M500
Mono High Current MOSFET
Control Room Amplifier
As an alternative to its stereo sibling, the M500 monoblock has been designed to offer the ultimate in smooth extended bandwidth for the most advanced audiophile monitoring possible. Utilizing the same twelve 100 watt MOSFET output devices and high current power supply, a different approach to the front end design has yielded a slightly warmer, less aggressive presentation with an enhanced and truly astounding deep bass response. Also, in our attempt to emulate the "tube" sound, a significantly higher output impedance has been used to provide a damping factor that does not vary with frequency. In traditional designs the lower damping factor exhibited at the frequency extremes is remedied in a tube amplifier's circuit by the necessity of using an output transformer... with its unfortunate contribution of sonic impurities. In the M500 we have applied the benefits of this concept without the drawbacks, providing very strict cone motion control at all frequencies. Since the M500 is not a bridged version of the S400, but a dedicated parallel mono unit, it does not supply quite the output of an S400 bridged, but is, however, quite happy at all impedances down to one Ohm. In stereo pairs the M500 will bring out the best from the finest monitors, while single units are the perfect choice when mono subwoofers are added in the nearfield environment.
