Cornwall IV vs. Volti Rival, Razz; Razz v. 1, 2, 3 -- what changed?


Looking for efficient speakers. I had the opportunity to listen to a Cornwall IV yesterday. It was run on nice tubes (Primaluna 400 EL34s) with a bluesound node streamer/dac.

QUESTION: I'm curious if anyone has compared CW IV with Volti Rival of Razz. Thoughts?

QUESTION 2: Anyone know what changed in the Volti Razz when it moved from v. 2 to v. 3?

Thanks

Just purchased Memoirs Of A Geisha Original Soundtrack LP.  Big fan of John Williams, Yo-Yo Ma and Itzhak Perlman (saw both live at the symphony).  @silverfoxvtx1800 -thanks.

I will need to check those out my friends. Count me a fan of Williams, just have yet to buy.. I’m open to any suggestions you guys have. Last night I was listening to Thundercat Drunk and Sketches of Spain in mono. ( to me the mono sounds better, hard to put into words why) My Volti with my Cary SLI80 sounded sublime.
