This has been bugging me for a while now...
What is the mysterious chip beside the two crystals and how does it make use of both crystals?
An externally hosted image should be here but it was not working when we last tested it.

If I were to guess, I would say it is for clock recovery. One crystal oscillator is probably a multiple of 44.1 kHz, for CD sample rates, and the other is probably a multiple of 48 kHz, for PC sample rates.
I could make a more educated guess if you could state the name of the chip and the frequency of the crystal oscillators.
This looks like an interesting DAC, do you own one or are you thinking about buying one?

I do own it. The manufacturor had sanded the square chips to conceal their identities.
I was wondering how the two clocks are used; how does the system auto-detect and switch between them.
Then today, out of pure coincidence, I stumbled across AK4115 which is a SPDIF receiver with support for two crystals as well as both asynchronous and synchronous modes.
