Hey Folks, Hopefully I'm getting a lighter rig thrown together soon ( I love my d-180 but oi is it heavy for 200 watts!) and I've been tossing around the idea of using a studio pre as my preamp rather than a usual demeter, aguilar, eden, etc. preamp. So, I suppose my question is this: has anyone used one for any length of time? If so, how do you like it? I really like the clean tone of the iAMP series, but i wanted a more modular setup.
