Spectral DMA-150 Stereo Amp Trades OK,

Here is a one owner Spectral DMA 150 solid state stereo amp that retailed for $7,500 - save big on this awesome amplifier. Fresh trade in from an East coast surgeon who purchased as new from his dealer and used very little - good shape and amazingly great sound. This amp is a top rated unit with great reviews and sounds amazing. Shipping will be $59.00 in the Cont USA via FedEx to your door.

I DO HAVE A PAIR OF MIT Mi330 INTERCONNECTS AVAILABLE FOR $299 EXTRA

ABOUT THE AMP

Like the innovative DMA-180 Reference Amplifier, the DMA-150 utilizes Spectral’s unique "Focused Power" output section design with powerful ultra-fast Mega FET devices. Each device, having vacuum tube like operating character, is energized from its own dedicated high energy storage capacitor, rectifier, and individually powered from an isolated ultra-low coupled transformer winding. Individual Teflon bias trimmers are used to calibrate each output device separately. Groups of these individual output device/power supply circuits utilize field folding construction and electronic shielding to further impede propagation of stray interference. The resulting "Focused Array" of individual isolated output sections performs as one with virtually no cross-coupling and energy storage artifacts reflecting between output devices. During extreme program dynamics, this arrangement can launch an instantaneous high current drive of over 60 amps per channel to the most sophisticated loudspeakers with assured precision waveform tracing. Gone are performance damaging magnetic and electrical field propagation problems of conventional multiple device heavy construction. Without stray radiation, critical small signal paths within the DMA-150 and other sound system components can perform with lowest distortion and settle to signal extinction in micro-seconds. Hence, the DMA-150 works with power and speed yet behaves inert to other electronic parts of the system. Reproduction is highly articulate and resolving yet has all the powerful unlimited character of the best very high power amplifier designs, giving little suggestion of its actual 150-watt-per-channel output specification.

The architecture starts with Spectral’s elaborate high performance custom power supply transformers. These unique designs are the result of years of research and development to maximize isolation and regulation. Each transformer features individually isolated windings to support each individual output transistor in the amplifier output section, a premium technique shared only with the Spectral DMA-180 Reference Amplifier. The twin power transformers are mounted between massive machined mounting plates for damping and resonance control. The combined 38 lb. Transformer structure is then mounted on a constrained rubber floating suspension system employing multiple compliances similar to a fine turntable suspension. The finished transformer assembly is then suspended inside an EMI, RFI tight welded aluminum containment box located directly beneath the DMA-150 output section
