Buzz from speakers


Hi,
After all the long search, buy, sell, I pretty much done with my system. BAT VK-D5 -> Emotive Audio Sira LE -> Art Audio Jota (w/ KR300BLX) -> SAP J2001-MKII speaker (diamond tweeter, horn midrange and 12" woofer at 97db). The sound are great so far, missing the bass a little, but ok for my kind of music (classical).
However, I noticed there's buzz in my speakers. The buzz sound appear when I just turn the power amp on. I tried to switch the outlet, there's still buzz. I tried to lift the power cable, using cheating plug... tweak around, moving around, still can't get rid of the buzz...
In this case, would it be the amp or the speakers?
Any suggestion/idea will be greatly appreciate.

Thanks

My guess also is it may be your cable tv connection.I had the same problem and unplugged the cable tv connection and the buzz went away.Another possible problem you could have is i/cs and sp.cables touch or crossing over each other creating a buzz. I had that one too. I re-routed my cables and solved that too....Good luck
Thanks for all the responds. Actually, I don't have any cable jack in my listening room (the garage). No phone either. And when only the amp is on, if sitting 1 feet from speakers, you can slightly hear the hiss/buzz, especailly from the woofer.
When I turn on the preamp, and go for max volume, then the hiss and buzz become pretty loud that you can hear them from 3-4 feets away.

You can also swap speakers if you have another pair. The J-2001 are VERY revealing, so that may not work. But you could put the left speaker on right side and vice versa to see if the noise travels with the speaker.
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.....
