Currently running an Infocus IN76, picture supplied from either Media Centre XP or Sky+ (currently deciding between PS3 or XBOX with HD). All I have for sound at the moment is a pair of half decent Sony Headphones. Loft Conversion is about 3.2m X 5.5m. Looking at installing a 5.1 system. Plan to spend about 600quid. Was thinking about the entry level Onkyo or a Dennon at about 250-280? Some of these amps come with HDMI switching and upscaling, is this any good? (is it possible to switch analogue signals to HDMI too? This save running loads of cables to projector. Was thinking about Kef Cresta 3s for front prob biamped if amp is 7.1, mate mentioned these are a really great speaker for the money. The Kef Cresta for the centre and maybe another pair of Cresta 3s for the rear? Would leave some cash for a smallish sub or get a good secondhand one here cheaper? Ive had a look at the all in one packages but dont like the look of the small satellite speakers. All Help appreciated, not really got a clue on what would be best.
