I have too many DAC projects!
Twisted pear Opus DAC board (Version 2). Thus is an assembled board using the Wolfson WM8741 chip. It has balanced voltage outputs so no I/V stage required.
Information and a picture here;

and there's a thread about it here;

You'll need a couple of 5V regulated supplies and a means of getting I2S data into it (maybe a RPi streamer or, if you prefer spdif, something like the TPA transciever http://www.twistedpearaudio.com/digital/wm8804.aspx)
£25 shipped within the UK

Hi Ray, am I right in thinking this should support up to 192kHz/24bit (with the right USB to i2s interface) ?
Cheers.

Outputs are differential voltage - no I/V required.
