R2R Ladder DACs or All in One Streamer Solutions


I am soon to own a Pass INT 25 integrated amp. I also own an Oppo 205. 

I am now searching for a separate DAC to replace/improve the DAC in the Oppo.
Budget $2k. Used preferred.

I like the R2R ladder sound and want a tube inside for a little balance with the Solid State gear.
My current source is the Oppo 205.

I am also shopping for a Streamer/Ripper/Storage device. Roon friendly and DSD capable.
Budget also $2k. Used Preferred.

It seems that the few offerings of these all in one solutions all contain a DAC.
My thought is that the DAC included will not be any better than the Oppo so it is of little use.

Has anyone been down this road lately? 

Am I missing something?

Thanks in advance for sharing your experiences!

How did a DAC that was way behind the times 30 years ago (TDA1541) magically become good?

As we know, the Philips TDA1541 and TDA1540 "16-bit" d/a chips were used in hundreds of different acclaimed CD players. It’s sonic signature is still considered to be "musical" to many. Some DAC designers went back to it, and so did a few diehards buying up the old CD players.

Last year I demo’d a topic shelf 24 bit perfect re-clocked studio DAC at 3x the cost, installed +high end coupling caps in my 16-bit MHDT Orchid (stock TDA1541a chip), +a really good tube.  It wiped the floor in terms of enjoyability and musicality in my system. Same thing with a 16-bit Audio Note DAC.  Could not listen to the highly acclaimed 24-bit perfect DAC for very long. Found it to be dry, boring, fake sounding, not engaging, YMMV.
