OK, I have an SWR Grand Prix preamp, but no power amp. So I need to buy a power amp pretty soon. I don't need a huge amount of power; I was always happy with the power of an SWR Bass 350 I just sold (but couldn't afford to keep both the Grand Prix and the 350!) I would like to limit the weight of the power amp as much as humanly possible, though. Any advice? The Carvin DCM-600 looks like a great deal at 19lbs. and $319.00, but I don't know anyone who has one I could hear or try.
