Doody, I remember reading about this a while back and had a hard time wrapping my head around the speaker connection. I did find some appropriate cables (RCA - speaker) but never pulled the plug. So many ways to skin this cat, no?
Speaking of Chord .. I was very disappointed when they stopped supporting/developing their USB drivers, rendering USB input useless on the EX if you chose to keep the MAC OS current (like myself). Obviously, the DAC still works with Toslink and BNC, but not having USB really limits functionality. However, when deciding on which components I would use for my Summer System I became aware of some GREAT news which had previously escaped my attention. Jesus (Sonore) updated SonicOrbiter for the Rendu series to support many older Chord devices, mine included. USB functionality is fully restored via my microRendu! And it sounds wonderful. I can hardly express my delight with this turn of events.
