I have a 737 that I am very happy with. Right now, a preamp is not my greatest need, as a pair of 1x12s would serve me much greater than another pre would. However, I've found myself drooling over the DB680 VERY much over the past few weeks. Am I ridiculous for wanting a 680 when I have the 737? Would picking up the Aggie be a bit of a redundancy at this point?
