I am in the midst of a financial pitfall, so I must unfortunately "downgrade" my home theater, so to speak. I currently am running a Rotel RSP-1066 mated with a Carver 806x amp. I want to know this- are there any receivers out there that will provide comparable sound quality and impact? I am trying to stay under $1500, and will buy used if I must to stay under that level. Thank you for your input! Andrew B.
