I am currently running a Synthesis Essence stereo amp, 25 watts from two pairs of 6l6/5881 tubes. It's on loan from Deja Vu in fact and sounds excellent powering my AN/J's. No personal experience with Coincident or the 27AC specifically.
Synthesis 27AC vs COINCIDENT DYNAMO 34SE MKIII
Ok, this is getting pretty esoteric since Synthesis are Italian made but has anyone compared these two amps? The Synthesis is 25 watts and the Coincident 8 watts but I will be driving very efficient speakers so if anyone has any thoughts on these two amps, especially if you have compared the two, I would be open to your thoughts.
