Default New XMOS USB DSD DXD 384k ES9018 K2M DAC with SPDIF INPUT combo

Hello everybody,
I just develop a new XMOS DSD DXD 384k ES9018K2M combo with SPDIF input.
The PCB uses ultralow phase noise NDK NZ2520SD 80Mhz oscillator with optimized layout and selected high quality components, it can playback upto 384khz I2S/DSD128 input asynchronously with OSF on and no unlock problem. (The original ES9018 requires 100Mhz oscillator for 384k playback with OSF on)

Features:
1) DSD and PCM is also volume controllable in the win/mac/linux system volume mixer with our customized xmos firmware for iic bit-perfect volume control.
Related paper on this:
http://www.esstech.com/PDF/digital-vs-analog-volume-control.pdf

2) one ASIO for both DSD and PCM playback in foobar2000, no need to switch in the preference every time for playback between DSD and PCM

3) No annoying pop sound when playing between PCM and DSD format

4) SPDIF input and USB input switch with a jumper easily.

the SPDIF input is a 3.3V input level 2.54mm space header, a Toshiba TORX147 optical receiver can be used for optical SPDIF input. For coaxial spdif input requires a few more component to translate the 0.6Vp-p to 3.3V level.

The same board with only i2s input would be really great for people that own exau2i or minisharc for their active speakers!

Any experiences with these boards?
It looks very promising especially together with new 1uV Ultralownoise regulators from diyinhk.

Hi diyinhk
do you have some measuments of this combo?
The final price od DAC + your Ultralow noise power supply is not low,
so i would like to se any result before i buy one.
Also if you can describe the differences in sound between your ES90023 and ES9018K2M.
I have now ES9023 DAC + discreet class A headphone amp and i want to make some upgrade.

Thank you

Michal

diyinhk has his own site wit e-shop

Audio Kits - DIYINHK

the ES9018K2M chip is 2 chanel only - new smaller version of ES9018
with a bit worse DNR (127dB) but should be much better than ES9023

here is comparison of Sabre chips
ESS Products - DAC
