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.

Actually, I am getting the Otello’s from Paul and he has an AF ALS 10 he wants to sell me but it’s out of warranty.  I am skeptical about spending this kind of money without warranty.
Probably of no use to the OP, but for general interest: we were Verity dealers for twelve years and usually ran the Parsifals with an Air Tight ATM-2 or a pair of ATM-3. Pretty, pretty good!
I’m using a 28 watt Audio Note with the Otello’s and it drives them very well. I really like this combination.
I don’t think you need big power with these but please share your experiences. 
I've the Verity's driven with the big CAT tube amps at shows several times and was always impressed with the naturalness of the sound.  Very impressive, and was always one of my favorite rooms.

Best wishes,
