Wilson Alexandria x2 series 2 vs XLF vx Alexx?

The OP of this thread :
My Long List of Amplifiers and My Personal Review of Each! | Audiogon Discussion Forum
has been on a long journey through some very high-end gear.  He currently has the Alexx and I know he's had other Wilson speakers, so you might want to check out the thread and maybe ask him,

I dont think Jay had x2 s2 or XLF.

Paragon has the Alexx and the Alexandria X2 both. I spoke to them about both and decided to order the Alexx. More musical they said.
