JAS Audio area demo-ed their complete variety of electronic, speakers and Zion isolation bearings, which my hifi buddy purchased a set, discovered it so.......
great, he went back to the show once more on the second day hoping to get yet another set, only to be disappointed, that all the Zion stock that they brought in for the show was sold out!
