I would actually replace your preamp before replacing your amp. There are MUCH better preamps out there for similar dough than your M3A. In fact, I purchased a cj PFR which, in my opinion, blew away the M3A in tonal accuracy, rhythm and pace, and most of all, musicality. Keep your Bryston; get a new preamp instead.
However, if you are convinced about replacing your amp, the GamuT wins in my book. The Plinius is second. Both these are very musical amps and neutral to the source.
Good luck.
