+1 to charles1dad’s tacit nominations...that’s a good core of experts to start with. I’m sure there are others who will join in. Maybe even Frogman and Orpheus.

Use Jazz Aficionados as a template. Start a new thread (just as you did here) and "prime the pump" by naming some of your own favorite classical recordings. Details about composer/composition, orchestra, conductor, recording label, maybe even venue...all grist for the mill. Finding samples that can be linked to on YouTube - icing on the cake (if you will permit me to mix pump, mill and cake figures of speech in one paragraph).
c1d is right about Jazz Afic., but it started out with one single post.
