Gee, I heard pretty much the same thing :-) The 688 comes from Olin 688 alloy brass that the custom connectors are made from....The HSR-I has been around for almost eight years and the HSR-A over six years and the Gen II versions of each for a couple years....Sonically the cord sounds like a Gen II HSR-A that is more forgiving in the upper midrange....These will be available in late October and updates will also be available for the HSR series at that time as well....Formal introduction will be at the CES in January...
