Experience with Simaudio Moon North amps

@dpac996 The 760A was just as revealing on my system but I have perfect hearing. It just didn't have the 4 kHz to 6 kHz emphasis, also known as presence. Simaudio over-boosted the 761, leading to a harsh or sibilant sound at times. They punched through Sonus Faber Serafino G2's and were matched with Octave, Mola Mola, and Bryston pre-amps. Regardless of the pre, they were always artificially lively.

Glad they worked for you. I found them inferior in design and performance to the 760A.

I ran the 761 for a month and returned it.  IMHO, it had an upper mid-range frequency emphasis that made it lively but much less warmer than the 760A.  I preferred the 760A sound paired with a Mola Mola preamp. The presence of the 761 makes sound stand out and feel more real or "present" in the mix but definitely colors the overall sound, and not in a good way IMHO.  I'd recommend an old 760A over the 761.
