Am putting together a system, primarily for surround audio only, but will also use for home cinema. Any tips on the surround speakers for the following, currently theoretical, system? dvd/cd/sacd/dvd-a Pioneer dvd 575a or marantz dv 6500 receiver/amp - marantz sr7400 The speaker options are the following Kef kht1005 Canton ct1 Mordaunt Short Avant Premiere System Mission cinema m30 5.1 Another option is to use the eltax or yamaha ns10s that I already have as the front pair and add to that. If anyone knows of a shop in London where I could listen to these setups, then that would be really useful. Any advice gratefully received.
