Toe in might soften some top end depending on off axis response.
Older CD players can definitely benefit from an external DAC
I have an MF A300 with a pair of Dynaudio Audience 82 that I bought new and used everyday for about 20 years. I thought it was a great match, but it’s hard to hold off the itch indefinitely. (20 years is pretty good though) I recently upgraded “everything”, but I haven’t been able to make myself sell any old equipment yet. There’s a fantasy of a 2nd system (that I doubt I will ever use).
