Why no interest in reel to reel if you're looking for the ultimate sound?

technically you are right on.  better yet, get 1" master capability.
problem: software. end.

Like vinyl, it's an expensive proposition if you don't have the media already. 
As far as sound quality goes, on a good quality machine it competes remarkably well with ANY other format . Machines are available and so are the good techs to keep them going.
Won't argue the tapes are expensive, but the OP refereed to sound quality, not so much cost.
Oddly enough, don't some of the same detractors and cloons spend as much on "Hot Stampers" ? 

Tapes are expensive but they can be multiplied and shared among friends.

The kick A tapes start at half track high speed and IMO a B-77 Mk3 with some mods. I have two. There are of course other decks. Service is sparse and getting worse unless you live in the three remaking tape Mecca: LA , NYC, Nashville, maybe Memphis...

the LiL A-77 can as Eric notes be formidable- a few well chosen mics, small really transparent mixer ... and you might end up w The Band backing Dylan on the Basement tapes.

it is actually a critical listening path I recommend, but ya need a budget, a few really good microphones and some vocal and or instrumental talent - make your own reference recordings and be there for the original event :-) get a good A to D ( Ayre made a superb one ) and you might able to speak w authority on digital vs tape.

have fun, enjoy the music.....

The Sheffield D2D also include some smoking hot horn work by Harry James - strongly recommended 

While not to everyone taste, the artist in question is Dave Grusin - certainly a guy with chops. I would ignore the ego trip peanut gallery.
