The new line of BC combos has, indeed, had a total makeover. Extensive R&D was done in a joint effort between Celestion and Jonas Hellborg, and utilizes many features of the high-end Hellborg Amp line in its design. Its a very well thought-out design with special attention given to circuit and component layout, which results in a very musical sound with low noise and no hiss/hum. With its symmetrical circuit layout - meant to reduce resistance, create as low impedance as possible, and provide proper grounding, it creates less thermal noise and needs less filtering of high frequency feedback - which equals a more responsive and musical sounding amp. The box/cabinet size is matched to its specific driver, and great consideration was given to every detail - including box/cab material and covering material. They really sound incredible!

is there a reason you guys went with Class A topology? it's rather old, and crossover distortion is pretty much a non-issue with modern AB designs. Class A also burns twice the energy that it puts out to the speaker, even when idle.
there's comments on the Youtube demos and Warwick forums that they are really quiet. what are the speakers in these? the BC-40's driver is rated at 89 dB SPL in its manual, which is pretty low. Andy Irvine and the reviewer in Leakim's link both had the amps past half way up.
