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!

If you must know one of the no name Chinese was a nude TDA1541 complete made board from ebay for around $100 all it needed is a power supply added, the owner mounted it all on a block of wood!
Get off your racist pulpit sunshine, of course the Chinese are extremely capable, just like anyone, just look at a few these days Holo Denafrips, etc etc
T'aint racist to critique Taobao DAC offerings - I've bought plenty and implementations in general are poor. You did specifically say 'no name' and now you've introduced names. I would agree that the named guys do a much better job than the el-cheapo Taobao DACs designed by spare-timers. Early on there was one called 'raindrop_hui' but that was the name of his reseller - he was relatively clueless as regards EE but that didn't stop him selling tons of TDA1541 DACs.
Even "cheap" no name Chinese DACs.  There was never anything remotely racist in what I said. Stop dog whistling to hide you lie. By using the comment "cheap no name Chinese DAC" you are showing yourself to be the real racist. I will go out on a limb and say I have far far more experience dealing with Chinese companies that you ever will. 你说的任何语言都不诚实

False - rather racism is shown by projecting it onto others in the absence of evidence. Which @georgehifi did do in this case so my conclusion is the same as yours.
