I just heard this combination yesterday. There was a definite improvement in the sense of real insruments and voices in space, and diminished "splash" on transients like cymbals and applause. The character of the sound changes less than what you hear when switching between the DSD and multiple-bit DACs, but whereas I think the DSD/multibit choice is a matter of preference, it's pretty obvious that the clock's impact is better, vs. just different.
I'll take a stab at quantifying the impact, and say that the effect on redbook is about 25% of the way from redbook to SACD, possibly a bit more.
I also listened to the $5k model ( G03X), and this much less expensive model is very nearly as effective. I didn't try to compare clocks to each other because frankly, I can't afford the G0Rb unless I win the lottery. As far as the G03X, if I had the cash, I would taken one home, but alas, it will have to wait . . .
