Compact USB powered converter built on the ROHM BD34352EKV chip with an XMOS XU-316 interface. USB-C, optical and coaxial inputs, a 2Vrms RCA output, PCM to 32-bit 768kHz and DSD512, THD+N of 0.00038% and a 119dB signal to noise ratio. Brand new, boxed, full manufacturer warranty. The SMSL D1 is a small USB powered converter with a single pair of RCA outputs. It is the straightforward answer for anyone who wants to get audio out of a computer, television or games console and into a proper amplifier or a pair of active speakers. It is finished in black. This is brand new stock, supplied boxed with the full manufacturer warranty by Dreamcrest Audio as an authorised SMSL dealer. What it does The D1 converts a digital signal to analogue using the ROHM BD34352EKV chip, with an XMOS XU-316 interface handling asynchronous USB. It accepts USB-C, optical and coaxial inputs, so a computer, a television and a disc player can all be connected, and it outputs on RCA at 2Vrms. Over USB it handles PCM to 32-bit 768kHz and DSD512, while the optical and coaxial inputs run to 24-bit 192kHz. The unit runs from the USB connection itself, so there is no separate power supply to find a socket for, and SMSL include a power filtering stage so that bus power is usable without penalty. How it sounds and where it fits ROHM converters are typically described as warmer and less clinical than the common alternatives, and the D1 follows that. Against the built in output of a laptop or a television the difference is not subtle, mostly in a lower noise floor and better separation between voices and backing. It is a good match for active monitors on a desk, for a compact integrated amplifier in a bedroom, or as a way of improving television sound before you spend anything on speakers. There is no headphone socket and no volume control, so pair it with something that has its own volume, or step up to the D100 if you need headphones.
