The guy has problems, for sure. He sees fairies and magic dust everywhere. Most odd.

So let me get this straight, you have a DAC and a Streamer-Server that only has USB that is bad? That using a USB cable from a company like DH Labs is foolish even though the cable is not that expensive. That the DAC and the Streamer builder are not using 5v protocols, it is still bad even though the DAC and Streamer engineers built their respective devices around these  protocols. Please explain this to me @tvrgeek I must be stupid. As must these engineers at all these companies. 

USB is the defacto-standard. Anyone who wants to be in the marketplace needs to follow the market trends.  It is not the best transport, but it is what we have. 

PCM, coax or fiber, relies on the HOST to providing clocking information. Notoriously poor. USB uses the DAC or STREAMER internal clock. It can be as good as the designer wants.  For $100 it can be excellent. 

Some new higher end DACs also buffer and re-clock the PCM, so it would them be just as good as the USB Mode 2.   

Stupid engineers? Yes, if they do not design their interface to deal with the realistic world.  An AMD galvanic isolator is a 50 cent chip, yet why don't $5000 DACs include one? Incompetence!

I will say ONE MORE TIME, I measured the noise injected into the analog output using "free-be" cables which cut open were very poorly shielded. I measured none with well made to spec.  I measured none using a $12 external galvanic isolator. 

Just trying to provide factual information.   Not everyone has a technical background so they may be more susceptible to snake-oil or may more easily fall into placebo conclusions.   A little knowledge helps.   

If someone is not interested in factual information on this subject, you do not need to read my posts. I  try to present facts so people can make up their own mind.  If you have any actual evidence other than "You believe", please present it. 

I hope a $90 USB cable is well made and works as well as a $6 one that is made to spec.   If you feel better using it and can afford it, fine.  Just understand it does not actually perform any better.
