RARE CONSECUTIVE SERIAL NUMBERS (SN# WU1527 & SN# WU1528)!
These MC501 dual monoblocks are in very good overall condition and were tested in October 2023 to ensure performance before selling (they passed with flying colors!). Previous G3Fi demo room product with B&W 802 D4s but upgraded the amplifiers to power the demo room's Focal Scala Utopia EVOIIIs, as seen in some of the MC501 pictures. There are a very few cosmetic blemishes as shown in the pictures. Everything else is either a reflection or dust. These monoblocks were purchased from the original owner and original boxes, manuals, and accessories are included.
Stereophile Magazine Review: McIntosh MC501 monoblock power amplifier | Stereophile.com
The MC501 Monoblock Power Amplifier has been designed to meet the expectations of
the most demanding audiophile. Delegating an individual amplifier to each speaker eliminates any chance of interaction between channels and expanding into multi-channel formats is as easy as adding additional amplifiers. Quad-Differential Circuitry, exclusive to McIntosh, reduces noise and distortion to their lowest possible level. While the MC501 delivers a massive 500 watts continuous power into 2, 4 or 8-Ohms and over 1200 watts of peak power into low impedances, its noise levels are 124dB below rated output. This means that the MC501 combines super-high power with record-low levels of noise…nearly an impossible combination!
The MC501 has a bold look yet is unmistakably a McIntosh. It features a 2-dimensional
glass front panel containing a large peak-responding true-wattmeter, all illuminated with
cool running, ultra long-life LED fiber-optic lighting. The chassis gleams in polished stainless steel and vertically mounted connectors at the back make attaching cables easier and takes up less shelf space. Both unbalanced and balanced inputs are provided along with three sets of huge, gold-plated speaker binding posts for high-performance
speaker cables.
