I'm downsizing and reluctantly need to sell my Spectral system. I purchased these DMA-400 RS mono amps new from an authorized dealer and have only used them in an all Spectral system with the requisite Spectral interconnects/speaker interfaces. They are in pristine shape and have been used in a smoke and pet-free house. I hate to see them go, so my loss is your gain.
I will include the original manuals, purchase receipt, and they will be packed in their original boxes and crates.
