Good clean sound but not that perfect what I expected for my 6XX after reading description
Setup: Tidal (MQA) on Mac -> iFi iDAC2 -> RCA cable -> ZEN CAN sig 6XX -> balanced cable -> Sehn 6XX
Music: jazz and classical (mostly piano and guitar)
Clean sound but pretty flat for my taste. I got much much richer, deeper, and wider space on Drop's Cavalli Tube Hybrid Amp, without loosing clear crisp sound, hands down.
