Buzz from speakers

Terry, why would swaping speakers eliminate the buzz?? The buzz/hiss actually came out on both speakers and this happen even the ONLY amp is on. I tried some other speaker cables, still doesn't help. I brought the speakers and amps to another outlet, still doesn't help either. I then tried to put the audio note mono block (2nd system), the buzz still there.... :(

Linkoping,

I know how frustrating this can be. I just had this problem when I changed preamps from an ARC to the TAD-150 by Bizzy Bee. I put a cheater on the preamp power cord and it went away. What kind of surge protection are you using. If monster, there were problems with some of the TAD-150;s . As soon as the surge protector was changed the problem went away. There are different kinds of isolation devices that you can get on audiogon. Tripp lite makes some good ones. If it is a 60HZ hum that is usually a ground loop problem. If higher pitch buzz maybe some component in your electronics is wearing out. If you have a turntable make sure that the ground is connected securely to the ground terminal on the pre. good luck!!!! Let us know how you solved the problem. May help some other people on this site.....

Thought you had buzz in one speaker only. Ground loop is often louder in one speaker, not always though.

You had CJ amps before the Art Audio. Did you have a buzz with the CJ? If not, could be the transformers on the Art Audio or one of the tubes (possibly going bad). Low powered SET amps are often guilty of displaying audible hum or buzz. Won't mention brands in deference to the manufacturers, but it is not that uncommon.

Do you have another amp you can substitute?

When you play music, can you still hear this "buzz" through the music?

Make sure you use the most pristine recording possible for your test.

Don't mistake "take hiss" from the original recording for the hiss you're hearing with only the amp connected.

You may just be hearing "hiss" from your speakers due to bringing raw current to them from your amplifier.

This is common and not necessarily a problem. In fact, the more sensitive your speakers, the louder that "hiss" with no music playing.

You can "clean" that hiss with dedicated circuits and AC Conditioning, but it is unlikely you will eliminate it.

If that hiss disappears when you play music with no hiss in it, it isn't a problem.

Also, listen from your listening position, not with your ears so close to the speakers. If you can't hear the hiss from your listening position with only your amplifier connected, I wouldn't worry about the hiss, but I would still consider dedicated circuits and/or AC Conditioning.

Several of the above problems will cause a buzz; cable TV connector, a bad tube on the amp or preamp (I'm not familiar w/ your models) or some other device on the same circuit that is emmiting "something" (EMI/RFI). You say the listening room is in a garage. What other components/appliances do you have on the same circuit? Is the electrical wiring in the garage the same as the rest of your house (i.e.,not installed later)?

Also, is this a "new" problem? Did you not have this problem before with previous equipment in the same room? If not, did you introduce anything new into the system?

I know I'm asking a lot of questions but as I'm sure you know, it is a process of elimination.
