I've got CM7's and have an unusual setup. For 2ch, I use the NAD M3 Master Series amp running Discovery Essential Speaker Cables with good quality banana plugs. When I want to watch HT, I'm using an Onkyo Receiver, Discovery 123 Speaker Cables, CM Center2 and B&W Side Speakers, no rear. I wanted to keep everything separate so I just swap speaker cables when I want to watch movies. I also have the CM10 sub but the CM7's have enough bass for 2ch so it's only used for LFE.
Front end is Cambridge Audio, Auzure 840c, Bryston Dac, Discovery Essence Interconnect and Kimber Silver digital.
Everything is setup by laser for precise imaging,even 1/4" misalignment of toe-in and distance to my ears make a huge difference.
Speakers sit on Mapleshade Wood with brass under the speakers, tilted back for time alignment, and Heavyweight Brass spikes into the carpet.
This system images like $10,000 speakers for much less money. Setup is critical, they need lots of room behind the speakers, toed-in so the tweeters cross 12-18" in front of my nose. Time alignment is done by assuring the distance from my nose is equal to the tweeters, midrange and woofer. They create almost holographic imaging with this setup.
I'd like to re-wire the CM7's so if anyone knows anything about wire mods or crossover improvements, please let me know.
