UpTone Audio USB Regen Listening Impressions

[all300b]

Hi Barry:

 

The REGEN ignores any incoming voltage on USB pin-1--it is not connected to ANYTHING on the board. So any audible benefit of having a USB cable with no 5V coming down its length is NOT from keeping 5V out of the REGEN. Rather it is that you are reducing any capacitive coupling of the voltage to the data pair along the length of the wire.

 

So yes, you can use an Sbooster VBUS isolator (or just tape over pin-1 in the 'A' plug at the computer end) and thus have a data-only cable.

 

 

So you can still get coupling over the length of the wire even if the 5v line is disengaged on the receiving end?
