CLASSÉ CDT-1 compact disk transport High End quality digital transport Good Look

Description

The Classé CDT-1 compact disk transport is high quality digital transport utilizing the latest innovations in digital audio reproduction. The philosophy behind the CDT-1 is advanced technology for extracting the maximum musical performance, but also embraces the time proven idea of simplicity, in accordance with the saying "simpler is better."

No effort has been spared in the development of the CDT-1. The chassis is of exceptionally thick gauge metal, and has been designed to resist vibration through solid construction and proper isolation from sources of vibration. The half-inch thick faceplate is a tribute to its construction and aesthetics. Inside, main power is provided by a custom high-current 27VA toroidal transformer. The power supply of the CDT-1 is generously oversized to assure that regardless how much current is drawn, the circuitry will remain unaffected by any fluctuations. Numerous power supplies are used, to assure the elimination of interference caused by fluctuations often induced by heavy current draw on shared supplies.

The CDT-1 inherently has a low power consumption, but micro-information is easily contaminated when traditional power supplies clip due to their inadequate output. This is the general idea behind the high current, stable supply that powers the CDT-1.

The disk transport itself is the latest Philips CDM12.4 with the L1210 Loader assembly. This mechanism employs a newly-developed linear tracking laser pickup which is faster, quieter, and longer lasting that the well received CDM9 Pro mechanism. The isolated suspension system of the CDM12.4's optical circuitry and disk motor is completely separate from the disk tray, eliminating micro-vibrations caused by sudden atmospheric pressure changes around the front panel. The CDM12.4 is of broadcast quality, and its outstanding construction using highly efficient, long life motors assures excellent longterm reliability. In addition, this transport is designed not to require periodic calibration, assuring that long-term alignment will always be right on specification.

Jitter, also known as errors in the time domain, is the prime factor in performance degradation, and Classé has addressed this problem from every perspective. One aspect is the outstanding power supply described above; another is the exceptional reclocking circuitry. Using a 16.9344 MHz crystal oscillator to generate the digital outputs, the final jitter measured at the outputs is typically so low it can barely be detected. The crystal oscillator itself is designed to generate a spectacularly low jitter of 14 approximately 2 picoseconds! Standard outputs are an AES/EBU balanced on an XLR 3-pin Neutrik connector, a Hewlett-Packard optical ST output and an S/PDIF coaxial connector using a heavy-duty gold-plated RCA jack.

A final technical highlight of the CDT-1 is the custom remote handset. It features an exceptionally wide transmission angle to the IR receiver on the CDT-1, and is engineered to last an extremely long time.
