Oppo 105 D vs. DAC-transport combination.

To my great dismay, the more I listen, I’m finding my Oppo 105 is outperforming a very well thought of DAC and transport combination for which I paid 3x the price.  Basically the sound stage is wider and better defined.
Both the DAC and transport are less than a year old.  I thought I was upgrading.
Played by itself, the DAC-transport combo sounds great.  Until I compare it to the Oppo. 
I can’t understand it!

It’s the jitter on the S/PDIF coax output of the Oppo:

The same jitter will not be experienced when using the internal DAC.

It can be fixed and even improved however:

If you add a Synchro-Mesh reclocker and a good BNC coax cable, the Oppo jitter is reduced to ~7psec at the end of the cable, rather than the 800psec of the Oppo and cable alone. More than 100X less jitter. You will not find ANY transport with jitter this low.

Jitter is ALL that matters in a digital source.
