Stellavox ST2 DAC and use of worldclock generators

Hi

Anyone used this? I am quite keen to buy a Victor XL-Z999EX CD (japan only version of the Harmonix Reimyo 777 cd) with world clock input function to reduce jitter and get the timing correct.

So...i've seen a Swissonic WD8 world clock thingy...and also a Stellavox DAC.

The Stellavox ST2 has received many excellent reviews in asia, apparently based on the Goldmund Alize2 technology.

Wondering how this would compare with the Benchmark DAC for example?

On the other hand if anyone knows of single channel world clock generators i would be very interested to hear. The Swissonic (i have growing suspiscions that they might be related to Goldmund and Stellavox but its only a hunch) WD8 is 8 channel and for studio use you see!

Cheers
