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.
Years ago I drove the Parsifal Encore monitors with Atma-Sphere M60 MKII monoblocks and it was a wonderful combination. 

The Audia Flight integrated amps work well with the Otello's and is one of the amps he showed Verity with until Verity came out with their own electronics.  Paul doesn't sell or distribute them anymore so don't know where to look for them.  I bought mine from him right after I bought the Otello's.  

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.
