This might be a stupid question but since there's both a 3.5mm and RCA out. Is it theoretically possible to run 2 headphone amplifiers with this ODAC at the same time? Would be great if I can do that and share music with someone beside me at the same time!
AkumaKuronoYup, that works.
Another way to think about it is, if you have the original O2, use the 3.5mm output on the ODAC to connect yo your O2, and use the RCA output to connect to a pair of powered speakers (Kanto, Audioengine, Swan M10, whatever).
