L'avis de Noir & Blanc
Spectral Audio is pleased to introduce the new DMA-300 Reference Standard amplifier, the second signature component in our Reference Standard line, Our first RS component, the DMA-400RS monaural amplifier marked the culmination of a multi-year research effort by our engineering team. Engineering director, Keith Johnson set as his goal for the new generation amplifier the elimination of subtle but intrusive energy storage artifacts occuring in active circuit devices. The solution, the creation of critical small scale driver and larger scale gain devices which exhibit virtually no energy storage or thermal tail memory represents a major advance in amplifier accuracy, and is fully implimented in the DMA-400 RS. Today, the DMA400 RS is recognized worldwide as an important breakthrough in high-end amplifier technology and a new reference for the most demanding system applications and the finest loudspeakers.
