I loved the Aesthetix Rhea. I ended up buying the Conrad Johnson EV1 though, and it's marvelous, especially at its price point. I haven't heard the Boulder yet, but from what people have told me it's the most amazing piece of gear on the planet. The local Boulder dealer, who also carries Aesthetix and BAT, told me point blank "Do yourself a favor and don't listen to the Boulder. It's THAT good."
