(clock recovery notwithstanding...)
i would think that such a "direct drive" approach would lead to lower latencies and jitter overall, as the I2S master clock is a function of the audio sample rate...
- uses isochronous transfer and audio clock is derived from USB transfer clock;
- uses bulk transfer and separate oscillator to generate audio clock;
- uses isochronous transfer and re-clocks the USB transfer clock for audio.
The second group has the lower jitter than other two (comparable to the pisound), but introduces other problems. More on that: http://thewelltemperedcomputer.com/KB/USB.html
The third group is kind of rare and very pricey, however it should have less jitter than the first one.
So long story short - yes, pisound has less jitter than the most of USB audio cards.
