I know it's an integrated amp but being Lexicons new toy i'm sure it's quite a good one and at £5,500 i think belongs in the Pre/Pro/top end forum. It looks like an MC-12 face on a 7 channel power amp. Check it out at lexicon.com and wait for the glowing reviews. At this price you could get a seperate pre/pro but looking at the specs, 2 hammerhead processors etc, it doesn't seem too bad.
At the moment, it appears to be more of an MC-8 melded with a CX-7 amplifier and apparently this thing is huge!
