I'm sorry I've should have mentioned that I live in an apartment and dedicated lines is not an option. That is why I thought of a Power Conditioner. Even though I can't here it(Buzzing,hissing) from my listening position I know it's there and it bothers me. I just cant't figure it out.
If I must I'll live with it untill I move and get a dedicated room and power.
Tommorow I'll try to call Bryston and see what they suggest.
Many Thanks
