I'm currently using an swr studio 220 as a preamp with a dbx 166a compressor on the effects loop, into a crest CA-4 power amp. It is "my sound", but my rack weighs significantly more than the eden 4x10XLT it powers. The thought of 3000 watts at 6lbs for $300 sound pretty appealing to my aging back and sagging wallet. Does anyone have any experience using the beheringer iNuke series of power amp for discreet bass guitar power? How does it sound? They seem to review very well for driving PA/subs. They at too new for reliability reviews, but it seems the class D amplification world is improving every day by leaps and bounds. I understand my crest CA is gonna be hard to beat, but 50lbs just for the amp is getting old.
