It all depends on the DAC. The idea behind my mod was to transfer the critical timing components out of the Touch and into the DAC. The amount of jitter depends entirely on the clock signal at the DAC chip input. There is no theoretical difference in using I2S or asynchronous USB (EDO) to convey the data, since in both systems the clock is generated by the DAC and the Touch timing is slaved to the master clock in the DAC. In either system, the Touch is simply presenting the data to the DAC, and the DAC itself is clocking it in at its own rate. I used I2S because that is the format my DAC chip prefers. In fact, one could use a cheap device like the raspberry pi running Squeezeslave, and if it is clocked externally by the DAC, it should sound the same as a Touch.
