Here is an update on my journey of discovery about the merrits of MC.
Yesterday out of the blue I got a phone call from a friend (a 2 channel man) to come on over to his as he wanted me to listen to something special. A long drive followed.
He also used to have a HT in the basement for his son. He has moved out and the HT went with him. So when I got there, my pal showed me what was now in the Basement. A MC system, set up for music only, on 30 day home trial. The kit list is as follows:

Arcam DV137 Universal Disc Player
Arcam AV9
Arcam P1 Mono amp x 7

KEF Reference 204c x 1
KEF Reference 205 1 pair
KEF Reference 203 2 Pair
KEF Reference PSW400 x 1

Can't recall the cables.

I really wanted to experience the viability of genuine high-end performance from a multi-format, multi-channel system - something I had yet to hear. Well, I have now. I enjoyed it - never thought I would say that.
He had a couple of classical discs there and Peter Gabriels -Play. A recording I know inside out and a tour from which it came I attended. I just wasn't prepared for how good it was. This is one MC system I would be happy to live with but (there had to be a but), when it came to play 2 channel or 2.1 only it didn't sound as good as my dedicated 2 channel set up.
So if all my records could be in MC I would have no hesitation in investing in such a system. I can only imagine and dream what 7 Tube mono amps and ART Emotion Speakers would sound like.
On a site note I reckon that many HT/MC system are optimised for movies and that will have a negative effect on the musical experience I am sure.
Only got back this morning. Listened almost all night there.

Peace
