I've had the opportunity to hear most of the Focal Utopia speakers at one time or another, but I'm not 100% sure if I've heard the model you have. I know I have heard the Diablo, Stella, Grande, and one of the ones in the middle of the range.
My experience is fairly limited, but I've never left the store impressed when Aesthetix amplification was being used. Every time that I'm blown away it has always been Krell amplification being used.
What's crazy, I was blown away the last time I stopped at the store and the setup was a pair of Focal 807v speakers with the Krell S-300i and I came home more "unhappy" with my system that day that I had on previous trips with the Stella and Grande speakers hooked up to Asthetix gear.
My point is that you should hear any Asthetix gear (really any gear) before making the investment. The people at the store are obviously happy with the combination, but it's never been my cup of tea.
