Indeed, it was a Revox / Studer that I was initally looking to buy. But 2nd hand condition for the few models on offer, and the lack of parts, was my primary concern with those.
I had unidentified songs that I hoped Shazam / SoundHound could take a stab at, as well as some sample of the families' voices as children, so I thought a temporary high end purchase might provide the best resolution for this task - and it did. I choose the Nakamichi MR-1 Professional.
I broke out all sorts of mix tapes etc and spent a couple of days sorting through them. And once I had done that, and experimented with modern recording to the format, I was left holding a baby, so to speak. Nice to look at in the rack, nice to show off to fellow audiophiles, but of little use when a DAT/DCC would have done it so much better, and have been a nice thing to record from the streamer with in the long term.
I tried asking around friends / family for what cassettes they had for me to have, and it seems they all made it to the charity shop, quite some years ago. Shame.
