Anyone drive Verity Audio Parsifal Encores with tubes?

I currently drive these speakers with an Ayre VX-5 twenty amplifier and while the low end is very good, I know it can be better.  Also looking to add more transparency and body to the soundstage and images.  My preamp is the very capable Ayre K-1xe.  Perhaps a more powerful solid state amp would also give me some of the aforementioned qualities so I'm open to recommendations there as well.  Just curious if tube amplifiers could drive these speakers well too.  Budget under $10K preferably.
