Despite advances in high-resolution file replay, the optical disc remains the reference standard for digital music replay. Those who have predicted the imminent demise of CD and who already danced on the grave of SACD might want to take a look at the rude health of the vinyl LP, a format long ago consigned by many to the dustbin of audio history. There have never been so many CD and SACD titles available – and they have never been so affordable, making them the most consistent and stable digital source currently available. They are a source that’s going to be with us for years to come, making a high-performance optical disc player central to any high-end audio system.

Product Description

The CH Precision D1 is a configurable CD/SACD player/transport, the card-cage output architecture allowing owners to optimize the output topology to suit their system requirements, whether they need a player, transport, or prefer to have both in a single unit. Built around a mechanically optimized implementation of the acclaimed Esoteric VMK-5 transport mechanism with its energy-sink construction, coupling the transport directly to a steel base plate, itself mechanically grounded via hardened steel corner posts, ensures minimum mechanical interference with the optical replay process, while basic output options include a digital output board (S/PDIF, AES/EBU, CH-Link HD and TosLink) or stereo analog output board (with one pair of RCA and one pair of XLR sockets). The CH-Link HD connection allows the digital output of high-definition material, including DSD, direct to the C1 or I1 DACs, while owners can also specify up to three of each board type, to accommodate multi-channel SACD replay. In addition, it is possible to fit a single pair of dedicated mono analog output boards to create a reference stereo player.
