I like the concept of a one box solution as well (footprint, simplicity)
- Linn Hub edition DSM…lots of options for DAC as well as phone stage
- Moon 791 even has a phon stage
Ine box reduces system matching as well as reduces interconnects, power cables, etc.
I prefer to simplify when possible - though it does compromise future flexibility. Therefore I would use a well respected manufacturer who supports their products beyond when they are no longer sold.
