For sale is a DMA-100S Spectral amplifier. It is in excellent condition with original box and owners manual. It has always been used in an all Spectral/MIT system. I'm selling only to move up in the Spectral line. Gorgeous sound. This unit replaced a DMA-150 S1 and sounded better, but had less power. If my asking price is met, I will pay the Paypal fees. For all other offers, Paypal users please add 3%. I can also accept a money order or personal check. US 48 states only please. Thanks for looking.
