Depends on multiple things:

I assume it is a master tape copy

1: Age of the tape

Some type of tapes are pretty much dead after only 40 years or less. I had recordings from 1946 in pristine quality, as well as different tape from the 80s that was sticky garbage. Storage conditions are important.

2: Type of tape

Above point is influenced by type if tape, Ampex, BASF or others are very different by charges or batch/year.

3: What playback machine you use is a heavy influence (tape playhead).

If you use a Studer or a Uher or other tape players makes a big difference. I had a tape archive with some special formatted tapes to digitalize and the Studer was lightyears ahead in quality when it came to the more exotlc formats like dual mono recordings.

4: Last but not least the sound system/headphones and your ears at the end!

If you have more questions just ask, I work for one of europes last Hi-Fi master tape and hi class vinyl (180g vinyl) distributors and had countless vinlys and master tapes go trough my hands and ears.

Where did you find that one?
