"May your air be most wiggly," is the best sign-off ever.

You have this ease of putting complex and specialized subjects in a language that the layman enthusiast or semi expert can understand. I may have gotten about 60% of what you were talking about but I completely got the point of what you were trying to demonstrate. Huge takeaway for me and major props to you 👊🏻

As a retired measurement engineer with 42 years of experience I fully agree with this video. You have just scratched the surface. But the real take home on this subject is if the measurement is “excellent” then the likely hood of you hearing that difference is minimal given all the other compromises in a real word system. If there is a difference heard then it will be associated with a difference not covered by that particular measurement. Audio reproduction is complex and one must look at perhaps 20-50 different specific measurements to make a valid comparison. Keep up the excellent work.

I really enjoyed this video. The question I'm usually left asking upon visiting ASR is "Yes, OK, but did you LISTEN to it? How did it SOUND?" They seem to value 1) measurements, 2) loudness, 3) looks/form factor/aesthetics, and somewhere--way down the list--how it actually sounds.

It’s unrealistic to expect people to shoulder the costs required for such testing. Relying on one’s ears is not necessarily a simple concept when there is cost involved in procuring or encountering the equipment necessary to experiment, along with the time and effort to even work through the process once it’s been enabled. Also, people can imagine they’re better than others at all different levels of a situation like this (ofc for differing reasons), so I won’t address that further.

Totally agree. I find ASR to be just as disingenuous as any subjective reviewer - either that or just ignorant.

As with nearly all measurements, they are far better equipped to inform us about possible flaws than to educate us on sound, as experienced by the listener.

Fantastic video. An excellent challenge to those in both the objectivist and subjective camps that not everything is black and white. Audio, like life, is nuanced and open to interpretation.

Awesome and AMAZING Explanation! Great job!!!!!

Thanks a ton for this video. Hugely valuable to advancing the discussion

The problem I have run into is that the gear the measures well doesn’t sound great and the gear that sounds great doesn’t always measure well. Thd and Sinad in my experience typically have little correlation if the amp will sound well (subjectively). So I’m struggling to use objective data when subjectively my Brain is telling me otherwise. Perhaps I enjoy distortion perhaps we cannot measure that which I enjoy or perhaps the measurements are just wrong or inconsistent as you state.

It also have to do with loading of your speaker because of the complexity of crossover and drivers. Those two are just measuring noise nothing else. Like Benchmark AHB2, it is the best in ASR. But you see some user returning this product. It is also well measure in Stereophile. You have to listen to amp with the speaker it drive in subjective way. No way to tell whether the product is worth buying just looking at graphs. I mean lots of people can swore by 300B including me.

I had my account banned after I said I could easily discern the SQ of each of my DACs (all ASR-SOTA level). Even after I followed their null test requirement and the test result 100% supported my judgement they started to ask for further testing seeking a way to disqualify my listening tests. They don't accept that measurements are always incomplete by nature and that listening to the devices should always be the deciding factor.

We needed this video so much. This is part of why I never really paid attention to measurements. I give more credit to subjective feedback, especially when I could validate their impression by testing a piece of equipment myself. It worked for me and I am happy with what I have.

Thanks for all your great reviews, I really like your approach. Useful measurements with a serious analyzer, combined with subjective listening experience, Perfect! May I suggest the Bluesound Node (N130) for a review with all the measurements. I've got one since a week and the subjective listening experience is much better than with my Sonos Connect(with Tentlabs clockmod), both using an external DAC, BlackLion Sparrow Red. I guess the clock of the Node is quite good and has low jitter, could you back up my guess, or proof me wrong? ;)

I'll stick with my ears and brain measuring how much pleasure i get from any bit of kit. Topping A90 measures incredibly well, i auditioned it and hated it bigtime. Bright, harsh, cold, not a great soundstage and just not my cup of tea. I auditioned the Benchmark HPA4, what a fabulous amp, another THX amp that measures extremely well but completely different to the Topping. Sounded next level with my planars, made them sound like electrostats however, a bit too neutral for my HD800. In the end i settled for a Violectric V550 Pro, works really well for both cans and while i have no idea how that measures i really loved the sound. I'm very glad i take little notice of measurements. 👍

@KaneAmaroq

Interesting experience, I've used an A90 and couldn't possibly describe it any way you mentioned. To me it just sounds 100% uncolored. No harshness, definitely not bright at all (it's totally flat, after all), and cold... Again. it's extremely neutral. I think you might just have a preference for warmth, AKA boosted high-bass/lower mids. To me it sounded 100% identical to the HPA4 I demoed. Not a lick of difference between the two. But then again, I also level-matched both with an SPL meter, swapped between them within 0.5 seconds using a switcher, and did it completely blind. If you don't take those into account, your sense of expectation WILL affect how you hear. It is 100% unavoidable. That's why you can't really trust your ears for anything but preference, UNLESS you eliminate every single factor that can influence your sense of hearing.

