I've had a mc-8 for about two weeks now and I must say thats its one fine piece of equipment. Prior to this I have had various pre-pro's dc-1,dc-2,mc-1,aragon soundstage, hk avr8000, various denons etc. Im using this in a 7.1 setup with 4 citation 7.3 dipole/bi-poles for the sides/backs set to direct bi-pole mode and nht's t5s up front in a 14X14 room and sit about 8 ft from l/r/c and 5 ft from each side speaker and 3 ft from the rears. Anyway last night I was messing around with the rear delay offsets listening to 7 channel music logic mode. Ive tried various setting and assumed that the largest delay of 30 ms would be the best for a small room. What I found was that after trying every delay from 0 to 30 that something weird happened at EXACTLY 12 ms.. The sound just totally clicked into place..stereo imaging behind me was right on and bass sounded like it was more distinct and coming from totally behind me. When I moved the delay just 1 ms to 13 or 11 it wasnt as good..I dont have a clue why everything is perfect at 12 but not 11 and 13 ? ..but it was easily detectable!..I havent tried this on movies yet but would assume it would be the same effect. There are soooo many tweaks on the mc-8 that you can literally make this processor sound however you want it to sound. You could spend months tweaking this bad-boy in. I was reading that other under 6000 pre-pro thread on avs forum and thought to myself that its actually a compliment to lexicon questioning its two channel performance...because there is no way in hell anybody could ever question its processing/ movie decoding abilities/ user interface/ tweakabiltiy etc..Can you imagine somebody saying " well the lex is pretty good in two channel but that logic 7 sure sucks"..That just leaves two channel performance as a crutch for lexicon's competition. Every product has to be attacked somewhere and the lex mc-8 leaves little to be questioned. Its like a fire-breathing dragon thats big and bad and smokes everything around it..but if you can find that one soft gill to thrust that sword into...you can slay it.
