Model 501

The Model 501 is a 500-watt monaural amplifier enclosed in a chassis milled from a solid block of aircraft-grade aluminum. We believe that this approach to isolation contributes significantly to the amplifier’s ability to isolate delicate audio circuitry from external vibrations and electromagnetic fields. The Model 501 incorporates advanced digital output devices that, when driven precisely, provide an extremely accurate transfer of energy from amplifier input to output. Midrange sonics are rendered in smooth and linear fashion, while bass is tight and defined. Treble frequencies are extended and refined. Its incredible power reserves allow it to accurately reproduce the mightiest orchestral crescendos while maintaining the delicate filigree of quiet musical passages. The 501 enclosure never heats up much beyond body temperature and can be placed virtually anywhere within the listening environment. The remarkable size and weight of the 501 allows for placement rarely noted in previous high-power amplifiers. The 501 is designed to successfully drive the great majority of modern loudspeakers available today.
