    alright, heres my setup

    sherwood r-956 receiver, sony cdp345 5 disc, samsung dvd
    psb image 6t's on kimber 8vs biwire and a pbj rca for the cd player

    when up close to the speakers i notice a little bit of static in the backround, nothing noticable usually, just on some quiet parts of songs and movies, would this be due to some interference in the power supply? my 32" sony is plug into the same power supply as the receiver, but the backround noise still persists when the tv is unplugged. anyone know of a cheap way of eliminating the backround noise? not looking to spend much money on it since its not a very noticable problem, and i would rather spend the extra money on a sub or center channel.

    i saw a belkin power supply that supposedly conditions the line for 60 bucks at staples, think it would work?

    Hard to say without determining if the noise is coming in on the power line, or inherent in your electronics. If it's your receiver that's generating the noise, cleaning up the power won't make much of a difference.

    Just curious,

    Are you running your video (S-Video/RCA) etc through your receiver, then to the TV?

    Reason I ask is that my Outlaw 1050 always did what you're saying when I ran video through it. It mostly was caused by the S-Video inputs however. To test it, I unplugged the S-Video from the receiver and ran it to the TV directly, then the hum was gone.

    Just a thought.

    alf, tried out the svideo idea, ran the receiver without the svideo in and it made no difference, the setup is in an old room with an old electrical system, so i'm thinking it's probably something to do with the power, i'll try one of those belkin power supplies and see if they make a difference

    I may be way out in left field but,if I remember correctly doesn't this slight hiss have to do with the amp?

    What I mean is I remember seeing a post on headroom of an amp where a better quality amp will have more head room & less hiss where as a lesser quality amp will have less headroom & more hiss,(no pun intended Matt so please don't take this wrong)

    I can say from my own equipment that my past two recevers had a noticeable hiss to them when you got close to a speaker with the vol about 1/4 up,& with my current system which is much better quality than my previous I have no hiss at all until the vol is up to around the half way point & even than it is almost unnoticeable.

    joe, you may be right, because i have to turn the vol up to about 1/2 up before you can really notice it when your next to the speaker, barely noticable at all when your sitting around listening to music, and it would make a lot of sense that a more expensive amp wouldn't have this problem.
