Much though I love reel-to-reel (like vinyl, it's a wonderfully 'tactile' medium, more 'involving' way to engage with your music compared to digital- much like keen drivers will always prefer a manual gearbox to automatics), but storing them creates a hell of a lot of bulk, not to mention that storage conditions ought to be appropriate to prevent deterioration. Plus the head better be kept clean!
An issue with magnetic tape is 'print through', whereby preceding or successive layers of tape wound round the reel transfer magnetic data via onto other layers. This could possibly be limited or eliminated by better quality tape, perhaps.
As for getting 'master tape' quality though, any pre-recorded tape that the consumer is likely to get is going to be, at the very purest, be a 'copy of a copy', but more likely many generations of copy away from the original studio master. And unlike digital, analogue recordings invariably suffer the further they are from the master tapes. Digital remastering can clean up the signal, of course, but my personal opinion is that such recordings can sound compressed and a bit clinical- compare an analogue-mastered analogue recorded Led Zep album to the remastered versions- some of the life and dynamics seem to have been lost.
I can see this product finding a home amongst audiophiles with a pre-existing reel-to-reel collection, as well as possibly home recording studios (as long as they are happy with just two channels, or want to do a lot of editing). I can't see it making waves amongst a younger generation used to digital- except maybe as a retro toy.

Tape is an awful medium for storing anything on - it stretches, oxidises and degrades.
Still, it's given me an idea for fleecing cashed-up retro-dorks: I'm going to launch a crowd-funded reintroduction of the medieval hand-cart and promote it as a 'purists alternative' to cars.

some issues- tape wear*noise and distortion accumulation*"head bumps"*bulk [the tapes take up nearly as much room as LP records, and the machines themselves are very heavy and take up lots of room]

@BartyLobethal vacuum tube amplifiers are making a comeback too

This is such crap. "Audio tape is the only format that can record and play back pure, natural sound in its whole and original state"...with tape hiss, motor wobble and variable head-to-tape contact. Not saying those problems can't be minimized by good engineering...but not at a cost any "consumer" will be willing to bear.
Sure, you can probably fool the bearded hipster crowd who bought into LPs last year and are looking for the next really cool thing to impress the Object of their Desires...but for me, a 38 year veteran of radio and television production...Revox, Studer and Ampex have all made better decks already...these guys don't stand a chance.

I'll take one please! I really miss my old reel-to-reel deck.

As they say there really is one born every minute! Tape is a terrible medium, stretching, jamming, noise, deteriorating with time etc. and I for one couldn't wait to get rid of it (both for audio and digital backups), even if the alternatives did cost more initially, now they don't)

Tape is way to delicate. I loved cassettes. There were some albums I had on cassette AND on CD, and yet the tape always seemed to better evoke an emotional response/connection. However, leave a tape in a hot car one day and kiss that analog quality goodbye.
Why aren't we focusing on the future of sound? i.e. Given the advent of 3d-printing technologies, new nano materials, lasers, and the discovery that DNA can hold information; I'm surprised we're not using quartz memory crystals yet, or a similar cartridge form that can hold Terabytes of data. Can you imagine listening to an ultra-HD digital master, with all of the tracks available to switch between/remix at will, with a read process that does no harm to the medium...and the medium is impervious to the elements and time?
Holographic sound!

When the coil in the tapehead reads a magnetic signal, passes through an audio amplifier and is sent through to a magnetic coil in a speaker to produce sound, there is a certain indescribable "rightness" that results that is quite pleasant to the ears. This is true for both records and tapes, but the record is more susceptible to deterioration by the nature of simple handling.
With a good quality deck, tape and storage, one can have a very decent audio, and the look of the big reels turning can be pleasant as well. I'm glad I've kept my 1/2 track Revox.
Today's digital audio is all about bytes and convenience and have a kind of antiseptic quality that can be perceived as clean and pure, but the intangible pleasantness of records and tape will always be there to the ones who recognize the difference. It's no wonder the formats are making a comeback.

Some of the comments sort of clump around the necessity for a "don't be an idiot" with your media disclaimer. I've owned RTR gear since the early '90's and while there were (not so much now) binder coating issues (especially then) I've had exactly zero problems with its ability to retain signal and remain stable. Digital has advantages, and it's better than it's ever been, but the thing it's continuously made to chase is analog, and there are good reasons for it. Overdubbing/Multitrack is where digital shines. For minimalist two mic, good preamp recordings, Analog's still (and likely to remain) "where it's at".
