![]() ![]() Our xmos combo can use the same output ASIO: foo_dsd_asio in foorbar2000 to play PCM and DSD music file. The DSD sound volume is controllable using our xmos DSD combo in all USB audio 2.0 compatible OS including WIN/MAC/LINUX system volume mixer.Ģ) Do I need to switch ASIO driver everytime when playing between PCM and DSD music file? I find it's annoying to do it when using the other famous brand DSD USB output adapter. Please notes there are many so called bit-perfect device can play DSD but you must set the computer master volume control to full volume.ġ)Does the volume is controllable in WIN/MAC/LINUX when playing DSD using this combo? I find that I cannot control the DSD volume when using the other famous brand DSD USB output adapter DSD audio as well as PCM audio can also be bit perfect volume control easily from the computer. ![]() ![]() This USB DSD DAC: Complete Bit-perfect at any volumeĬomputer -> USB -> XMOS -> I2S(audio data bit perfect at any volume)+IIC volume control -> DAC Chip (es9018/cs4398/pcm1794 etc.)Īfter many hours of work on customize the xmos firmware on this USB DSD DAC, audiophiles can move the volume control bar up and down freely in the computer volume mixer panel and still enjoy bit perfect audio. General device on the market: "Partial" Bit-perfect only at full volumeĬomputer -> USB -> XMOS/CMxxxx/AMxxxxx -> I2S(audio data scaled/altered if not at full volume) -> DAC Chip (es9018/cs4398/pcm1794 etc.) If the volume is not set to maximum in the computer, t he audio data is scaled/altered before sending to the DAC chip and the result is signal to noise ratio seriously affected. Most people may not notice many so called "bit-perfect" device on the market is bit-perfect ONLY When You Play At FULL Volume. The most distinctive features of this USB DSD DAC is our customize firmware for bit-perfect volume control. This USB DSD DAC combo includes XMOS USB to I2S with three ultra low phase noise NDK2520SD oscillator PCB, CS4398 DSD DAC PCB and an optional LED sampling rate indicator PCB.Īpart from the DSD playback functionality, it uses low noise thin film resistor, C0G capactor in the LPF, WIMA decouple cap, panasonic low ESR aluminum electrolytic capacitor and optimized layout 2mm distance for all decouple capacitor, etc. It features DSD playback, low clock jitter sensitivity and advanced non-decimating software volume control. CS4398 is the flagship model of Cirrus Logic who acquire Wolfson Microelectronics. ![]()
