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

Well we will find out together . I just ordered one. I am replacing a Marantz 8805 that is currently in service. Initially , I just wanted to try Dirac as I keep hearing how much better it is. I did some research and every person I talked to said I was in for quite a surprise. Audio Advice, which sell both the units , told me

"The 8805 isn’t in the same class as the MC10. Like Comparing a Ferrari to a Honda Civic."  

Here's a little teaser ...

I appreciate your response.  I auditioned a Marantz for about 6 weeks and was counting the days until a replacement could be found.  It was harsh, cold and unmusical.  The Video was great, but I could not get past the sound.  I am waiting for Krell to repair my Foundation and have purchase a used Lexicon MV-5 to hold me over in the meantime.   My AV tech installed it this morning and the sound is awesome after listening to an ailing Krell for a month.
Good luck on your new purchase, I look forward to hearing your assessment.

@erik squires - the mc10 is the latest unit from lexicon makes zero sense (to me at least) why they went the opposite direction with the model number. 
I too am interested to hear about the lexicon.  I have an 8802A through Lexicon RX-7 Amps to Revel Studio2, Voice2 center and gem 2s w a pair of F212V2s and I just can’t get things to sound ‘right’ especially in the center channel it just seems so laid back. I don’t love the surround modes on the marantz either they can do weird things and the sound just feels off sometimes. Unbalanced. I like the voices  better from my other setup (marantz 7007 and pioneer elite Andrew Jones setup) which altogether cost less than the Voice speaker alone!

Has anyone demoed the mc-10 yet?

I have not but have an MC-12. I only responded because of a comment around remotes- a Logitech remote can be programmed to drive the MC-12. Good luck with the 10 if you decide to go that route. The 12 is exceptional.
