Thanks, I should definitely try to build this one. I plan to use is as source for a SOHA I already finished (with crossfeed, custom built output buffers and Epsilon12 protection). Can I simply join the outputs of the Alien DAC to the RCA inputs of the amp, without fussing with input switch, or the Alien DAC will have a bad influence when not used on the RCA signal? I mean the CL/CR could play for both system, right? I don't remember if the SOHA has DC input protection, I should check that. What is the best choice for CR/CL (discussed at libitum, I know, but a resumé of all the thread would be nice) if I have to put them in? As I understand, the Alien DAC is producing DC offset that has to be blocked, internally, or by the amp, right?
I never soldered SMD, but am reading all tutorials available. Is it ok to go unregulated USB power? What should I expect in comparison with the stock headphone output of my Macbook (sound quality point of view, apart from the SOHA influence)?
All the very best,
