Well, just got a new one of these and it's already stopped working within 45 minutes
It still works with unbalanced DAC sources. However, simply cannot get any sound out of it now through ANY balanced source. It was using SDAC-B initially when it stopped. Works from the single ended connection on the SDAC-B though, and 2 other DACS I tried. SMSL-SU8 same problem. iCan was set to balanced each time.
Anyone have any idea of further trouble shooting? I even tried 2 different sets of balanced cables, both of which have always worked with my 2 other balanced amps and did with this for 45 minutes. Tried shutting off and back on, SS, Tube, and Tube+, every gain setting and still nothing. I'd read that many others have had problems with them brand new but was hoping for the best. It seems very bizarre that it would work balanced at first and then stop working so quickly. Very frustrating!
