A while back, I heard the ME amps at several Melbourne HiFi shows. They were nice sounding amps but somehow I was never really impressed. Subsequently I purchased the Plinius SA100 mk3 which was clearly superior to my ears. The Plinius served me well until I A/B'd it at length against the AKSA 100N+ in my system and found it couldn't match the AKSA.
While it seemed strange to replace the well known and acclaimed Plinius (Stereophile class A) with a relatively unknown and much cheaper DIY amp, my ears, my tapping foot, and the grin on my face made it an easy decision. The Plinius had been a significant improvement over the Rotel 125w monoblocks I had previously and the other amps I had compared it to (Electrocompaniet, Arcam, Musical Fidelity, Perreaux, etc).
To try to put it into context, with relative scores out of 10:
Rotel monoblocks = 7.5/10
AKSA 100 = 8/10
Plinius SA100 mk3 = 8.5/10
AKSA 100N+ = 9/10
