Spectral DMA-100S Series 2 Stereo Power Amplifier

On offer is my Spectral DMA-100S Series 2 power amplifier. I have owned it for six years and it has operated flawlessly. If you've read this far, I suspect you know what a gem this is.

This remarkable amplifier was designed by the great Keith O. Johnson, noted for (among other things) founding Reference Recordings. Prof. Johnson writes in the manual:

Improvements in high-current FET technology, high-speed amplifier topologies and new protection systems are combined in the DMA-100S dual monaural amplifier to successfully advance the the art of amplifier design. Until now, amplifiers could not offer both powerful speaker control capability and the sonic transparency and life possible only with high-speed, fast-setting circuitry. Breakthrough circuits backed by Spectral experience have now brought together the necessary combination of speed, accuracy, control and stealth. The DMA-100S High Resolution Amplifier advances the Spectral tradition for musical resolution and sonic holography. Although of moderate sIze, the DMA-100S offers remarkable sonic sophistication and drive precision for the most demanding system applications.

The power is specified at 100 W per channel into 8 ohms, capable of a remarkable 22 A output current per channel. More details can be found on the Spectral website: http://www.spectralaudio.com/dma-100S.html

I have conservatively rated the condition as a 7, although I wasn't aware of any cosmetic flaws until I started taking close-up pictures--see the photos. Spectral specifies performance with Spectral/MIT cables, and my cables are listed for sale as well.
