In an excellent Lanner Chronicle blog post from Oct, 2020, an Aphex Twin quote, re-posted from Soundcloud, reveals that Richard James used a Sony DTC-1000ES to back up some of his early cassette tape masters:

“how i got the recording qual this good on cassette is a mystery to me now, lots of trial and error spose, not sure how those cassettes would sound these days, safe to say that they wont sound better but i could do the transfers better and ADC’s are much better these days, so dunno, swings & roundabouts. i encoded this and loads of others onto DAT about 25 years ago, when London records lent me a Sony DTC 1000 for 2 days around 1992 and i quickly backed up as much as poss [lucky i did] as well as giving them pacman 🙂 Back then there was no way to backup a recorded song, no way at all !!! think about that you youngsters, sure you could record it onto ANOTHER tape but it would always sound terrible.

So I used to get ver paranoid about my master tapes…i kept them in military water proof boxes, still in them now, most of em, not all. I’m actually getting progressively worse at keeping my stuff safe now . But then DAT came along to save the day, even though they pretty much always glitched on me, some of my mates got lucky with them, i thnk i was just in too much of a hurry and didn’t treat them very carefully. I went through about 10 DAT machines, portable ones, big ones, never liked any of them really. I bought a £7,000[new]DAT machine last year for £50, recorded beautifully until i dropped it 30 cm onto a carpet, but the thing was so heavy it totally broke, bugger,slipped out of my hands!”

Note: it appears all Sony DTC-1000 recorders are "1000es" models, and the 1000es is the item shown in the post.
