It reads CD, single-layer SACD, multi-layer SACD, and MQA-CD, and delivers true DSD output over I2S along with FPGA-assisted I2S offering ten pinout modes for flexible pairing. Because it is a transport with digital output only and no built in DAC, it produces no sound on its own and is designed to be the source in a separates system.\u003c\/p\u003e\u003cp\u003eDesign centers on a classic top-loading mechanism with a traditional disc clamp and fully gapless playback, which appeals to listeners who prefer a hands-on, ritual-driven experience with physical media. A 3.4-inch touch screen handles control and information, while a 25VA Talema transformer feeds the internal circuitry. Digital outputs include Optical, Coaxial, AES, and BNC carrying CD at 44.1 kHz and SACD DSD64 via DoP or D2P, with the I2S output supporting CD 44.1 kHz and native DSD64 SACD.\u003c\/p\u003e\u003cp\u003eThis transport is for the enthusiast who has invested in an outboard DAC and wants a dedicated, well-engineered disc source that can pass DSD in its native form.
