...a few words about Spectral Audio Associates...
Founded in 1977, Spectral is one of the most respected names in high end audio today. Spectral Audio makes wide bandwidth, extremely fast, high resolution amplifiers. Notably their amplifiers use many smaller distributed power supplies, rather than only one large one. This approach allows Spectral to locate a power supply (capacitors, rectifiers, regulators, and secondary windings) closer to each FET output device. Spectral amplifiers have a very transparent sound, with excellent settling (the ability of the amplifier to stop the speaker after a transient).
The DMC-10 Alpha with proprietary DMS-10 power supply:
Spectral took the basic design concepts of the MS-ONE and rationalized them for a decade of production. The result was the straight line, ultra-linear DMC-10, an instant classic.
The first product to feature Spectral's unique "systemboard" construction, an approach typically found only in instrumentation-quality design. Systemboard construction unifies the active portions of the preamplifier, including the connecting jacks, into one part which docks with the passive section, including the chassis and controls. The benefits for performance and servicing are considerable.
The first preamplifier to utilize power MOSFETs. In their freedom from the harsh distortions found in other solid state devices, power MOSFETs more closely approximate the performance characteristics of pentode vacuum tubes. Spectral's close ties to leading edge Silicon Valley companies have enabled us to consistently take the initiative in adapting state-of-the-art technology to audio use.
The DMA-100 Power Amplifier:
The DMA-100 class A amplifier was the first power amplifier to meet the standards of the Spectral performance envelope.
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.
