The M3A is a full tube preamp. The SA-3000 is a hybrid. I have owned both. IMHO, the M3A kicks the crap out of the Counterpoint. Just my opinion of course...
Counterpoint SA3000 vs. Audible Illusions Modulus 3A
I'm trying to decide which of these preamps would match up best to my McCormack DNA .5 amp? My current speakers are Magnepan MMG but am looking to move up in the Magnepan line. I listen mostly to vinyl and stream Title.
