Who here has a QSC RMX850, RMX1450, RMX1850HD, or RMX2450 power amp? How do you like it? These are starting to float to the top of my pile of contenders because: 1) They seem to have a good rep for bass use (I've heard multiple complaints that Mackies lack a solid bottom); 2) They're cheap for the power ($400 for a RMX1450); 3) People seem to think they're rated conservatively; and 4) They're available from MF, where I have a line of credit! The downside seems to be weight and resale value, plus they're made in China (I have political / human rights / environmental objections there). I'd consider a PLX series amp, but they're a bit rich for my blood. I want to buy an amp on credit for a month or so, not a year of payments! The specs for the RMX1450 are where I think I need them to be for driving a pair of Bag End S15-Ds - 280W/8 Ohms stereo, 1400W/4 Ohms bridged.
