you can’t really know unless you hear it in your system
denafrips dacs are excellent, but a little bright amongst the r2r crowd, and according to my research, so is the holo springs unit (based on that i have ruled it out for my own use) - note also that there are various versions of the holo springs unit, they may have their sq differences too, dunno ... gets a lil complicated and hard to sort out as i was researching
the smoother school of r2r is sonnet/metrum, as well as border patrol and mhdt (though you can alter the tilt of their units with tube selection)
audio mirror is another one out there, but i have not had one in hand yet to assess
good luck
