Open reel tapes were manufactured by high speed
duplication, for playback at 19cms (71/2 ips)
They had no NR, and the FR was typically -3dB
at 12kHz. The SNR was 50dB. This is
greatly inferior to the LP. Perhaps you could
not hear the difference?

There was some discussion within the industry about
selling reel to reel tape copies at 15 ips made in
real-time (as supplied to radio stations) But this
would have meant the use of NAB reels, which most domestic machines
cannot accommodate, and there was also fear about the
possibility of these being used to make pirate audio
cassettes. The cost too would have been much greater
than the LP.

PS Just had an e-mail. It seems that open reel tape
copies were also available in the US at 3 3/4 ips
on 5" reels. Now they *must* have been better than
the LP :-)))

They tried 3 3/4 ips open reel tapes near the end, and that pretty well
killed off the open reel as a consumer format. Been there, done that too.
It was pretty grevious.
