Spectral DMC-15ss:

The new DMC-15SS Studio Standard Preamplifier reflects Spectral’s core engineering commitment to design the industry’s most sophisticated preamplifiers in the most purposeful, affordable and uncompromising manner possible. With thirty-five years of intensive design evolution, Spectral high-speed reference preamplifiers have achieved an unrivaled record for combining edge-of-the-art musical performance with high value. The recently introduced DMC-30SS Studio Standard preamplifier has raised the bar substantially in a highly competitive market and is widely considered to establish a new sonic benchmark with its superior control, power supply and high-speed output line sections.

Now Spectral engineers have applied the new design refinements developed for the DMC-30SS to the ‘straight-line’ DMC-15. The resulting DMC-15SS Studio Standard preamplifier redefines the value/ performance equation with breakthrough power supply topology and edge-of-the-art signal control. Unpretentious but elegant, the DMC-15SS dares the comparison with the world’s most elaborate and expensive high-end preamps at a fraction of the cost. The secret to this ability lies within. Under the top cover, the DMC-15SS reflects its true heritage as the manual twin of the extraordinary DMC-30SS Studio Standard achieving unmatched signal transparency, control precision and musical realism.

Spectral DMA-260:

The DMA-260 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-260 High Resolution Amplifier for this demanding criterion and resulting sonic resolution are unmatched among contemporary high-end amplifier designs..
