Thanks Norseman....still have not pulled trigger on this because i keep reading issues on this unit. My rx-665 just works without dropouts ..volume changes.. etc.
Then I'd just wait a while longer for the Emo XMC-1 to finally come out, and watch the user reviews very closely. Its projected to have a great price, and should avoid most of the teething problems the UMC-1 has had, (but are now mostly resolved).
And on the other hand, for every complainer about the UMC-1, there are likely 20 others who are happy campersthat we never hear from. Because as we both know, people are far more likely to complain (or protest! ;-D) when they don't like something, but we never hear from them when everything is working well. Just human nature...
Bottom line: don't be in a hurry - and good luck in your ultimate selection!
