I am considering upgrading my Denon receiver as a mate is looking at getting a home cinema system and it will be a good start for him. I am not sure if I need to go for a receiver that decodes the new HD formats or not. I will mainly use it with PS3, sky+, and my HTPC (optical connection) I am currently considering getting one of the Onkyo receivers, or possibly a slightly older higher end system like a Marantz SR-8001. It will be partnered with Monitor Audio silver series speakers. Also, what would be a fair price for the AVR-2805?
