Please let us know.
I'm convinced the DAC-50 will do an excellent job. The overall result however will also be influenced by the other devices in your system (preamp, power amp, speakers, cables, room).
Accuphase did r2r in their DC-81 / DC-81L / DP-70 / DP-70V and then went for parallel multiple DACs based on chips.
The problem with r2r is, that you have to meticulously handselect all resistors in order to acheive good linearity. Just using low tolerance resistors without handselecting is not sufficient.
Temperature differences and ageing may further degrade the quality of the DAC.
That's why dCS chose another approach than r2r from the beginning (dCS Ring DAC, see attachement).
Upsampling allows to use less steep anti-aliasing filters and improves impulse response.
