About the time this thread began my UMC-200 bricked on me. On start-up I got the loading.......... message.
I kept quiet about it; didn't post here or on emo's site. I called tech support at Emo and after just a few minutes of waiting, and explaining the issue, was given an RMA number. I did need to check back with them later in the day, as I had not yet received the Email explaining the return terms. Lonnie himself actually answered the phone. In my conversations, the people I talked to were polite, but obviously busy, and maybe a bit stressed.
On Wednesday of last week I sent it back. They received it on Friday. On Tuesday afternoon of this week I called to check on the progress and was told "they are working on it now".
Of course I thought, sure they are.

On Wednesday morning I got an Email requesting confirmation of my return address.
The unit was shipped out that day, and I received it today, Friday. I just now got it up and running.
Not bad customer service IMO. Total down time: 10 days
Compared with companies like Sony, Yamaha, Denon, etc; Emotiva is a mom and pop shop. They certainly don't have the R&D budget of the big boys. You get great product, albeit with the possibility of issues, at a good price.
For me; the issues (well documented on Emo's own site) vs the cost and quality of the final product... pfft... no brainer.
Call me a fanboy. I'm sold on Emotiva.
Just thought I'd throw my 2 cents in here.
