Let's see YOUR system, Sandy

 My system is mainly DIY, and the internals as well as photos of my DIY Preamp etc. have been posted on numerous occasions already. These days I listen mainly on headphones due to other family members working mainly night shifts

Attached is an internal photo of my DIY Class A Preamplifier and 15W /Ch. Class A Amplifier. which like the rest of the system is Direct Coupled. i.e. NO capacitors in the signal path. They also use external toroidal transformers in a separate 2 rack case for best noise performance.

 Once again, that is rubbish. Dips and peaks in microphone response and positioning as well as limitations of the recording, especially from YouTube videos with heir compressed and low bit rate recordings make this a pretty well pointless exercise for the normal person, and this particular subject is best discussed in one of the threads that you have already started on that subject..

Please be consistent. There are many recordings which claimed to be the accurate sound of the original event. You can also read many comment it’s claiming such recordings can reproduce the instruments and space where the original event took place. But when it comes to recording a systems playback, microphones dips and peaks suddenly incapable of making the true representation of the playback sound? How is it possible for the microphones to capture the original event accurately but not the playback?

A recorded capture of the sound of a system using microphones is a very poor replica of the original sound and only useful where the systems already sound very different. Even then......

 

We know that. But why?  All playback is a compromised representation of the original event. When you record them using the traditional method they are further compromised.

Rubbish

 I have been able to listen to some very high end systems that a small group of friends own, some on loan from the dealer, and with systems even worth around Au$100K there can be very marked sound differences, with all components including expensive speakers .

 The best sounding ones were in most cases readily identified by the group under non sighted conditions.

 

I don't read the Hi Fi magazines these days so I can't comment on what they publish.

 I do have a copy of the review from Stereophile  of my old Musical Fidelity X-DAC V3 ,which got great reviews and had much better than average measurements, but all 3 of us who purchased them were highly disappointed in their performance, and all of us made major improvements in the PSU area where it was powered by an A.C. wallwart. We all modified them to be powered by an external Linear PSU with greatly improved results. 

Ask Kal, who actually took part in a proper blind test at Harman. The best you could do is to tell one is better than the other. For an example, if you were to compare Wilson, laptop and Sharp system. You could tell the difference.  But if you were to listen to Utopia, Wilson and the McIntosh, the best is you could only pick one that is better to your ears.

 I am being consistent. I find that recordings of performances captured in a room  from a pair of speakers, and then posted on YouTube are damn near useless for most purposes !!!

Why ? Is his hearing and equipment any better than that of the rest of our local group including Audiophile Neuroscience who has a well implemented system, and listening room ?

 Just because he writes for a magazine does not mean that his views are  more worthwhile than any other experienced Audiophiles .

It is the same even If you capture a world class live concert hall performance and post them via YouTube. It will be a compromised version. BUT only a deaf would unable to rank the performance and SQ even with YT quality.

Side-note, mildly off topic, but statement of fact  -- a lot of the commerical recordings on YouTube are infested with missing DolbyA decoding...  Just FYI.  I can clean many of them up A LOT, but of course usually only starting with 160k or 128k opus type source.

 

If someone masters their own material, of course the DolbyA problem won't exist.

John, I don’t think they still use DolbyA for recording nowadays. I could be wrong.

 Yahoo Serious ?

Systems with subtle but worthwhile differences will never be accurately captured for listening to crappy YouTube Audio.

 Of course, if you are capturing Frank's laptop speakers vs. any decent system that will be a different matter.

which headphones?

 It looks nice, but what is the source of the music, the type of amplification etc. ?

 No, you don't come remotely close to the vocal members that I am referring to .

QNAP NAS, MacMini/Roon, opticalRendu, PS Audio DirectStream DAC, Audio Research Ref 3, Audio Research Ref 75SE, Wilson Sasha II’s, wire by Audioquest except for Curious Cable USB.

They are very useful, because they make it trivially obvious when the playback has significant issues - you see, you're not trying to determine how good it is; rather, you're wearing the cap of a troubleshooter - there are very few videos of good sounding systems on YT ... because, well, they are not good sounding in the flesh, 😉.

Audio Technica ATH-M70x are the best I can afford these days after an earpiece went o/c in my original ATH W1000
 with Bubinga wood cups, which were way more expensive, and had a thin layer of butyl applied inside the cups to reduce resonances.
 They have an extended frequency response to 40kHZ (no details provided), and have a flatter frequency response  than most headphones in the critical VF area.

As an example of what can be conveyed about replay in a YT, a solid effort that came up some time ago,

Massive spike in the response around 10kHz - no wonder you like what John Dyson is doing to tame the HF stuff ... 😀

Bullshit !

 Have you checked out the Frequency response of most pairs of headphones ?  Many die in the arse just around the 9-10kHz area .

Do you think that nobody else except  yourself is capable of taking into account things like this , which are also later compared by me via the main system where there are no such anomalies, and the DAC is of an even higher quality ? This is trivially easy for me to do because all of John's samples are saved to USB memory stick initially..

 What's your excuse where you prefer the accentuated HF response of the non decoded Dolby A original recordings ?

Do you know why it is even posted in YouTube?  Or is it just a convenient excuse?  How would you propose this comparison be done?

the ATH-M70x  do look real hot at 10 kHz

Have you checked your ears Frequency Response?  Do you even know why they are steeply attenuated at higher frequencies?

Maybe  there is a reason why he is hearing difference under extraordinary circumstances.

Take it easy, Alex, I was taking the pi.. 😄

 

What's the magic problem with headphones, in the 10k area, anyway?

 

You know I'm taking this Dolby A thing with a huge grain of salt - there are plenty of recordings with balances which provoke the replay chain into sounding unpleasant - this current laptop of mine, with 'micro' speakers, is no different from everything else out there. Which is why I'm using my CD rip of Ring, Ring to 'troubleshoot' - in non-optimum status, very screechy; and this steadily disappears as I get closer to better settings for everything.

 As I previously stated I have a way better than average main system where I am readily able to confirm my initial impressions.

 This thread is getting beyond a joke.

It has developed into the usual  Audiophile bashing thread and personal attacks.

 

 John Dyson trusts what I report,  as does Barry Diament and Martin Colloms, and on several occasions cases I have referred the tracks in question from John to others for their evaluation.

On all recent occasions they have agreed with me. One is a Professional performing Classical musician.

it is becoming a joke when one posts picture of inside preamp to prove that his system superior to others. I have seen thousands of them. What matters is what comes out of system and reaches your ears. 
 

So what would be the alternative to YT?

None of that matters based on your equivalence of all personal experiences argument
