The CH Precision D1.5 raises the bar for high-performance SACD and CD playback. Although high-resolution file replay has gained popularity, optical discs remain a trusted standard for digital music. In fact, with so many affordable CD and SACD titles available today, optical discs have proven to be a stable and evolving source. Consequently, a high-quality disc player like the D1.5 is essential for any high-end audio system.
Innovative design: The MORSe mechanism
At the core of the D1.5 is CH Precision’s groundbreaking Mechanically Optimized Reading System (MORSe). Unlike off-the-shelf transports, this mechanism is built entirely in-house. For instance, its nearly 1kg brass sled minimizes mechanical resonance, while its high mass counterbalances the disc’s torque during playback. Moreover, this ensures smooth and precise operation at all times.
To enhance stability further, four alpha-gel mounts isolate the MORSe mechanism. These mounts filter vibrations down to AC mains frequencies, preventing interference from both disc spinning and chassis vibrations. Additionally, the lightweight PEEK polymer disc clamp secures the disc, allowing slip-free motion. Meanwhile, the rigid 2kg aluminum chassis offers a stable grounding reference, eliminating mechanical interference effectively.
Flexible and future-proof playback
The D1.5 offers unmatched flexibility thanks to its modular design. For example, users can configure it as a CD/SACD player, transport, or both, depending on their needs. Its standard digital output board supports CH-Link HD, S/PDIF, AES/EBU, and TosLink connections, ensuring compatibility with a wide range of systems. Furthermore, CH-Link HD enables the direct transmission of high-definition material, such as DSD, to the C1 DAC or I1 Integrated Amplifier.
Additionally, the D1.5 is highly customizable. Users can enhance its functionality by adding mono DAC boards, which feature CH’s proprietary PEtER spline filter algorithm. This transforms the D1.5 into a reference-grade player for SACD, CD, and MQA-CD playback. To improve precision, the optional Clock Sync board allows synchronization with the T1 Reference Clock, while the X1 external power supply boosts overall performance.
Exceptional sound quality
The D1.5 ensures impeccable audio fidelity, making it suitable for audiophiles who demand the highest performance. Notably, its support for multiple formats, including stereo PCM, DSD, and MQA-CD, allows it to handle diverse audio sources. Moreover, the front panel’s dual concentric rotary control, combined with the CH Control App, offers intuitive and seamless operation. Furthermore, the customizable AMOLED screen lets users match the display to other CH Precision components, adding to its versatility.
Supported formats
- CD: CD, CD-R, CD-RW, MQA-CD (16-bit/44.1kHz PCM).
- SACD: Single-layer and hybrid stereo (1-bit/2.8224MHz DSD).
