I haven't heard the Auteur...hope to at NYC CanJam in February. However, I have experience with two R2R DACs, both by Audio GD: the NOS 19 (my day-to-day DAC since mid-2016); & the DAC-19, the oversampling version of the same design.
Re sonics, all I can say is after epic burn-in (some claimed up to 500 hrs burn-in is needed before the sound stops changing--this proved correct), the NOS 19 quickly changed how I hear & think about digital--as in, I no longer think about it at all. It just sounds like music. The DAC-19 isn't quite as effortless & natural as the NOS 19, but pretty close (way better than d/s designs I've heard).
Recently Audio GD retired both units, though I believe new ones can still be purchased from Magna HiFi in the Netherlands (I bought both DACs from Jos@Magna HiFi...excellent experiences).
If you don't want to buy new, there are usually some DAC-19s F.S. here or elsewhere in the $600-$700 range. You rarely ever see NOS 19s F.S.
I've heard both my Ori and a friends' Eikon pretty extensively on the NOS 19; they both sound very good, indeed. So I'm guessing the Auteur would, also.

- FYI, some regard NOS as a warmth filter & say it lowers resolution. All I hear is good sound, but YMMV...
