After hankering after the Tannoy Arena and Kef 3005 "lifestyle" speakers, but rejected teh Tannoys for their mounting issues, and the KEFs for their possibly-questionable performance issues, I have abondoned the idea of lifestyle speakers and have decided to stick with traditional wooden boxes. I have decided to go with Tannoy Sensys DC2 with teh equivalent Sensys centre. Is there anything wrong with having them for both fronts and rears? Only I listen to SACD's and they recommend identical speakers all-round. The reason I ask is, 5.1 traditional design speaker packs with floorstanders always coem with bookshelf speakers at the back. Thanks.
