USB "A" and "B" to RCA adapter


I'm seeking adapters to convert standard USB cables to RCA interconnect cables to obtain a more thorough burn-in via normal Line Level inputs/outputs vs the low output of a PC software player to better exhibit our YBA DAC modules in preamp/DAC products.

USB "A" to RCA
USB "B" to RCA

Any suggestions will be most appreciated....thanks, y'all!

"Audiodharma make a suitable set of adaptors (RCA to USB) for use with their cable cooker, and while you’re at it might as welll buy the cooker as well, it is well worth the $"

Are you sure? An RCA cable has 2 conductors and a USB cable has 4.


Presumably the adapter splits the one USB to two RCAs hence four conductors?
The adapter could simply use the 2 data lines and not the 2 power lines on the USB cable.
