PC for Brsyton 4B SST

Install two dedicated AC lines before you spend money on a power conditioner. Both my Bryston amps had inky black backgrounds with stock cords plugged into non-dedicated outlets. You might call Bryston and see what they suggest. Their customer service is impeccable, as I sure you know.

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

You say you can't hear the buzzing from your listening position. How close do you have to get to the speakers to hear the buzzing, and how high do you have to turn up the volume before you hear buzzing?

I hear buzzing from my speakers if I turn up the volume to 1 o'clock and I get within a foot of the tweeter, and this is with a dedicated line, and Hydra 4 conditioner and TG Audio 688 power cords. Most people, including the manufacturer of First Sound preamps told me this iis normal.

Sometimes the quest for complete and utter silence can get a little compulsive!

Tvad,

My listening distance is 10.5ft and I hear the buzzing from 1.5ft away. It doesn't seem to increase in intensity as I turn up the volume. I can't judge position with my volume nob but from 17dB-0db there was no increase in intensity. At +9 db maximum setting the buzzing did increase.

I've read that Nad recievers have dirty transformers hence the noise. What do you think I should do. I do have my reciever plugged into a Monster HTS2100.

Is it a loud buzz, or relatively quiet buzz? The buzz from my speakers is
pretty quiet...I almost have to put my ear to the tweeter to hear it.

I guess you have a digital volume control (or at least a digital reading on
your NAD), give me some perspective of the scale...what's the minimum
value and the maximum value? I can't get a feeling for -17db-0db and
+9db on a scale.

I'd try to borrow another receiver and/or amp + preamp combo, put it in
the system and see what happens. Do you have a dealer who will loan
you a demo unit?

Have you tried going straight to the wall? If so, is there a definite
increase in buzz?

Also, start with just your Bryston connected to the speakers without your
NAD or any source connected or plugged in. Does the buzz exist? If, so,
you can eliminate your receiver and source as the cause. Then, add
components one by one until the buzz returns. Then, you'll have traced
the cause of the buzz. Of course, if the buzz exists with just the Bryston
connected, you know the cause, and a call to Bryston is in order.

I don't personally believe you will solve the buzz with power cords, and
I've NEVER had a power conditioner eliminate or reduce the buzz from
my speakers. I've used Bybee Signature, Audio Stealth Magic Mini and
Digital Mini, Panamax something-or-other, Dezorel G2 and Hydra 4. My
feeling is speaker buzz is usually related to grounding issues either
helped or exacerbated by components.
