In Reply to: RE: REGEN adds measurable noise.... posted by AbeCollins on May 23, 2016 at 09:10:07
According to the lengthy and horrendous thread, the noise only appeared on the output of the DAC when the analog connection from the DAC to the analyzer used unbalanced connection. This proves that the problem was between the DAC and the analyzer or was, in some way, an artifact of the experimental setup.
There is plenty in the thread that demonstrates technical incompetence, not to mention toxic personality.

Not only technical incompetence at the experimental level but also complete incompetence in understanding how asynchronous USB works & attributing this lack of understanding to John Swenson.He states that these are Swenson's two theories behind the operation of the Regen & tries to say that Swenson told him this here where his arrogance is palpable http://www.whatsbestforum.com/showthread.php?20641-Sonore-s-microrendu-is-out-the-first-audiophile-microcomputer&p=394601&viewfull=1#post394601
{quote}"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."
{/quote}Anybody who knows the first thing about USB audio would know that asynch USB has no retransmission function & to state this & attribute it to Swenson shows both complete ignorance & extreme arrogance - Swenson does not suffer from such ignorance
His next uninformed target is the MicroRendu which he again fails to show any technical understanding of it's operation

"His next uninformed target is the MicroRendu which he again fails to show any technical understanding of it's operation"
And it didn't take long for this embarrassing thread of his on the MicroRendu

So many USB filter devices and I don't even have one yet. If anyone is doing a showdown please post it.
that thread over at the W'sBF was like watching an episode of The Outer Limits with a science guy not only narrating but playing the main role.
A self appointed judge, jury and executioner.
