Yup, another one. The SOtM dX-USB HD Digital Audio Transporter DDC is a ~US$500 box that converts USB to S/PDIF. With offerings from M2Tech, MHDT Labs, Audio-gd and Audiophilleo, this (low-rent) market space is really hotting up.
The dx-USB HD box is externally powered and handles USB data transfer via the much-vaunted asynchronous method – up to 24/192 (so native on OS X but bespoke Windows drivers will be required). Outputs are AES/EBU, coaxial and optical.
Most impressive of all, it’s specified as having two distinct oscillators for 44.1kHz and 48kHz sample rate families.
Wot no I2S? SOtM already manufacture the SOtM dX-USB USB Digital Audio Transporter DDC (also ~US$400) that trades AES/EBU for I2S, 24/192 for 24/96 and asynchronous for adaptive.
SOtM? “Soul of the Music”. An opportunity missed: given their South Korean location, they shoulda called it “Seoul of the Music”.
