Thanks Ceejay, I did as you suggested and I do still hear the hiss, albeit only when sticking my head within 1 foot of the tweeter. Interstingly I took my SB3 back to the dealer and we plugged it in (same psu etc) and it was quieter. Now we weren't using my B&W 601s so I'm not sure if the 601's tweeter is much more efficient than the one to whiich we were listening. Additionally he suggested I may have an earthing problem, which I'm going to check this weekend. Is it likely that earthing the SB3 will solve this. Should this even be attempted? I'll do some continuity checks and measure the ohms between all the earth points on my components first I guess, then start fiddling.
