You specifically stated
here & not on ASR "I have managed the development of full computer system including design of VLSIs that go in them."
So back up your claims here & show you have the engineering chops to state that John S theory is flawed or not
Again John, you are an IT person. How would you remotely be able to judge my and John's hardware expertise? Reading stuff online would not at all prepare you to understand any such answers. You don't even know how to ask the questions properly. It would be like you trying to challenge Steve that he is not a qualified doctor compared to some other doctor.
As I said, I would love, love, love to take you on because I know you well. I know how you debate. I know your skill level. And I know it would be fun to do take you on
. But as a site co-owner, I just don't want to take this thread down into the gutter this way.
If you really want me to do it here, get Steve to bless it and I will do that against my better judgement of what is best for the forum.
You are wrong about your arguments anyway as I pointed out to you:

"My day time career though was managing
hardware and software development of computer system. As much as I loved computers, I wanted a way to get into audio as a profession some how. Went to work for Sony but that turned out to be managing design and
development of operating system and computer hardware down to chip level."
No different than what I have said here.
Again, trying to deny what you said
here " A flawed theory" So tell us how the theory is flawed, not it's implementation - you know, educate us about ground bounce & ground noise.
He had two theories:
1. That a degraded USB signal causes the receiver to ask for retransmission of USB data. Therefore he thought by strengthening the USB signal through a Hub chip, would help. Well, that is not remotely a problem with our short USB connections. Data gets to our USB devices just fine, thank you very much. When I met with John, I asked him how often that was happening and he said it was not because it looks like newer USB silicon does not do this anyway.
2. The general lay notion that less activity is better. I explained to him that a periodic 8 Khz timer event is far more harmful than tons of activity because the former will stick out like a sore thumb in the forum 8 Khz jitter, or reference modulation and hence be more audible. Whereas random activity would just raise the noise floor which published listening tests show to be far, far less audible. Of course, both of these assume that such things are a) improved though his device (which they are not) and b) are passed through by the DAC. Without having measurement equipment he would simply be in the dark with no means of seeing if his theories are right.
Audio Precision was at the show and he and his partner talked to them about buying a new. But when they found out even discounted price is $25,000, they said they could not remotely afford it. And that was that.
Actually that was not that. I offered to do the testing for them to fix the new distortions they were adding to USB. They said that would be hard since John lives in Silicon Valley and I am in Seattle. I told them my offer stood if they ever wanted to take advantage of it.
