LS50 and Classical

Hey everyone. I purchased a pair of LS50's (the originals, not the Meta's) about a year ago and my impressions are somewhat mixed. On rock, pop, jazz, blues and hip-hop they generally sound great. But 80% of my listening is classical and I find them somewhat 2-dimensional with the vast majority of my classical collection.

I don't have the space for floor-standers but I'm wondering if anyone has a recommendation for a bookshelf / monitor speaker that will give me more of the 3-dimensionality that I'm looking for. My budget would be up to $3000.

Other equipment:
Schiit Freya S Preamp (running balanced to power amp)
PS Audio Stellar S300 power amp
Denafrips Ares II driven by Volumio
