I've been out of the 'proper' home cinema loop for a few years now (which is why I now have a wife-friendly 'all-in-one' system), but I could do with some opinions/advice on my current proposal. I am thinking of converting the loft into a dedicated home cinema (approx 12' x 16'), and I've got a Yamaha RXV795, Kef Q35 speakers, Kef Model 90 centre speaker and a REL Q50 subwoofer gathering dust at home. If the conversion were to go ahead (need to put a 'business case' to the wife!), would look to spend approx. £1000 on a new amp/receiver - current thinking would be something like the Yamaha RXV4600 (I like Yamaha having had a DSPA590 in the dim and distant past), but I just do not know what to do about speakers. As it's very tempting to spend money on new kit, my initial thought was to invest in something like the M&K K series, particularly as music isn't a priority. But, would I better off utilising my existing Q35's and Model 90 and adding to them? If I were to get a new speaker package, the budget would be £1.5 - £2k, but I don't want to spend for the sake of it. Does anyone have any views or opinions as to whether I would be better served sticking with Kef and using part of what I've got, or would I regret making the compromise, and would I get much better performance with something else? Also, is a 6.1/7.1 speaker set up significanlty better than the standard 5.1? Cheers.
