I have £2500 to £3000 to set up a home cinema (with projector) from scratch. I'm undecided about nearly everything but on the audio side I'm thinking of a Denon AVR-2105 amp (on the basis of a good review in November's Home Cinema) and the Acoustic Energy Aegis Evolution 3B 5.1 package (which several places have on offer). My only concern is that this set up may be too powerful for the room, which is 12 feet wide and 14 feet long. Ceiling height is 8 feet. Any thoughts?
