So I just picked up one of these, but I really wanted a pair of them. I work banker hours, so I have not had a chance to really test it out, but I did plug in a bass and played through a track. I have to say, it really sounds really good!
I do have one silly small complaint about the unit though. The power switch is on the back, which does not make sense to me at all... I do have a power supply to turn my entire rack off, but I am not always going to need to use my pre-amps and such. So most of the time I just leave them off unless I am using them. Won't be able to do that with this one, unless I put it in a separate rack or something.
