Looking to Purchase the Dennon amp to Run home cinema system. Romm is attic conversion about 5m x 3m. Running INfocus IN76 for picture. Mate keeps banging on about how good the Kef Cresta 3s are so was going to get a pair from the front and another for the rear. (amps 7.1 ro poss biamp the fronts. Also get the Kef cresta centre for centre speaker and I've got to find a suitable sub for around the 100pound mark. Would this be reccomended? Looking at reviews the Kefs were really good speakers when released a few years ago so great value for money. Am I also right in thinking that the Dennon can switch composite video? (if it can will it accept RGB from sky+?) Going to head into Richer sounds tomorrow for a listen so any info before then would be great!!
