Spectral DMA-360 Solid State Monoblock Pair

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

Monaural amplifiers from the legendary american maker Spectral.  

These puppies are rated at 300W each at 8 ohms, and 533W at 4 ohms.  

Internal and external construction and component quality is the highest I've ever seen.  I would rate these 10/10 functionally and 8/10 cosmetically.

This auction is for the 2 pieces complete with their manuals, boxes, and power cords.  New double boxes were just purchased from Spectral and were quite expensive. 

Cosmetically the exterior is in very good shape with no significant scratches or dents as visible in the pictures.  

One of the units has some discoloration on the plastic insert front panel only visible when the unit is powered off, just above the logo and barely visible on the pictures.  

The tops do not have any scratches and the aluminum faceplates are clean except for one small nick visible in the pictures.  The heatsinks are free of scratches or dents.  

Matching MIT interconnects, power cables, and speaker cables are also available - but not included in this auction.  Please contact us directly to learn more.
