Firstly I have an MC1 for sale in the classifieds - so you can take my coments and advice at face value as intended or not as you please.
The MC1 is in my onion a truly fabulous processor I have read posts from people who prefer it to the MC12 !! mind you as it was £5000 at first launch nearly 10 years back it should be something special. I think it is still well ahead of all but maybe the most expensive top of the range Japanese stuff and at current prices is an absolute bargain.
It sounds fantastic on AV and has so much flexibility in set up
Ok Stereo isn't its strength but if you use the expansion ports and by pass the processor the problems only really surface with high end amps and speakers
Expansion Ports - yes - well ahead of their day and meridian use some thing similar too - more of this later
Yes as far as I know Shawn Fogg still offers the 7.1 channel by pass installed for very sensible money or he will sell you a kit to DIY.
Lexicon 8 channel analog bypass input
A forum member used to offer the same in the Uk but his site is down these days so I guess no longer - if you search on here you might find contact details. He was expensive though.
Interestingly Shawn Fogg also offers these
3x S/PDIF Transceiver (In/Out)
which you could ad to the sources and send 5.1 digital, direct the the front rear and sub dacs all via the expansion ports
Using the expansion port for the front channels - ie using the MC1 as a DAC is pretty good and far better, for music, than routing through the DSP options
the other thing worth thinking about is getting an HD player like my XA1 that will output a 1.5mps DTS sound track - The lexicon really handles this well and I am sure it will be far better than any run of the mill HD processor. It is a significant step up on SD audio
