One thing I did with my Teak Prism 3.0s was to use them as mains in my system, with 100watt monoblocks powering them. Obviously couldn't crnak them up , but easily got them up to "normal" listening levels. They sounded great, relatively speaking, and as I have said, friends through the Marble 9.0s were the connected speakers.
Wondering if you have exercised them in any way as stereo speakers with music, or compared them to other 3.0 series speakers?
Or compared them to the Marble or Ceramic 4.0s?
