects "those glowing tubes will make the sound 'warm.'" But it was interesting in at least this case that the "warmth/upper mid glow" characteristics that I'd always loved seemed to translate in the blind tests as well.

[@SDX9000]

Impressive, only you results with a tube amplifier are 100% expected as your test did not include _matching_ of the frequency responses of the amplifiers (note Richard Clarc allows to choose which amp will be matched to which, so the "looser" cheap amp gets the ugly DSP processor or any form of EQ attached to it). If you can measure that both frequency responses match to within

[@QuintEssential-sz2wn]

@@SDX9000 I'm somewhat confused by your comment. Why would one want to match the frequency response between amplifiers? If there is a frequency response difference through a speaker between two amplification devices, that's just the type of thing we'd want to know, and in principle could be identified in a blind test. In other words: using one amp would sound different from the other. What am I missing?

[@SDX9000]

​@@QuintEssential-sz2wn The reason to match frequency responses is grounded on the expectation that: If a "cool", expensive, special AMP1 is truly special, then it should be more than just a slight frequency response difference. Therefore Richard Clarc's test matches volume not just at one frequency, but at all frequencies (that's the effect of EQ). Notably it gives an ADVANTAGE to the "cool_AMP1" by adding a cheap, simplistic DSP or EQ into the signal chain of the "undesirble_AMP2". So, after equalization ABX test would surely reveal that: "cool_AMP1" still sounds clearly different (likely better) than "undesirble_AMP2" that is extra-impaired by "not_broken_EQ" to match frequency response to the pristine "cool_AMP1".

Awesome review! I love it when a reviewer explains WHY a component sounds the way it does rather than just telling us how it sounds and therefore if its a good or not so good product. Subjective reviewers that dont include the techincal aspects of the components influence on the sound just dont do it for me.

[@ebkesq72]

Erin, you are not the only one-I have said on ASR for years that the “warm” sound ascribed to tube amps is not due to any kind of “euphonic” distortion but rather is due to their frequency response deviations, and possibly damping factor. Not sure if you read those posts on ASR, though.

[@djg6015]

Thanks loads. +1 on the sub out with no satellite filter. It's why I moved away from the 2.1 chip amps. I have a Dayton 8" kit built DSP subwoofer in my PC nearfield system. That sub extracts the lows and sends the rest on to the satellite amp. You might consider testing that kit or one of their DSP sub amps. They can be adjusted on the fly with a Windows PC GUI. Very cool. Especially since the lack of a satellite filter bugs you as it does me.

[@middleearthltd]

If I bought an integrated amplifier with a tube stage and it had a neutral response I would be disappointed If the tube implementation was to my liking then good As I recall this do have a tone control so turn turning the bass knob left may suffice This may be bad implementation for my tastes, or not There is a review of the HTA 100 on a popular subjective channel that was positive but that is a tube appreciation channel and I am in that class Your reviews are nice in bridging the gulf that exists between team ASR and the subjective reviewers who both make sense to me Great work on this review Thank You 🙏

[@richardbixler]

Great review as always Erin! Forgive me for my lack of technical knowledge here but I have a few questions. It seemed like the Daytons clipping point was a lot more linear and smooth. Is it fair to say that speakers that clip more easily would benefit from that characteristic? Also, would you consider trying another ABX test with the bass and treble adjusted to a more flat response? I’m really curious if the power/THD and dominant 2nd order distortion would be enough on their own to distinguish the amps sound. If not, thanks anyway for all the time and research you already put in. In the meantime I’ll check out the other review you referred to. Thanks again

[@richardbixler]

Ok, so o read the review from soundstagenetwork. I think I found something interesting. I’m not an expert in audio, and I could be totally misinterpreting this measurement. So admittedly, I’m literally talking out of my A** here. But the writer, says this: “The HTA200 appears to invert polarity and yields an astonishing -60000 degrees of phase shift at 20kHz”. My interpretation is; that the tube stage can’t reconcile any information above 20kHz and reverses phase of any signal above 20kHz. This would explain why these tube preamps seem to work magic on the soundstage. They buffer out high frequency distortion, allowing you to really push a speaker to its limits without it sounding shrill or sibilant. Also, possibly providing a larger soundstage.

[@SDX9000]

Excellent point. When frequency response is so obviously "creatively shaped", all other aspects will be near-impossible to assess unless the frequency response is EQ-ed out of the equation.

[@markpocock183]

Thanks Erin, great review. You described the AB comparison...did you use the X? I assume it has it, where you know A and B but don't know what X is, and try to match it to either A or B. Perhaps, in this case the difference was so obvious it was not necessary, but for subtle differences this is a great way of proving you dud (or did not) hear a difference.

[@joentell]

I would want one of these just because it looks cool, but I would still use DSP.

[@sk9592]

Say you use EQ to approximate the same frequency response changes that tube amps make. Do you think you would be able to tell the difference between a tube amp and EQ in a blind test?

