I love the sound of the system optique (with Small Green Computer linear power supply) - best digital I have ever had. But there is a small problem. About every hour or two it stops working when I change the music. My fix is to turn JRiver off, turn the LPS to the Optical Rendu off. Turn LPS back on and then restart JRiver. Not a big deal, but if this ever happens when some of my analog fanatic buddies are here I'll hear about it for the next year or so. Any idea for a solution?
