I've currently got a pair of B&W 685 which replaced a pair of B&W 602 S3. Amp Denon AVR 1911. I'm thinking of getting some floorstanders for extra woomph. I was thinking of some B&W 603/4 S3 or 684 which I could pic up for £300(my speaker price + not a lot more ££) But I've read a lot of reviews saying the treble can get a bit dreary, the treble on my 685s can cause sibilance which makes long listening periods hard. I was thinking of some Acousic Energy Ageis Evo 3 as they allways come with great reviews and can be picked up for £200~ or the aelite 3s (which I can't see for sale anywhere) Anyone have any suggestions what I should look for?
