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.

They like big tube amps.  I will be with my buddy listening with a huge cary tube amp.  They sound tremendous.

The QS V4 monoblocks may be discontinued; at least that's what I read on their website.  They certainly are nice looking.

I will look into the Cary's.  Thanks!
I just spent the afternoon listening to Gregs Cary V12 with his Veritys.  They are a great match and sound unbelievably natural and clean.  
When I had mine I drove them primarily with Luxman Class A which was nice, but I auditioned them with an ARC Ref 110 and they sounded great.  I didn't want to get into big tube amps at the time but if you go down that path you will be rewarded. Those 110's seem to be a good deal now but I don't know how they compare to the above mentioned.  Have fun!
