Does tubed gear make your speakers hum/buzz?

I've just started using my first piece of tubed gear. It's a Dared SL-2000A pre-amp. I've had it running in the system for about a week now. I really like the improvements this has made to my system.
My only is problem is that I just noticed that my speakers make this humming/buzzing noise when the pre-amp is on but no music is on. It's only noticable when you put you ear right next to the speaker but I still don't want it there. I'm not using any power condition on my system and I'm in a highrise apt building in NYC. Could this be the cause or does it have something to do with the tubes? I'm currently using it with the tubes that it came with.

By the way, I already tried the 3 to 2 prong,,,,,,didn't work.

help.

Meech, Put your money away! It is common to hear some tube rush sound or a tranny buzz in some designs. One thing to consider is floating the ground on the preamp and then try floating the ground on the amp itself. You may have a common ground loop. Go to your hardware store or Home Deposit and buy a ground floater plug and try it on the preamp and then the amp. Another source for buzzes is from your VCR. The source is actually from the coax from the cable company. They make filters for that as well.

The worst case is that the Dared has a poor grounding schema and you are stuck with the buzz, hiss or tube rush.

Good luck
