I used the Dolby A tapes because they were the highest-quality master
tapes I had available for this purpose.
One tape was <gasp> made on a ReVox A77, the other was made on I
don't know what, but perhaps a Studer A810, but I do not know,
really. I no longer have the second tape.
Also the A77 tape was one I made and was intimately familiar with.
It's vinyl version received an excellent review in The New Yorker
among other places.
This is typical of my incoming tapes as I never know what they were
made on. By the way, the series of tapes I made on the A77 in the
1970s uniformly sound better when played on any of the three machines
in the shootout. It was interesting to hear the difference among the three.
