PDT 3100 HV CD/SACD Transport

The Reference CD/SACD Transport

The PDT 3100 HV is a purist CD / SACD mechanism wich does not feature supplementary integral digital sources or converters. It has been developed uniquely and exclusively for the uncompromising task of reading SACD and CD, and is fitted with a new decoder / drive mechanism which we have developed from the ground up. This mechanism reads and decodes CD and SACD without error and to the very highest standards of quality. The mechanism is integrated into a heavy drive unit manufactured to rigidly high standards, designed to shield and isolate it completely. The mechanical system is extremely refined.

Optimized Speed Mechanism

The core of the PDT 3100 HV is the new, modern decoder / disc mechanism, which we have developed specifically for audio applications. It features the latest processors, lasers, high-performance motors and other components, all designed to provide the optimum conditions for perfect, error-free disc reading characteristics. This unit is fully shielded, and housed in a very substantial aluminium case machined from solid aluminium, designed to prevent any form of interaction between the moving parts of the mechanism and the remainder of the player. This entire disc mechanism block is mounted on just two close-tolerance linear bearings, which in turn are suspended from a thick carrier plate; the latter is fixed to the central case plate at only three points. This design ensures that the whole mechanism is completely isolated from the heavy external housing.In the HV series the signal switching and adjusting functions are carried out by encapsulated gas-tight gold-contact relays, which are totally immune to contact problems due to corrosion, dust, etc., and do not suffer from ageing effects even after many years of operation. The pre-amplifier even employs bi-stable relays, which require no permanent coil current, and this in turn eliminates any adverse inductive effect on the audio signals.
The direct integration of the relays into the circuit minimises the signal paths, and connecting cables – as required for conventional volume potentiometers – are no longer necessary. The volume control is assembled from discrete precision resistors and gold-contact relays. The result is totally precise channel matching, devoid of distortion and hiss.
