Amp for Verity Parsifal

I am currently running my Verity Parsifal Encore's with a VAC Renaissance 70 III. I owned the amp prior to purchasing the speakers. Although the system sounds superb, I am wondering how much improvement I would get if I changed to an amp that would be a better match with the Verity's. If anything, the amp is a bit on the warmer and richer side of neutral(similar character of the speakers which may be a bit much). However, the amp is still very transparent with incredible realism, palpability, dimensionality, space and focus. The rest of my system consists of:
BAT 51SE
Basis Debut Gold
Graham 1.5T with new bearing cap
Clearaudio Accurate
Groove phono stage
Acoustic Zen silver interconnects
Oracle V4 speaker cable
Bybee speaker filters
Dedicated listening room - near field listening with Room treatment

I heard the Tenors at the Stereophile show with the Verity speakers and the source was an Audio Aero Capitol. Although there were limitations due to show conditions, the system had putity, transparency and immediacy that was beyond words. I also read that the amp is a magical match with my speakers. However, the amp is a bit pricey for my current situation.

Another amp I am considering is the Nagra VPA. My concern is limited power and possibly being too analytical. The Joule Electra rite of Passage looks interesting, although the model below is more in my price range.

You thoughts or first hand experiences would be greatly appreciated.

Thanks
