Tube amp to match sensitive Living Voice Speakers

I've had sage advise before and a little more would be helpful. I am pleased with my system and the last prospective change is a new power amp.
My System: Modded Shanling CDT-100
Origin Live Resolution/Illustrious/Koetsu Rosewood Signature
Creek T43 tuner
Conrad Johnson Premier 17 Pre
Pass Labs Aleph 3 power
Living Voice Avatar speakers
Acoustic Zen cables
The Avatar's are highish sensitivity, 94db and were designed around tubes and Kevin the designer is strongly pro tubes. The Aleph 3 is wondeful and I will keep it, but, slightly sweet, a narrow soundstage and lacks a little grunt.
There are so many tube choices, more than solid state, Push pull/ Single ended, Class A or A/B, tube choice, 300B monoblocks/ KT88/EL34/6550.
The obvious choice is a Conrad Johnson MV60 or SE, or Premier 11, to match the Pre and I may well go that way. Anyone any ideas? Particularly of course if you use living Voice speakers.I never buy new if I can and am looking to up spend up to $2000ish 2nd hand
I like most music, Blues, Singer Songwriters, classical and opera, so for the latter, I need something that can cope with a symphony orchestra. Thanks for any guidance
