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
