Title: USB power for DAC
Post by: whatcomfalls on April 12, 2015, 02:16:09 am

Least invasive method for experimentation is to sever the 5v power wire by covering the 5v pin on the USB cable A connector with tape. It's what I did---I noticed no difference in Sound quality. I am however using a linear power supply for Id which improves SQ compared to the stock NUC switching power supply.

interesting.  did you feel the linear power supply improved the sound?  Which supply are you using?  I really have no complaints about the sound, was just curious if the potential existed to cut the 5v at the USB port.  thanks.

Linear power supplies I've used are Acopian 12V/1.2A and Condor 12V/1.7A. Both "sound" better than stock PS, IMO.
