Very interesting, Tom, and thanks for the link to the Oryx website - wow! - a goldmine of (presumably) pre-HIP baroque recordings (which is just fine by me!).
I had quite a few Oryx LPs in my collection back in the day..
Listening atm to Bach's Partita #1 played by Derek Adlam on a Feldberg Harpsichord.

It sounds good even if it is MP3.
The label that the Stravinsky Rite is on is Onyx, though, not Oryx.
