Trevor:
Sadly, you are over a year late. I had a loaner WOPL for a few weeks, summer of last year. I am using a Yamaha A/V amp in two-channel power amp mode, and it has good low-end power. It makes me happy, powering Vandersteen 2C speakers. I am trying to integrate a subwoofer, and that will take time. Twangfest may yet happen this fall - would you like me to keep you updated? It's an AK thing, lots of fun.
