@doufthebiker,
Afterdark in HongKong has a whole range of performance packages including cables, other good clocks (albeit much more expensive are Cybershaft from Japan, Antelope Audio and Mutec. I concur with @lordmelton on at least reclocking the Dac and -if not using asynchronous USB the server. Obviously 10m clocks only work if your equipment has masterclock inputs. Wordclock inputs require stepping down the masterclock signal, eg Mutec. I use BNC cables from Shunyata (expensive) and Sommercable in Germany.
