Has anyone ever heard these speakers by Volti Audio?

Yes, BMS

I heard them at a show last year.  Marvelous speakers, with no horn colorations that I could hear.

Listened to them at the 2015 NY Audio Show paired with a Vinne Rossi Lio, Palmer TT, and Vinnie Rossi Amp. Clean and clear at high volume but lacked the emotional involvement I look for. They didn't draw me into the music, just presented it in a "matter of fact" way.
I second the Charney recommendation for and involving horn that plays music not just sounds! AFAIK Charney will be at the 2017 Capital Audiofest.

Disclaimer: I have known Charney since '05 (bought a used Dac from him) and own a pair of his creations.   

Have a couple of days on the Rivals. In my system/room I'd have to say that there is great emotional involvement and musicality.

Still very early in my time with them. More after a few days.

I would love to hear the Simon Mears Uccello speaker (10,500 UK Sterling) which similar(ish) to the Vittoria.
