I ran an Ayre V-5x for a while last year with my Andra IIs. I really liked the V-5x a lot with the Andras, but ultimately, I and a few others prefered a BAT VK-500 w/ the BATPAK as a more synergistic match for them.
From memory, the V-5x was more laid back and softer in the bass. Even though the Andras are a fairly easy load, they still like some strong current to drive them, and the BAT, with all that energy storage in the BATPAK drives them effortlessly and happily.
The V-1Xe, or the Ayre 300 watters should be a better match for the Andras than the V-5x was, so do give them a listen. But keep in mind that you can't go wrong the BAT and the Andras.
