Spectral Audio DMA-200S

The DMA-200S High Resolution Amplifier shares with other Spectral components, the creative uncompromising use of edge-of-the-art technology, dedicated precision manufacture and Spectral’s 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-200S High Resolution Amplifier for this demanding criterion and resulting sonic resolution are unmatched among contemporary high-end amplifier designs.

Avalon Acoustics Compas for sale

We are selling our brand new in the box Avalon Acoustics Compas loudspeaker.

Inspired by the rhythmic time signature patterns of flamenco music, our COMPÁS illuminates the fundamental structural elements of metre and impulse in all musical genres. Primarily characterized by its dynamic and percussive rhythms, the COMPÁS delivers a disciplined performance with high transient speed and clarity of image definition. This constant Q design generates critically damped driver resonances from octave to octave throughout the audio spectrum. With a Q of 0.5 ringing and transient smearing is eliminated.

Control networks within the crossover designed specifically to target resolution and ambience retrieval under high current conditions are the heart of COMPÁS. Its unique ceramic/honeycomb woofers deliver an authoritative low frequency response with unsurpassed transient accuracy, carefully blending with the highs for a “true to source” sound reproduction. Proprietary low jitter circuitry clarifies image boundaries to a high-resolution standard suitable for professional monitoring where microphone placement and phasing are critical. Utilization of the same diaphragm materials throughout the array adds to the continuity of harmonic structure in a crisp, seamless musical presentation devoid of stored energy; its rock solid imaging presented with a palpable density through accurate and colorful harmonic structures.

All AVALON ACOUSTICs loudspeakers are engineered and built to the highest standards in the audio industry. Handcrafted in Boulder, Colorado by dedicated craftsmen and technicians, each COMPÁS is measured and matched creating perfect symmetry and coherency. Before leaving the factory each of our masterpieces is subjected to a demanding array of quality control and testing procedures to assure flawless and consistent performance. Our creations are a work of art in which we take great pride, designing and building each one exclusively here in the foothills of the Rocky Mountains.
