Suzy, is this the Suzy that I met over at AA? If so, HEY! Welcome to our world across town! I found that it's hard to get people to think about power cords until they are really eyeball deep into this madness and have upgraded everything else. When we started the upgrade journey, we started with the amps, then the preamp, and mingled everything else around those (eventually swapping out the whole setup, including all IC and cables -speaker and power)- even the amp another round or two until we settled where we are at the moment (have been for 8 months now!)The biggest difference that we saw was with the preamp. That is just our experience. It really does vary based upon what you have. (and the Line 3, with the right tubes, is mellow in the mids, detailed in the highs, and "ballsy" in the bass)
