Spectral DMA-100S Power Amplifier RCA/XLR Audiophile High Quality - 220 VAC As the manufacturer describes this product - In 1982 Spectral engineers pioneered the industrys first wideband, high-speed audio power amplifier. The Spectral DMA-100 Class A Instrumentation Amplifier marked the origins of Spectrals unique fast-settling fet amplification topology and, in concert with the innovative DMC-10 Preamplifier, formed the first high-speed, high-resolution audio component system. Almost eighteen years later, Spectrals precision approach to component system design continues to evolve and receive wide acclaim as the ultimate in signal accuracy and realism. High-speed amplifier technology was first made practical by the DMA-100 Class A amplifier and all subsequent Spectral amplifiers draw their basic engineering inspiration from this original benchmark design. To commemorate the introduction of the first high-speed instrumentation audio amplifier, Keith Johnson and the Spectral design team are pleased to introduce the new DMA-100S Compact Reference Amplifier. The DMA-100S pays homage to the original Spectral amplifier while setting contemporary standards in musical performance and high value for the millennium. Inspection of the new DMA-100S reveals many similarities with the original Spectral amplifier, including similar power and topologies. Although alike in many regards, the compact, cool-running design of the DMA-100S attests to the many engineering advances made since the 1980s at Spectral. The DMA-100S is actually a contemporary marriage of our state-of-the-art DMA-150 and compact reference DMA-90 technologies. Conceived by Dr. Keith Johnson as a compact reference for recording work, the DMA-100S features a magnificent combination of design elegance and convenient size mirroring the classic packaging of our SDR-2000 and SDR-3000 reference components. As with earlier Spectral compact amplifiers, little in the restrained appearance of DMA-100S forewarns of the unusual performance potentials which exist within. For under the hood of the compact DMA-100S lurks the heart of the DMA-150 Reference Amplifier with its proprietary Focused Array output section design. In this premium topology, each matched output device is mated to its own power supply, including individual filter capacitors, rectifiers and transformer secondary windings. This breakthrough topology aligns high-current fet output devices for rapid, pistonic signal launch, with full rated power delivered with absolute load stability at 1 MHz. The resultant output section response capability is unprecedented in an audio amplifier of this power. Speaker control with the DMA-100S is startling, with transient and dynamic resolution of fine recordings equalled only in our most premium amplifier designs. The high-value DMA-100S makes premium discrete circuit topologies, which were only available previously in Spectrals high-current reference designs, available for a fraction of the cost. The DMA-100S offers state-of-the-art performance, new design refinement and extraordinary value in the Spectral tradition. The DMA-100S represents the innovative thinking and quality commitment of the original Spectral DMA-100 and more. We think you will agree, some good ideas really deserve an encore.

For sale Spectral DMA-150 S II Power Amplifier RCA/XLR Audiophile High Quality - 220 VAC As the manufacturer describes this product -The DMA-150 High Resolution Amplifier shares with other Spectral components the creative uncompromising use of edge-of-the-art technology, dedicated precision manufacture, and Spectrals experience with live sound at recording sessions. From extensive listening and design experimentation, Spectral has consistently pioneered component systems having fast settling, high-speed circuit architecture. These have invariably outperformed more traditional often cumbersome high-end design methods to achieve superlative detail, staging and listener involvement. Indeed, test methodology simulating music waveforms and hearing acuity confirm that quickness of response and rapid signal extinction when reproducing complex dynamics are mandatory for accurate music reproduction. Only then can one preserve instantaneous waveform accuracy to prevent cover-up of delicate musical signals by previous events. Construction and performance of the Spectral DMA-150 High Resolution Amplifier for this demanding criterion and resulting sonic resolution are unmatched among contemporary high-end amplifier designs.. Like the innovative DMA-180 Reference Amplifier, the DMA-150 utilizes Spectrals 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.Cosmetic Condition: The Amplifier has minor signs of wear and tear as it has been in use, however these signs of wear do not affect its performance or performance.

For your consideration is a rare pair of audiophile interconnects. These are for use with Spectral audio products which require (or so they say) a very specific type of cable for optimal performance. They are manufactured by MIT and are branded SPECTRAL MI-500 COMPONENT INTERFACE CABLE. This pair was used to connect a Spectral preamp to a Spectral power amplifier. Works great, nice condition. Each cable is 60” in length from tip to tip. Feel free to ask any questions. International shipping available via eBay Global Shipping. Be sure to check my other listings for more MIT / Spectral cable. Thanks for looking!

For your consideration is a legendary Spectral DMC-12 preamplifier. This classic audiophile preamp comes complete with the original power supply, power cable, Spectral (by MIT) RCA cable and a built-in phono section. No original manual or box included. Overall, this set is in fantastic condition! Very, very clean and functioning as it should. There is one very small rub mark on the upper left side of the faceplate which is hardly noticeable. I have tried to show it in a close-up photo but it’s still hard to see. Other than that this piece looks almost new. Very clean inside too! Please examine all of the photos for a good visual description. Feel free to ask any questions. Thanks for looking!

Spectral are one of the few audio companies that from day one have always made truly high end products and no mater what their age they represent a solid investment for anyone who is serious about their music. I am the son of the original and proud owner. The amp is fifteen plus years old, it shows, at fifteen plus years nothing is going to look new unless it has been put in a glass case only to be looked at, works perfect though. This is a full Dual Mono amplifier. It has a XLR (balanced) input as well as single-ended (RCA) phono jacks. Comes with a detachable IEC power cord, can accept 240V, 220v, 120v and 100 volts. A true workhorse. Below is some information from Spectrals web site. The DMA-100 was the first, direct coupled, high speed, DC-to-megahertz amplifier for audio and the first high speed medium band (up to low radio frequency) amplifier for laboratory use. The first full FET technology power amplifier, utilizing J-FETs as well as power MOSFETs. The DMA-100 was a true 100 watt amplifier, capable of delivering 100 watts per channel into any load. The first solid state amplifier with no capacitors in the signal path. Sorry no pictures right now but possibly in the next few days. Paypal no problem, add four percent.
