Has anyone heard the Lexicon MC-10 processor and can they describe its characteristics.

Yeah @motogp tell us the verdict..

Here is an update from about a year ago, its a long story.
I purchased a Lexicon MV-5 as an substitute while my Krell was sent to the Krell headquarter for repair.  My audio technician and installer sent a detailed mail to Krell outlining every issue with the Foundation.  Krell called back and said they felt the 4K was performing properly.  There was no addressing the list of issues provided to them.  The unit was reset to factory standards and returned and set up in the system.  It performed as it did before it was sent to the Krell headquarters.  In other words, the base/subs play sometimes, not all the time.  Most of my music is streamed from an iPad to Apple TV.  While listening, and without warning, the subs will start playing, like the volume for the sub was turned from 0-10 blasting you out of the room.  The subs will play for 3-5 seconds then stop.   Other times, they will play for the entire song.  
In the meantime, I tried an Arcam AV40.  The tech/installer and I auditioned a few songs and videos, then went back to the Krell.  The Arcam video and sound were disappointing and underwhelming compares to the Krell.  I just wish that I could get the Krell to perform properly, when it does, it's exceptional.  The subs are top of the line B & W.

I have an MC-10 that replaced an Anthem AVM 60.  Firstly the AVM 60 was a great processor - no issues here.  That being said when I hooked up the MC-10 there was material improvement in sonics primarily detail and spatial imaging.  Bottom line is the DACs are top notch and better than what was in the Anthem.  The Lexicon costs more and you get what you pay for.

Aesthetically looks are great but who really cares.  The user interface is boring and the graphics looks 20 years old but again who cares.  Sonically in its price range the unit is elite for movies as well as 2 channel listening for a HT processor.  It was lovely with my Raspberry Pi streaming Tidal MQA.

Everyone is correct its based on the AV 860 platform but that was one of the best sounding processors Arcam ever made that puts the replacement AV40 to shame.

I suspect it best the AVM 70 and you would likely have to go to the AVM90 to get DACs that would compete or best the Lexicon.

I’ve recently went to a Datasat LS10 and may be listing my Lexicon shortly.  I acknowledge that my comments above are self serving however my comments are true and sincere.
