I have a QSC PLX 1602, which is great. But seeing all of these cheap mini amps like the Shuttle and LMII, which put out 500-600 watts at 3 pounds or so, is making me wonder: are there any stereo power amps out there like this? I have a stereo rig, and I'd like to keep it stereo, but I'd love to have something that is just the power section from one of these mini amps, times two in a single rackmount case. I know there are things like this that cost several thousand dollars, but since the mini-amps are around $700, it seems like it wouldn't be too farfetched to take just the power section and sell it for less than the whole amp with pre and EQ sections. Is there anything like this? A cheap, lightweight, stereo poweramp with around 300-500 watts per channel into 4 ohms? Am I outta my mind with greed here?