This is like the matrix moment where neo sits in the chair and gets information downloads. :)

Brilliant, thanks...

I love this kind of video

Very well organized, I enjoyed it a lot and it highlighted a lot of the parameters that can affect the measurement outcomes of a device. One thing I'd like to contend about (or would like a more detailed explaination of) is if the Rebel's "warmth" could be indicated by any of the measurements you have made. You pointed out in 21:14 that its THD+N ratio rises with frequency, but I fail to see how ~0.02% at ~10khz is even significant for audiability (taking into consideration 1. the absolute threshold for hearing and 2. masking due to ambient noise and signal).

I'm on board with the intent of this video. In any engineering test you document the procedures and the findings. That way someone who wants to repeat the test can do so and they should then arrive at the same result. Where there are differences are almost always attributed to the test procedure itself and not product variation. This is standard stuff in every field. Not just audio components. Anyone who takes issue with your encouragement for that are simply doing so out of spite and letting their emotions override logic. So, yes, document the procedures and publish the results. Simple. I also agree that often too much importance is placed on a single value metric (such as SINAD) and the other parts of the whole are tossed by the wayside. However, you lost me at 27:30 with the statement that "two devices with the same SINAD levels can sound very different". While I agree this is certainly possible, you provided a generic statement with no footing. You spent the better part of 25 minutes making many valid points with examples. And then you dropped that statement as if it were an afterthought. I wish you had taken steps to provide an example of when you have seen this and then provide reasons why that was the cause (i.e., frequency response, different voltage levels needed to reach this SINAD match, etc). This, to me, is much more helpful in providing rationale for a) why measurements can be misleading and also b) how proper measurements can help us learn *why* Product A sounds different than Product B. In my opinion, that should be the goal of a reviewer using data to help supplement their review. I don't believe it serves much purpose to say "here is data, and by the way, this is what I heard" without at least attempting to reconcile those two things. At any rate, I hope you understand where I'm coming from and don't take this personally. Overall, I'm in complete agreement. I just think this video would have benefited the community if you had taken the extra step to explain your ending statement (or you had simply left that out). Maybe that's a topic for a later video... Take care, Erin

Reading the topic on a certain forum and seeing how they take things out of context so much is painful.

"How does it sound" I've always found this question interesting, because whenever I've listened to different source gear (outside of tubes/vintage stuff), to me it always sounds like... whatever I'm listening to. I think the only amp I've ever listened to that sounded any different than other amps has been the Jotenheim, in which everything felt like it was bleeding together, almost muddy. Same with any kind of lossless and above, same with DACs. No matter what headphone, no matter what source, I always just kind of listen, and go, "...That's it?" Not only that, but when half the people who say it's a night and day difference, whenever I bust out my switcher and SPL meter to do some matching, whenever they blind-switch between the two, suddenly they have no idea what device is being used. So... I dunno. I think both camps take themselves far too seriously and think they're just imagining stuff, which is super easy to do with your auditory perception. Just get a headphone you love, a nice, clean amp/DAC, and enjoy your fucking music. If you want weird flavor, that's what tubes/EQ is for.

I'm in the weird camp of "measurements don't really matter much, and subjective impressions don't really matter much, most people fail blind tests between gear anyway." I just think that most of the things that both camps claim to be able to hear aren't even there. Human hearing just isn't that good. You can barely hear -60 dB of distortion outside of test tones, let alone -120 dB. So when people tell me that their modern, non-faulty amp changes the staging, or that -140 dB of jitter is audible (which does not manifest in audible time-domain differences, it causes extremely minuscule Doppler Effect changes between samples, AKA a very slight frequency shift), I just kind of roll my eyes.

Any academically serious analysis should ideally include a "tech file" defining the test procedure and configurations used. We are proceeding incrementally, measuring becomes more useful as accepted practice evolves for the better.

What did you think of the yggy?

Highly informative video, so well explained. So the next question is: how do we measure things the APx555 analyzer is not able to test? Can it tell us everything we need to know about timing, spatial cues, separation, sound stage and other aspects about how the human ear perceives sound? Perhaps it is technically impossible to do so yet, but a wider range of testing seems to be needed.

Excellent!
