New speakers for $5000

Given your music preferences, I'd add the Spendor 2/3. Perfect for your room size.

Honestly, since 2010 or so speakers have gotten so much better you just need to focus on matching the bass output to your room. There's still a few designers that will use a hot tweeter to mimic the resolution of higher quality drivers and some do it better than others.

I would listen to the Linn M-150's
