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!

@ OP,
something seems to be wrong with this situation:
What ICs are you using? AES or SPDIF or Toslink out of the Oppo?
What power cords are you using? Did you A/B the Oppo vs the Cyrus/Schiit with the SAME ICs ? the SAME Power Cords?

Same question for the Cyrus/Schiit combo. 

Unless Oppo has made gargantuan changes to the transport of the 105 over the 95. I had the Oppo 95, the transport on it was mediocre at best.

ICs are Morrow Toslink between the Cyrus and the DAC, Morrow MA4 out of the DAC to the preamp, MA 3 between the Oppo and the preamp (RCA’s).
Stock power cords on both Cyrus and Oppo.
Morrow MA 4 power cord between preamp (Currently Emotiva XSP1, while my Conrad-Johnson PV11 is out for repair,) and Nuforce (Reference 9 V3) mono-block amps.
I have the Oppo 95.  The 105 is light years better.

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.

I recently sold my Oppo 105 after my 205 arrived. I swear within the last six months the 105 was sounding SO GOOD! Could it take five years to break in?

Dweller,

Are you saying you liked the 105 more than the 205?
Important! because I’m seriously considering getting the 205.
