Just wanted to share my impressions with all of you.
I finally jumped on the bandwagon and got a pair of D-Sonic M2-1500M monoblocks.
The thing is, I put together this new system just for stereo, so I cannot compare the changes that the amps would have made to any previous chain. The system currently consists of: Oppo BDP-105 + Marc Audio XLR Premium interconnects + Two D-Sonic M2-1500M + GLS Audio speaker cable (12AWG) banana finish + Dynaudio Contour S5.4 speakers.
I am very pleased with the sound of the system, although the room might be tricky because it is roughly 7x5 meters, with a semi-wall in the middle (a 2.5 wall along the 5 meter axis). Very good bass response, no need for subwoofer, very detailed, good transients. I think it is not as forgiving with bad recorded music. Just about 30 hours of use, though.
Feel free to submit your comments and/or questions.
Cheers,
Carlos
