CYRUS 'POWER' power amplifier

Further Information: 

Its time for spring cleaning, so doing a bit of a cleanup on my 2nd system. I've got too much gear (is that really possible?) and not enough space, so having to move these pieces on.

I've been running a Cyrus 3 amp and this matching 'POWER' power amp for a few years now, and its been a superb combination. I bought this model as it was the match to the CYRUS 3 model I have.

I was bi amping, so I had the CYRUS 3 driving the upper frequencies on my speakers, and the POWER driving the bas drivers. Its a kickass combination, with rhythm and drive like few brands can do. Found the CYRUS amps to be perfect matches for PMC speakers, but they also sang on my Dali office speakers, delivering a sweet but authoritative sound, with amazing bass and rhythm. And don't be deceived by the modest power ratings - this amp rocks and has plenty of current supply to drive all but the most difficult speakers.

This POWER amplifier was sent off to Tim at Tuned In Audio with the CYRUS 3 and PSX-R units for him to check them over and do some of his magic updates to them. So this POWER amplifier is running perfectly, perhaps better than when it came out of the factory, and is good for another 15-20 years. OH, and Tim replaced the stoooopid speaker sockets - they have been replaced with proper banana plug sockets, so you don't need any obscure/funny adaptors

Its a pity I have to split the combination up, as they really work well all together, so if anyone ants to buy the CYRUS 3, CYRUS Power power amp, and 2 x PSX-R I'll do a special price and throw in a Logitech Harmony remote programmed for the CYRUS 3 and the FM6

I have an original CYRUS box so post Australia wide is no issue

And now the obligatory manufacturer info...

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.
