Anybody compare Mystere ia21 to ARC VSi60?

Thinking of getting a tube integrated. These two both have received excellent reviews. I don't have the opportunity to listen to both of these in a controlled setting. BTW, my speakers are Acoustic Zen Adagio.
Ayon Spirit III ought to be on the list too.
I have the Mystere and like it alot. I had the Rogue Cronus Magnum before this.
I haven't heard Mystere, but ARC VSi60 is the the most musical and transparent amps I've ever had in my system.
