I don't have any tracks to recommend,
but...
I'm a bookshelf lover in a similar boat (needing to thin the collection). My choices aren't nearly as difficult as yours. Somehow, I let very few go, and just better organize 'em.
Moving right along...
- I'm newer to RBH, but always on the hunt. Have a pair of SV-61s pending.
- Have you thought much about posting videos / a YT channel?
- Lastly, I'm interested (as a collector) if you're selling.
