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!

@geoffkait - In the late 90's, Sony bought several special Rockport transcription turntables at something like $80,000 each. It was assumed they would be used to copy vinyl where the master tape wasn't available or in proper condition.
Thanks for the info. Most of my original customers had the Rockport turntable but it wasn’t a transcription type but it did have a dedicated isolation platform. The version that came out in 2000 went for $73K. I participated in a (big) room at Las Vegas with Rockport Hyperion speakers. EMT had a transcription turntable, maybe that’s the one.
many SACDs are ADD. Like the very famous Mercury Live. I can hear the poping noise from SACD. On the other hand, a modern multi-bit remastered 44.1k/16 bit PCM sound as good as 2.8 Mk/1bit SACD. Vinyl is just like film camera, it is for hobbyist now. I digitized my CD collection and everything is in the cloud or on hard-disc now. No need to sort CD anymore.
ADD usually means the original source was tape. All the famous Mercury’s were recorded on tape. CDs and SACDs of the famous Mercury’s are all from tape. Ditto the famous RCAs.
Amazon now selling the famous RCA recording CD boxset #1 and #2. there are the recordings by the very excellent musicians. I also bought same SACD so basically a duplicate of the CD but in DAD form. But Tidal allows me to to explore more new generation artist with better recording technology. I also like the dynamics of classical music. Think about upgrading speakers and amplifier. As far DAC, I got the recent 205D which has built in DSD/PCM/MQA DAC.
