2020matters:
I had a HiFi Rose 250A in house and compared it to my own Oppo 105-Darby.
The HFR DAC was clearly superior. It took only a minute to hear the difference. First thing to jump out at me was the 250A’s greater detail & transparency, amd a moderatlely more spacious soundstage. I didn’t hear the "crispness" that some people ascribe to the HFR DACs -- just increased detail without edginess.
I wouldn’t consider either DAC to be anything like SOTA, of course. But the 250A was clearly a step up/ The Oppo's internal DAC was pretty good in its day, especially in its price range, but it's now pretty old.
Hope this is still helpful.
