CDs when played back on a top notch player or a transport fed into a good dac sound really good. As a matter of fact trying a very modest transport, Audiolab 6000CDT, into my Bricasti M3 DAC was the driving factor for my streamer upgrade. I just couldn’t stand listening to the built in network renderer Roon endpoint. One of the biggest differences was how articulate and engaging the CDs were. Yes there are potentially different masters on Qobuz and not necessarily the same as the CD and you can hear it in the mix but the emotional engagement aspect wasn’t comparable no matter how many songs/albums from Qobuz and Tidal I compared to CDs.
Don’t you love it when you ask for advice and you get a response claiming that you’re pretty much delusional because what you hear, none of that is real, it’s all in your head. The details, transparency and depth is all confirmation bias. Or your dac is not entirely immune to jitter. Or it is both confirmation bias and your dac sucks.
In your case the Accuphase machine is top notch. It’s going to be an uphill battle for the lesser streamers to reach or beat the baseline set by the DP-67.
Stay the course. Don’t let any of this sway you away from trying a good streamer. It might take some more time and a bit more funds to get to that level but once you do, you will probably never play another CD again unless it’s a rare album not available on streaming services (you can also rip those to a nice SSD and enjoy playing those local files thru your streamer)
