Cambridge Audio Azur 550C CD Player, Black

The new 550C offers mind-bending performance from what at first appear to be a relatively modest design. Indeed simplicity and purity is the name of the game with the Cambridge Audio's latest CD players which deliver excellent dynamics, clarity and superb timing from music of all genres. Arguably the most important development is the introduction of an entirely new in-house designed servo solution. Whereas many 'comparable' CD players utilise an inferior CD/DVD-ROM derived drive, the 550C takes full advantage of Cambridge Audio's audio-only, CD transport which is coupled to our new highly sophisticated S3 Custom CD ServoTM. This third generation audiophile servo employs an all-new chipset and the latest double-sided surface-mount technology for ultra short signal paths with freedom from wire links. The net result gives the 550C extraordinary ability to retrieve maximum digital information whilst maintaining extremely low jitter; the digital noise that affects your listening pleasure. The 550C's well-proven transport has been re-worked to facilitate even quieter operation and a new bracing mechanism (derived from the 740 Series) guarantees incredible rigidity. As with all Azur CD players, a high quality toroidal transformer ensures lower noise and less waveform distortion as well as incredibly quiet operation. With so much shoehorned inside, it's astonishing how the new Azur 550C looks so elegant. In addition to a raft of sonic and environmental benefits, the new Azur range has a completely fresh contoured look with razor sharp displays and velvety smooth controls. A substantial brushed aluminium front panel, a seamless wrap-over lid assembly and dual-layer damped feet all adhere to Cambridge Audio's rock-solid design standards and also help improve performance through superb resonance control

Inner panel: the famous 24db filters.

Designed by Robert Moog in 1970, the Minimoog Model D synthesizer is still regarded as the Rolls Royce equivalent for analog keyboard-based synthesizers. Specifically designed for touring musicians, the minimoog exported electronic music experiments from university labs out to the masses - and her deep farting bass-sounds (think of Kraftwerk's Autobahn), lead and space bleeps and sweeps have become HUGELY popular over the last 38 years.

There were originally 13,000 minimoogs produced between 1970 and 1981. After a brief hiatus during the digital-synth craze in the 1980s, the minimoog enjoyed a resurgence of interest among musicians since the 1990s...and yes, it's becoming harder to get a hold on one.

I obtained this Mini from a studio garage sale back in 1989 for US$ 150 (in prime condition - save the crackling external input knob). After lying dormant for 7 years now, it's time to bring life back into this 1973 model D mini. Tropical humidity heavily damaged the furnishing. It needs re-tuning of the oscillators, cleaning of the electronic board, new switches for filter modulation, and thinking about a new base panel.
