I was a reel to reel fan from 1963 (first Philips 4 track 3 3/4 mono) to 2010 when I sold my last Revox A700. The last two Revoxes I had were superb and the A700 which was 1/2 track and did 15 i/s worked superbly. It was clumsy to cart around to concerts to do recordings, so eventually I got a SONY DAT recorder, model 2000ES, same size as an analogue cassette deck but gold in colour. Then one day at the Nassau Centre while I was in the kitchen making something to eat for the musicians during a jazz concert interval, someone, presumably from the audience, nipped on stage, unplugged it and stole it. No-one apparently noticed although there were 200 people in the audience, but not all seated at that time
It did work very well, with superb dynamics and utterly silent background. I think it did 16 bit 48KHz recordings
Another device I still have is a Panasonic VHS Hi-Fi deck. This uses I believe an FM type of modulation to record onto video tape. Very smooth sound, but not as good as the Revox
Strangely enough, one studio I used wanted open reel tapes so I would transcribe the DAT tape onto 15 i/s 1/2 track. There was a slight degradation I could detect, but only using an A/B comparison
