I've heard them. They sounded good. If they cost 25% of what they retail for, I'd still buy Pass or Rowland. To me, they look like aluminum pizza boxes.
Have you seen/heard the Spectron amp? I borrowed a friends & it was excellent on Wilson Watt/Puppy 5.1s! It costs around $3K. Looks like a real amp, too. John Dunlavy thinks highly of the Spectron, he knows good sound!
