Oppo 105 Updates!
I have a working prototype using four out of the eight DACs on the SABRE chip. It sounds fantastic via XLR and RCA, USB in via J. River Media and on all disc formats. The proto includes the new power supply design with tube rectifier and tube regulator tubes.
Next step is to incorporate the remaining four DACs in the tube circuit and in turn, allow for upgraded HP performance as well as standard playback performance.
Further upgrades to test in, include silver wire, Tantalum resistors and dialing in tube bias (operating point) of tube circuit for ideal synergy.
I am also going to examine the possibility of replacing the SMPS (Switched Mode Power Supply) with a linear supply of our own design. I already have a proto PCB built and assembled for the 103 PS and am working out the final details.
Just wanted everyone to know where we are at.
