Portypop - I'll try a second time:
I2S is the bus most commonly used to drive modern D/A chips.
I2S is comprised of:
Master clock or MCLK - 256fs
Bit clock or SCLK - 64fs
Word Clock or sync - fs
Serial Data
Fs, or sample rate frequency is generally 44.1kHz for ripped CD files and 96kHz for master tapes.
In older DAC's, the Word Clock was used to clock the D/A conversion, but most modern DAC's use bit-clock. Master clock is generally used for digital filtering.
Word clock is the lowest frequency, so it is more easily used to synchronize the various digital devices in a recording studio.
For reducing jitter, reducing word-clock jitter is not that interesting. It may have a small improvement in some systems, but the bit-clock and master clocks are the ones that affect the D/A chip most.
