I've been making my own DAC's since the mid 90's. For the last decade or so, I've been feeding my various audio systems with an Airport Express from iTunes. I use TOSLink on my DACs. A few years ago, I made a semi-modern DAC to replace my tube based DAC from the turn of the century (I've been wanting to say that for a while now). Here's my latest DAC:

It uses a CD8416 decoder chip to get from TOSLink or SPDIF to I2S. I then have an Asynchronous Sample Rate Converter (CS8421) to deal with jitter issues. Finally I'm using a CS4398 DAC chip which feed a pair of nickel core Lundahl LL1690 output transformers which act as the output stage. IT's a very good sounding and music DAC.
I'm planning on refining it to allow a rPi to be plugged in and powered to it as a daughter card. Any interest in this project.
