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!

Ideally the big advantage of the compact disc was its signal to noise ratio and dynamic range which all things being equal is much higher than what the best turntable can deliver. Let’s say 60 dB for analog and 90 dB for compact disc/player. That’s a difference of 30 dB, right. But everything is relative so when CDs are overly compressed Dynamic Range wise then it could even the playing field, it all depends though whether the record you’re comparing it to was overly compressed itself. But I tend to agree that subjectively on average to good systems records can sound more dynamic. There are also lots of Polarity issues with CDs, more than with records I suspect.
Getting back a little closer to the original subject, the three to two hole adapter that I got to enable me to connect the Cyrus to the DAC had the wrong size two-hole.  So, I’m back to the original dilemma of not being able to hook up a decent cable to the transport.
Writing to Cyrus didn’t do much good.  They, incredulously, praised the Oppo, and said the sound might be a matter of taste!

@geoffkait +1, regarding CD dynamic range compression. That robbed much of the life of CD playback.
