Hi everyone!! Im expecting to buy a new amp, and Im going for tubes, but the problem is that I have to many choices and cant decide for one. I have these options:

-Peavey Triple XXX (when i tested it, a lot of f*** noise at 3 in master Volume)
-Marshall TSL-60
-Marshall DSL-100
-B-52 AT 100 (Noise either)
-B-52 ST 100 (also nosie!!!!)

What is the reason of the noise on that amps??!!! Do i have to active The ground lift?? or what???!!!!!

I played Progressive Metal the most (Dream Theater), but also some Metallica Stuff. The guitars?? I have a Petrucci OLP model, and a B.C rich warlock Platinum series...

Do you have another good option?? Tell me please!!!

I wait for your repplies and i really want to thank all the people on this forums that help people who are completely lost in this maze!!!
