CH Precision D1.5 SACD – CD – MQA Transport / Player

CH Precision D1.5 Reference CD / SACD / MQA Player / Transport

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. In fact, there have never been so many CD and SACD titles (or formats) available – and they have never been so affordable, making them the most consistent and stable digital source currently available – and one that is constantly evolving as superior materials and manufacturing techniques continue to improve performance. 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. But the key to that statement is the term “high-performance”. At a time when many CD players are little more than an off-the-shelf transport option, bolted onto a multi-input DAC, the reputation of optical disc replay has suffered significantly.
