Power
The Cyrus Power was an exceptionally versatile power amplifier with outstanding performance in its many optional configurations. In a basic installation the Power is an extraordinary 50W/Ch stereo amplifier with an unrivalled level of performance. At a flick of a switch and an added PSX-R this unit transforms to a fully balanced 100W monobloc, with a far higher perceived power. The Power, of course, may be upgraded by adding a PSX-R in the stereo mode with its associated enhancement in performance.
The propriety current-feedback amplifier design constitutes the basis of the Cyrus Power. Our application of current feedback principles, rather than conventional voltage feedback methods, enables ultra-fast slewing of 700V/mS and negligibly low distortion at higher frequencies. The result is an exceptional sweetness and clarity in the midband with an attractive silky top end. Finally, an authoritative bass response with convincing scale and weight underpins the overall rendition of program material.
A unique power supply rejection system using low noise active isolation techniques prevents power supply modulation imprints from reaching the sensitive low level circuitry, virtually eliminating all traces of mains related harmonics on the amplifier output. In monobloc mode of operation the Cyrus Power fashions a massive 100W of extraordinary power through noise-free DC energy drawn from the accompanying PSX-R. The fully balanced configuration of the amplifier in this mode dispels all ground currents, enhancing the silky midband of the Power and adding further weight and scale to the bass. This, of course, is over and above the natural 3dB power thus gained.
