Nice to see more details of your upgrades. We have, with respect to Linn, similar ears and minds. I too am on the upgrade path, and simply haven't found anything that I like remotely as well as Linn electronics. Some well regarded gear I've heard is much more expensive but at the same time so much less involving and musical. This stuff seems designed to give what someone thinks is pleasant sound, rather than real music.
The one tip I would give is keep your mind open to getting into vinyl. A Linn LP-12 can be had quite reasonably on the used market (though new, you are looking at a lot of money). For me, my turntable has opened up musical enjoyment considerablly. You will need your dealer to educate you about LP-12's, however. They are wonderful but fragile beasts.
