Is There Any Reason To Buy A Reel-To-Reel Machine Nowadays??

Looks like others are selling it ...

This is one of those "Because I want to" moments, and there's nothing wrong with that, but unless you have lots of tapes that you really want to play that can't be duplicated any other way (if you taped simulcasts from your stereo or when they played full sides without interruption, band tapes, your kids or parents talking on them), I'd say no unless you really want to.  NOS tapes are expensive, prerecorded tapes are, what, 40-50 years old?  Every time you play it you lose a little bit of the information, finding someone who will work on it and, more importantly, finding parts for it gets exceedingly difficult, the noise level and dynamic range aren't quite up to snuff with today's offerings, worrying about the dreaded tape-eating monster showing up and so on.  I've read of people who really prefer their RTR in place of other sources but me myself never went down that rabbit hole so I have no stake in pursuing that.

Nothing like spending the cost of an entire season of concerts on one album, that you probably already have multiple copies of.  Rich fool's hobby reel-to-reel is (says Yoda).

Maybe not as good as R2R, but I regularly still use my two Aiwa 3 head cassette decks. I use them to listen to my many pre recorded cassettes, as well as taping from Fm radio or from lp's. I use them not only because they sound great, but because they are fun to use. Never sought out a R2R, due to costs and unfamiliarity. Cassettes are much cheaper and easier to come across, both blank tapes and pre recorded music. My decks are the Aiwa AD f770 and f660. Also have a Nak bx100, but it's apart to replace belts and idler tire.
