PC for Brsyton 4B SST

OK, no buzz, but hiss with only the Bryston connected is normal. Did the hiss go away when the amp is connected to the Monster? If not, it would seem the Monster doesn't provide much conditioning, but perhaps some surge protection, which might be important to you. Otherwise, what's the point of the Monster other than a glorified outlet strip?

The buzz comes in when you add the receiver. Connect the receiver but leave it unplugged. Any buzz? How about when you plug the receiver in, but don't turn it on? Now, turn it on. Do you see the methodology here? I'm assuming during this you have no source connected or plugged in. If you do, then you can't isolate the problem to the receiver. Take it one step and one component at a time.

Are you connecting the receiver via balanced cables? If so, try single ended cables or vice versa.

I was doing this exercise once. I had no buzz with just the amp. I got a buzz with the preamp connected and plugged in, but without a source connected. Once I connected the source and plugged it in, the buzz went away! Who know why? I don't.

If the buzz occurs when the receiver is connected with a source, I'd try borrowing a preamp and see if the buzz goes away.

The hiss was still present with the amp connected to the powerbar. The buzz is Present when the amp is turned on. Connections are via RCA.

Here is what I've come up with so far.
Reciever on ,amp on but no RCA cables=no buzz
Reciever on,amp on connected=buzz
Reciever connected to amp but unplugged=buzz
Reciever on,amp off=no buzz
Reciever off,amp on= buzz
Both on=buzz
Source components connected/disconnected=buzz

At this point I thought it might be my rca cables but when I connected my speakers to my reciever like I used to have it the buzz was still there.

This is getting so confusing it's driving me to drink,smoke, and the night is still young.

I'd have to say it's your receiver. Borrow a preamp (or buy a good used one you can re-sell) and see if the buzz goes away. You can do a thread search for excellent inexpensive preamps. This question has been asked many times.

Also, you can decide whether the Monster is worth having. There are a number of good power strips available. Surge protection is another matter...OneAC, Powervar, Brickwall...all make good surge protector/conditioners that are high quality but inexpensive. Or, you can keep the Monster. :)

Tvad,

thanks for all the help. If I ever get this solved I will post it. I kinda thought it might have been my reciever. I don't recall the buzzing being present with my old reciever an Onkyo.

I'll try to see if I can borrow a preamp and do some experimenting.

Thanks

One other option. Your receiver or amp may be an ungrounded design. I'd guess it might be the receiver since I doubt Bryston would design an ungrounded amplifier. For example, I understand from John Tucker of Exemplar Audio that the Denon 2900 is an ungrounded design. Who'da thunk it?

You can try an AC cheater plug on the Bryston or the receiver to lift the ground. Try it on one then the other. It may do the trick.
