Query: amp leaves much to desire / Customer service nightmare

This A/V receiver arrived with a remote control that does not work. The auto set-up works OK but it thought I had large front speakers when there small, so it configure the sub-woofer too light. When playing DVDs with my new OPPO up-converting DVD player it would loose the center channel. I would have to go into set-up to get the center channel back, (bear in mind all of this with no working remote). When trying to get the remote replaced under warranty you can forget about being able to speak to customer service by phone, you will be on hold permanently. When you get someone to respond to an email you can understand why they dont answer there phone as english is likely not there primary language. The person I dealt with was clueless and unprofessional. I don't need this kind of aggravation after spending all the money for a good receiver. This ones going back, and I will never buy Denon again
