Hi Stephen. I will look through my Listener collection this evening. I just wanted to comment that the S100 is the finest speaker I have personally heard. I have owned several Thiels, magnepans, Sonus Cremona M's, Monitor Audios, and nothing provides the over satisfaction I get with my S100's. The real shocker was I bought them used two years ago for $1400! I use ARC Ref gear and upper level Nordost cabling, and they are never outclassed. They also sound great with smaller integrated amps. Frankly I wish I had discovered them many years ago. Would have saved me a lot of money! They are easy to drive, fairly efficient, detailed, and provide satisfaction on any type of music. I love 'em. I will the current importer would market the new models at a reasonable price... I would like a pair of the SA1's, but not at a much higher price than the rest of the world pays! With the current exchange rate, $2200 makes no sense.
