Hi,
I tried to search forum but i did not find much...
Anyway, I ordered this one:
24-bit 384khz PCM NOS R2R high precision resistor network DAC fever level decodi | eBay
Now I want to put that card and a Raspberry into the chassi for my preamp. I also want to be able to connect a CD-transport and maybe some device to play FLAC-files from SSD or USB.
I am totally novice to these kind of signals, but I dont want optical signals. And as I understand it i need to have my signals in XCMOS-mode I2S(?). How is the easiest way for me to connect these device to my DAC with priority to keep high quality on the signals from CD and "FLAC-player"?
I found ways to connect, but that is thru HDMI. If I could avoid that, it would be nice. 🙂
Thanks in advance!
Regards, from Sweden

seems like it will accept standard I2S (most used 64-bit word length), so any existing USB-I2S based on xmos will work ... PCM2706 or CM108 solution will work up to 16b/48kHz
... now back to the DAC itself, they claim 24-Bit, but in the reality the precision will stop somewhere at 13-Bit at best and the rest bits are a mess 😀 ... for a 10-bit R-2R using even 0.1% resistors ladder is not enough ... for 16-Bit DAC the accuracy must be 0.001% ... so forget 24-Bit from that

16 bits only with 0.001% resistors in the R-2R ladder ...
It will play 24-Bits, but why when the precision ends in half of that ... the rest bits are rubbish 😀

Thanks for the reply.
So that it say that "does not support left-justified, right-justified and does not support DSD format" Is nothing I should care about?
This ctrl+c ctrl+v:
Signal input: 4-wire I2S (Philips IIS format) does not support left-justified, right-justified GND BCK LRCK DATA
Supports the highest sampling rate and tested PCM384KHZ to work normally, and does not support DSD format.
Has to be formuled as this:
Input signal: 4-wire I2S (Philips IIS format), as GND BCK LRCK DATA
other formtas as LJ, RJ and DSD are not supported
