I remember hearing those at the Audible Difference in Palo Alto,Ca. was
late 80's .. Used a Threshold Stasis Two along with the Threshold SL 10 preamp.. Linn Sondek set up w/Koetsu cartridge ..They played a Fresh Aire album... toccata maybe? it was very impressive.. very spacious with a heck of a wallop on the low end. I did not have a chance to hear anything else .
