That was just an experiment, and to make sure it wasn't a waste, I down-loaded it to hard-drive; those were my most select LP's.
As you know, new tape can be recorded over at least once with no ill effects; consequently, I'm regarding that as blank tape when the need arises.
While the playback sounds good from the computer play list, I'm wandering if I would get R2R quality out of the playback with a very good DAC?
Yes, 15 IPS is extreme for LP's, but only because of the expense and time. Even if I could afford the expense, the time would be too short; but if I could find a way to negate those two factors, I could easily live with 15 IPS for my most select LP's, not just any LP.
