Dear experts - I am agonisong over the above set ups. I have a pretty big semi conservatory/extension (18.5' x 15') that I have had discretely wired for a 6.1 set up (with 7.1 possible). ( I will only be using 2/3rds of the overall space for a home cinema set up). My dilemma is whether or not a room that size will genuinely benefit from a more expensive Denon 2805 or the cheaper 1905. Also would they both be capable of driving a full size speaker system such as the evo 3 b's, and conversely would the 2805 be a waste of time with the mission m30's ? Any advice would be apppreciated as I dont have an unlimited budget (havent bought the plasma yet) but I dont want to regret being too cheap later, and havent bought a decent set up for some years. Thanks.
