Over-compressed tells you why Lp's and reel stuff always sounds better. I have a significant collection of pre-recordered reel tapes that were done for broadcast stations. The source of the recordings were lp's. Since these were done professionally, years ago, they still sound great. They were recorded and mastered without any compression, but they were often compressed when they were actually broadcasted. Most of the tapes are 7.5 ips, dual track quarter inch tape. I have compares some of the tracks of these tapes with their lp, cd and cassette versions and often the reel version sounds the best.
