Upgrade Belles 21a w/caps

Looking for input...I'd like to upgrade from my Belles 21a with auricaps and additional upgrades. I'd like to stay with tubes and pair with my Van Alstine Synergy 240 double amp. Speakers, Emerald Physics CS3 MK2 w/ a pair of REL T2 subs, source, OPPO/Exemplar Audio.

Perhaps an irrational direction, but I'm wondering what's out there for $1500-$2500. The Doge 8 Clarity, Rogue: Perseus, Cary: Constellation and the Jolida: Fusion modified are on my short list. All based only internet observations...Suggestions PLEASE!

Can I be convinced to stay with the Belles? Perhaps.
