You guys gotta understand the business and cost scope of this subject. I've talked about this before. Emotiva will fully support all of their products while in warranty. Their support is absolute excellent. You should try getting this type of support from Sony/Marantz/Denon, etc. on a receiver that is still in warranty. Those companies will just refer you to a certified electronics repair, but nobody want to work on that stuff because there's no real profit/return on those items from the Manufacturer. I'm sure Emotiva may even support some of their models that are out of warranty. You have to realize that you are buying a very low cost "excellent for the money" product. You are not buying a $10,000 amp from Bryston, ARC, Pass Labs, etc. etc. Those guys will support everything for ever, but you PAY for it.
Emotiva made a business decision to stop supporting their XPR line because of costs and the difficulty in just working on the XPR platform (believe me that I know how difficult this is because I have now rebuilt 4 XPR-1 amps so far). It's a freaking pain-in-the-XXXX. Even under warranty, customers would never ship their stuff using freight on a pallet even though Emotiva told them to. The amps being 100lbs would often arrived damaged and the heavy transformers are often broken loose. It became a lose-lose situation for them. Be glad that they are supplying full schematics for these amps (something that doesn't happen very often).
Just keep that in mind when you start complaining about Emotiva.
