The closet I've come to tape is cassettes, so no real familiarity -- heh. My sense is that good tape of top performances is expensive and hard to come by.
relatively yes. the tape stock itself on a metal reel for 30 minutes of tape is $60-$90. most albums use 2 reels. and quality dubbing is real time, nothing efficient. so labor intensive. lots of tape is grey market (you need the secret handshake), and so variable in quality and typically provenance unknown. i am very selective and always compare tapes of popular recordings to my vinyl to judge it. if it's better i buy, if not pass. commercially available tapes are mostly from either 50+ year old recordings, or new one's are of marginal performances. so one has to sift through them to find the gems. there are some really fine current recordings such as Ultra Analog for small combo classical and International Phonograph for small combo jazz that have high standards for sound and performance.
Experts are required to maintain players.
true mostly. especially the master recorders. but experts are out there if you look. i've personally not had any problem with that myself, but my 'experts' were mostly really smart and talented guys (Ki Choi and Andrey Kosobutsky) who i got started into tape a decade ago, and they became the most knowledgeable people. maybe i made my own luck.
not really. in my 15-16 years and around 250 titles (most 2 reels) i've yet to have a tape break, or wear out. but i do not play vintage tapes, only modern formulations. once i did acquire a small collection of vintage masters and they were a mess. so i divested myself from those and not gone back. it takes experience to be able to get a workable dub from vintage tapes. a special skill. not all vintage tapes are fragile, but most are.
my tape decks have been mostly the Studer A-820, which has the most gentle transport, and the Ampex ATR-102, also very easy on tape. so having a really well sorted out transport makes a difference on how a tape holds up over time. early decks are much harder on tape than later decks.
Tape copies are like unremastered reissues.
most master dubs are from production safeties so are the final master and not work parts. but i do have a few with extra passages in familiar tunes which were not the final product. those are fun and a generation fresher.
Mike, is any of that close to correct?
tried to answer the best i could.
