![]() 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 Windows/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 lossless I2C DSD and PCM volume control. *High performance and compact DSD DAC solution for everyone. *All SMT component are soldered, some thru-hole component are not soldered. *When the ES9018K2M PCB used with our customized I2C control firmware XMOS USB PCB, extra features include a simple jumper(labeled SPDIF ON) to switch between SPDIF(labeled SPDIF IN) and USB input, bit perfect volume control as well as DSD/PCM playback in foobar without the need to switch ASIO driver everytime. (This ES9018K2M DAC can also be used standalone to receive SPDIF directly, the 3.3v SPDIF should be connect to the 20pin header labelled BCK and GND) *The single ES9018K2M DAC PCB can be used individually with only 3 wire I2S signal connected from Raspberry Pi, BeagleBone Black, cm6631a, amanero etc. T he USB DSD DAC combo includes XMOS USB to I2S PCB, ES9018K2M DSD DAC PCB and an LED sampling rate indicator PCB. ![]() This ES9018K2M PCB uses ultralow phase noise NDK NZ2520SD 80Mhz oscillator with optimized layout( 2mm decouple capacitor distance) and selected high quality components( 0.1% low noise thin film resistor, C0G capacitor in the LPF, WIMA Film capacitor and panasonic low ESR aluminum electrolytic capacitor etc), it can playback upto 384khz I2S/DSD128 input asynchronously with OSF on and no unlock problem. It includes the same Patented Time domain Jitter Eliminator used in ES9018 and latest PLL enhancement. ES9018K2M is the new flagship model 127dB DNR -120dB THD+N of K2M series from ESS technology who also make the renowned ES9018.
