Hi,
Great question. I still have them, however, they are in the midst of some tweeks. The speakers sounded better with tubes than solid state so I needed to try some new crossovers. I tried two different sets, but they still didn't sound as good with SS as tubes. The speakers' response is being measured and new crossovers will be put together soon. I'll make sure to bring them to the Criterion or Dolcetto ribbon speaker evaluation in the late Summer/early Fall and share my thoughts. Quitie honestly, I wanted to complete this sooner, but got tied up with my new job and all of the travel I've been doing. Very sorry...
Jack
PS- if you are looking for speakers to use with a tube amp, I STRONGLY suggest looking at Louis' Omega line. They are unbelievable speakers.
