Stereo or monoblocks

 look a great stereo amp builder is already doing dual mono in same chassis… except IF ya implement it correctly speaker wire L goes down massively…. That’s the KEY….

by implementing mono blocks w < 30” cables…..

A little late on this chain, but I recently changed from a stereo amp to mono blocks. I have power hungry Magnepan 20.7's.  I had a McIntosh 462 stereo amp that supplied 450 wpc.  It worked well.  However, I decided to go mono blocks more out of curisoity than anything.  I bought Sander's Sound Systems amplifiers.  Magtech Monoblock amps.  They supply 2000 wpc!   I was blown away by the difference in clarity of sound.  It made my Maggies blossom.  I even contemplated selling my REL subwoofers because the bass was coming out of the Maggies like I had never heard before.  In short the amplification of the mono blocks was remarkable.  I am a believer in mono blocks.  I heard instruments and sounds from CD's and LP's I had listened to for years that I had never heard before.  It was truly amazing.  I am a big fan of Sanders Sound Systems amplifiers.  Roger Sanders has been in the biz since 1974.  As an engineer he is meticulous in his work, has written many white papers on audio issues and has top service.  Best of luck in your adventure.

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.
