Regarding the Rowland 302's power supply, if my memory is correct, I can recall seeing a picture of its innards and there was a beefy torroid along with ICEPower 500A modules. However, it is a power supply with a difference: Rowland uses power factor correction. This is not mere marketing fluff, and as far as I know the only other manufacturer that uses this technology is Halcro. This module regulates the power so that the voltage and current waveforms are identical and in-phase, and it is apparantly one of the "secrets" behind Halcro's incredible performance. I haven't heard the 302, but I have heard the Acoustic Reality eAR amp so I know how outstanding the ICEPower technology can be when it is executed right. This coupled to the price-no-object nature of Rowland's all-out assault on the state of the art in amplifiers gives me little doubt that the 302 is a stunner. Then again, at its asking price, it better be.
