High value, giant killer speakers?

I’ll put my hat in the ring here. I find in 43 years of listening, that my fav is RBH Sound. I’ve owned systems in the  TK, MC, Signature Classic, SX and SV series. For AV, my SX-T2/Reference has little competition. But for two channel listening, my new pair of SV-61 that use the beryllium 6.5” woofer and AMT tweeter may be the finest speakers I’ve ever heard. They are a “poor man’s” Voca Fina. Incredible. 

Doesn't the SV-61 use an aluminum cone and a silk dome tweeter??

Any thoughts on Usher audio's newer TD series? Looks really interesting with their diamond-metal-diamond tweeter and midrange units. Some of their entry floor standers can be had for under $5k.