[@BriBCG]

In a world where it's easier than ever to add powerful digital filters to your sound chain I just find it hard to understand how much people are willing to pay for products that's only trick is to add their own brand of coloration to the sound. Tube amps maybe a bit of a special case because of the distortion characteristics that might be a bit more difficult to add, but frequency not so much.

The fact that you could easily hear that bump in the bottom end, but not hear the bump in response at the top end, is why I always tell people not to worry about response characteristics of speakers above ~4Khz. Bulk of musical energy and ear sensitivity is from ~40hz - 4Khz. Everything above that is just the "air" of other sounds with lower fundamentals. Big response variation in the top 2 octaves can generally be ignored. medium response variations above 2khz are also pretty inconsequential, small response variations from ~100-1000hz will be apparent and change the "signature" of the sound, as this is where almost all vocal energy lives, and lots of instruments. Many of the best sounding speakers out there sound great because they are flat and clean ~100-1,000hz while having less than ideal looking response outside of this range.

[@SDX9000]

Hmm, Sean Olive has commented on several occasions that in Harman listening training people often confuse bass-boost with treble-cut and the like. It is natural that people react to the overall slope and do not care about all subtleties if the difference is already obvious. Your conclusion would be supported only in case Erin would EQ-out the bass-boost-part and then still fail to detect the difference in treble.

[@BostonMike68]

I really wish he did more of a review on how he likes the way it sounds, I get it about the bass boost but why just focus on the boost especially when it has tone control, which I like because not all recordings are equal and I'm not one of those people that thinks " the artist attended it to sound" because most of them were coked out of their minds 😂. I like to be able to change the tone and maybe they did that to give a sense that it is the tube sound. But we get it it's colored but what about the rest of the review?

[@StrangeBrewReviews]

I'd love to see a review of their new A400 high power amp that just came out a few weeks ago...big power

[@FOH3663]

Perhaps your perception of the high freq contour was impacted by filter Q. The LF boost is nearly four octaves wide. Whereas the HF boost is under two octaves wide. Our perception is more adept at low level broad EQ'ing, rather than higher level, narrow EQ'ing. What a cool piece, you've gotta love Dayton.

[@tbreit]

The integral of the low frequency energy under that curve is massive and would be audible on any decent speaker. I would really prefer to see a good AB test (ABX actually) with two amps of similar performance.

[@rehn1kri]

Thanks Erin. Did you also listen for other sonic differences between the three amplifiers in the blind testing…soundstage width and depth, image specificity, overall resolution, etc?

[@ErinsAudioCorner]

Honestly, the bass stood out so much that it eclipsed my attention for listening to any other differences. Maybe if I had EQ’d them to not have the bass profile I might have heard other differences but I can’t be certain.

[@SDX9000]

@@ErinsAudioCorner Amen! please run it throuhg a Richard Clark amplifier challenge routine (using the cheapest miniDSP or other EQ box to quickly match the response curves of a reference amp to the response of the warm device under test)

[@richarddoberstein8308]

I have this amp, Don't you think the freq response curve could have something to do with the tone pots? That is the first thing I would suspect.

[@madcrabber1113]

I agree about the high pass for subouts.

[@BostonMike68]

Yeah I have one of those , you can adjust the bass with tone controls so it's not a big deal, but I wish it had a high pass , but for $350 it's a nicely built and really good sounding amp. I think he's to concerned about a measurement that has tone controls and it's aggravating having him go on about an amp that can easily be adjusted

[@paulwilliamson3798]

Have the HTA-100 and minus the remote, it has been a solid affordable desktop amp.

[@mrboat580]

Good video. I had a Dynaco that was cool, some tube preamps, a hybrid and some DIY versions but the novelty wore off for me with regard to both the looks and the performance. After a spell, I start second guessing the degradation of the tubes. I'd rather have a solid state with basic tone controls more than tubes.

how about you eq(maybe through equalizer apo in a desktop setup or the computer as the source, then use the phone to control the computer screen will stay still or something) this amplifier to match the other one you have and redo the A/B test, if it's really just the frequency response that causes the sound difference and not something else(maybe in/output impedance, capacitance in the signal path, or maybe it's really the distortion, that while maybe not hear-able, feel-able, and/or like subbass or really high treble that you can't hear but still give a stress to your ear)?

[@hugoeilertsen4459]

Been owning the HTA 200 close to 2 years now and its a steal. I use it on a pair of Faital 3WC 10 by DIY builder Troels Gravesen. These are 3 way speakers with 10" woofer and a sensitivity at 91 dB. The cost is 2,5 - 3 K$. When l finished the kits, l first tried some 6 - 8 amplifiers among them a Musical Fidelity 225 and a Line Magnetic 216ia. But none of them could match the HTA 200. The midrange magic and the 3 dimetionality. Could it be that the designer of the speakers love tubeamps?

[@jameslaidler2152]

Hope youre doing alright mate!

