Very nice Moon 100D DAC. Excellent sounding DAC - the only reason it is up for sale is I moved to a streamer out of convenience. Below is the information from the Moon website. Please reference photos for conditions and ask any questions! Local pickup in CT is available. $325
The MOON 100D Digital-to-Analog Converter accepts USB, S/PDIF and TosLink inputs. Intended for use with a computer via the USB input, the remaining inputs allow for interfacing with other source components such as a music server, digital transport, etc. All digital input signals are processed through an asynchronous sample rate converter and then 24-bit DACs.The 100D is housed in a compact chassis constructed of rigid aluminium and features a 1/4" brushed and anodized faceplate. Don't be deceived by its small footprint since trickle-down technology dominates, thanks in no small part to its larger sibling, the 300D ... Amazing things do come in small packages.
Using 24-bit/1.411MHz processing, the MOON 100D will faithfully reproduce your digital music in an effortless fashion. Accepting an input signal from 44.1 to 192kHz with a bit-depth range from 16 to 24-bits, jitter is a virtual non-issue thanks to the asynchronous operation of this DAC. Sonically, it portrays all of the Simaudio hallmarks: clean, powerful, fast, extended bass combined with an open midrange and airy extended high frequencies.
An important note about the 100D's USB input:
The USB input on the MOON 100D accepts a digital audio signal of up to 16-bits/48kHz.
