Spectral engineers pioneered the invention of high-speed fet audio amplifiers in the early 1980s with the wideband DMA-100 Class A instrumentation amplifier. From these innovative beginnings, Spectral has evolved increasingly powerful and sophisticated megahertz amplification for applications in the Spectral component system. Today these high-resolution amplifiers feature greater speed and settling capability combined with higher voltage and current than previously possible. The DMA-360 Monaural Reference is now the ultimate realization of this quest to achieve uncompromising amplification true to the live musical experience.
From much listening and design experimentation, Spectral has consistently pursued component systems having ultra-fast settling, high-speed circuit architecture. These have invariably out-performed 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-360 Monaural Reference Amplifier for this demanding criterion and resulting sonic resolution are unmatched among contemporary high-end amplifier designs.
