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

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.
