I'm currently researching a power/pre-amp setup in my quest for more power. My minimum requirements are at least 250+watts per channel/stereo mode @ 8ohms, and a bridged mode that supports a 4ohm load. I've set my limit at $500. Lastly, I want new!! So far, I've come up with 2 units that meet my criteria. 1. QSC RMX1450 $399. 2. Crown UltraTech UT1010 $449. For the power/pre experts here, are there any other units available that meet my criteria?
