I've been lamenting a new pre/pro and amps. I have hunted around for a a good sub $4000 pre/pro that offers the same features as the Denon 3803 in my bedroom and I am having trouble. Some do but then you read comments about reliability, or hum or whether the company is likely to be around in 2 years. I'd like to hear comments about people who have used say a 3803, 4802R or 5803 or any receiver as a pre/pro with external amplification. I have a full large NHT speaker system which likes warm sound from the pre/pro but a lot of juice from an amp, which I don't think you can get from integrated.
