I understand. But for me open reel deck would make perfect sense. I don't play most of my records entirely so I have to jump and move the needle. I would make compilations. Another idea, very difficult to realize, is to find master tape dubs of the performances that were never released. Just take a listen on youtube, there is a lot more than officially released material. Pre-recorded easily available tapes, in addition to being extremely expensive, is not the music that I would listen to, perhaps with a few exceptions. No, tapes won't live as long as records but you can play them hundreds of times without any signal loss. I would sell most of my records after making recordings, except most valuable. German Audiophile Society is said to be the best place to look for rare stuff, I bet you better have connections there, any way. Legally, it is probably very much a grey area, but in any case it is seller's problem.
