Dolby-free early stereo recordings sound best.


This is an old controversy, but still significant with today’s digital re-issues.  
Dolby was invented to remove dreaded tape hiss from hi-fi reproduction.  The problem, despite claims to the contrary, is that it also removed the high frequency partials that produce the “magical” illusion of real space.
The magic is  especially evident in digital transfers of tapes from the pre-Dolby period of the late ‘50’s and early ‘60’s.  There is an openness and airy quality to these recordings that are unmatched in tapes from the later, Dolbyized, period. 
This is an observation that not many others have ever commented on, to my surprise.
I listen mainly to classical, but I would be interested if others had  noticed this phenomenon in classical or other genres like jazz, rock or pop etc.

We had the first dolby A units in our studio in chicago. After several months of use none of us liked them and stopped using them. Most studios instead went to 30ips recording

I assume the 30ips was not Dolbyized.
OP -

The same was true for Dolby Surround films. They actually used Dolby-A on the L/R optical tracks on top of a second layer of Dolby-B or C (can't remember) for the decoded surround channel. 

However! Based on my experience this was not on the encoding but the decoders. We used our own decoders instead of the Dolby-A cards and they had the best of both worlds. Low film noise and open/airy/immersive top end.

I suspect it should be possible today to build up an unofficial Dolby-A decoder digitally which is just as good.

Best,