[@ofergover2978]

Hi Erin, great review. What do you make of all this measured distortion? Is this tube related? seems higher then other amps you tested.

[@ErinsAudioCorner]

Honestly, I’m not sure what’s driving the high distortion. There’s a lot going on in this amp. And it could very well be intentional.

[@ofergover2978]

Thanks, how audioble is the fan? Also maybe you can review a pro amp like Crest or Beringer. Audiophiles don't like them so much but in my experience they are great vfm.

[@steveh545]

cool. I recently bought the Douk audio equivalent (Nobsound) AND a Wiim amp, and a Douk A/B switcher for amps or speakers. NOT blind. I switch back and forth regularly. I bought all of this together with the goal of keeping one amp. I'm sure i'll keep both, lol. The Nobsound is also cool (just not quite as cool looking at the Dayton Audio. I find both amps need a little eq. through the Wiim amp (or WiiM mini connected to the Nobsound). I can synch the Wiims so the music doesn't skip a beat. Of course the Nobsound is using it's dac with the Mini, and the Wiim amp is using it's internal dac (another variable). So, what did i learn? Not much. It's fun to flip around. For my ears, and my speakers, and my horribly bad (acoustically) listening room, i need a little eq. Basically, i have to flavor for taste. For some genres i prefer the Hybrid, and others I prefer the Wiim amp. No golden ears here, or golden budget, but for the price of either, it's hard to argue a whole lot.

Does anyone know if I can run a EQ with the Dayton HTA 200?

[@derekf7772]

Were there any audible effects on soundstage or imaging? Was the sound any more holographic?

[@Mishael_Agyei-Boamah]

No, as you can glean from the review... It only affects the frequency response. Doesn't add more dispersion

[@howardskeivys4184]

Amplifiers unquestionably sound different. There will be similarities, but the differences will be noticeable. Will be the reason you choose amp-A over amp-B! For over 20 years, the beating heart of my Hi-fi system was my trusty old British integrated. That amp is still in current production, though now sports a remote control, mine doesn’t. I recently took that British integrated amp to the local dealer to be returned to the manufacturer to be refurbished. When it came back into the dealer, they persuaded me to audition the 2 amplifiers higher up in the manufacturer’s integrated range. I agreed to the audition providing it was totally blind. Within seconds of the first track, being played through the first amp, I knew, unquestionably that, that amp was my trusty 20 year old. I was right. I was also able to identify the other 2 amps with a 100% success rate. I have more recently seriously upgraded my amplification. I’m using 1 premium preamp to control 2 pairs of monoblocks. I can run them concurrently, or separately. The difference in sonic signature from each pair of monoblocks is unmistakable!

[@sk9592]

Say you use EQ to approximate the same frequency response changes that tube amps make. Do you think you would be able to tell the difference between a tube amp and EQ in a blind test?

[@ErinsAudioCorner]

I don’t know for sure but I’d say probably not. The difference I heard here was in the bass/lower midrange. I didn’t hear any changes in soundstage. But I suppose it’s possible if the clearly different response profiles were made to be the same. Though, I doubt it.

[@derekf7772]

Id be interested in seeing a test on a tube amp with tubes on the actual output. Then we can see how tubes interact with the load a speaker presents. I can’t help thinking tubes on the preamp seem kind of fake (?)

I’d like to. So far I haven’t had any luck getting any.

[@botwally2954]

I think a good idea for maybe a future video is to test the Dayton HTA200 vs a neutral amp but with EQ applied to match the frequency response of the HTA200. Basically, I would love to know if 2 amps that have the same FR (EQed to match the same FR) will sound the same in an ABX test.

[@ErinsAudioCorner]

Good idea. If they happen to tell me to keep this amp then I’ll do that. But I boxed it up and planned to ship it back to Dayton.

[@markpocock183]

We did a test like this when I was at university, and when matched tor level and frequency response, and not driven into clipping, nobody could hear the difference under ABX testing. ​@ErinsAudioCorner

[@SDX9000]

@@markpocock183 Thank you for feedback. I always wondered what about the hiss? Supposedly up to 2% THD is not a problem, but the hiss during quiet moments should be noticeable on some amplifiers and in-audible on others? What would be a threshold for noise floor then?

[@dougg1075]

High efficiency speakers would be great with the bass profile of this amp.

[@celstark]

Dollars to doughnuts says they baked this in to sound “warm” and “tube like”. The analog inputs are digitized and I’d guess this curve is baked in with DSP. There’s no inherent reason why the tube stage would have this non flat curve.

[@ErinsAudioCorner]

Indeed, I believe you may be right. SoundStage’s review found they digitize the inputs. So maybe it is DSP doing the heavy lifting of the “warm sound” here. 🤔

[@mdocod]

The lack of HPF in most of these little integrated amps with sub outs makes them pretty useless for 2.1 applications IMO. Agree with your rant on that 100%.
