Stereo or monoblocks

Agree with the earlier sentiments. Assuming you have found a stereo amp you already like, if you upgrade the set-up to mono w/the same type amps...prepare yourself for even more music.

@normantaylor Since you went from 450wpc to 2000wpc, isn’t it possible that’s the reason for the improvement you described? It may have nothing to do with mono vs stereo.

+1 for the MC 402, been using for 20 years with LS360.

I started out with the Mc462 and then went with the C2700 pre and 611 mono blocks. Will never go back. Yes it is expensive but when the boss says it is ok, you do what the boss says...!

@chocaholic I know the increased wpc had everything to do with why my music sounds better on my system.  The mono blocks in my case provided greater wpc.  To your point, I have seen mono blocks that have quite low wpc, but I think that is the exception.
