I had a Denon 4800 until it recently broke down. I am looking to replace. Figure my budget to be around $2000. What are some suggestions? It will be used mainly for home theater, but do appreciate good sound when listening to music. What are some good options. I may be able to push the budget up to $2500. Using Paradigm studio series for speakers. I'll also look at used options, but prefer new. Thanks.
