Thank you MRT, much appreciated. . . both Gilmore and your friend are likely real optimist on break in time. . . As posted elsewhere, I suggest that about 1,000 hrs are a must for ICEpower switching amps fore they truly sing. Jimmy, you will have a lot of fun with the excellent Nuforce monos. Try to find out how many hrs of playing time they already have. . . . if you can, connect a tuner to them or a CDp on repeat, and let them play no stop for those 2 weeks. . . and only toward the end do some critical listening. Many people have dismissed switching amps prematurely because of simple lack of patience. If you could keep them around for one entire month, it would be best. . . . considering that they are probably partially already broken in, by the end you should truly be able to tell what they are capable of doing.
