I am selling my Schiit Bifrost DAC with Uber Analog Upgrade, Gen 2 USB Input and DH Labs Ultimate RCA jacks, which are gold plated pure copper and wired with Neotech upocc copper litz wire. I have the stock analog board and Gen 1 USB board to send with the DAC if you want them.
The DAC goes for $519 and RCAs for around $90 (it's been a while so I may be off a little, but pure copper RCA jacks are not inexpensive). I can't find anything at all wrong with it in appearance or function.
Asking $400 Shipping and Paypal Included.
