Thanks to you and Paul R. for explaining the issues so clearly. I think Steve Nugent made it clear in the linked AA thread where the future lies: "Networked should be the primary goal of all audio companies IMO. The problems and impediments right now are: Systems are not open, and as a result: Devices are limited and proprietary Devices perform poorly by audiophile standards User interfaces are proprietary and usually not as good as iTunes We need to fix this." -- WKB ------------------------------------------------------------------------ WKB's Profile: http://forums.slimdevices.com/member.php?userid=20630 View this thread: http://forums.slimdevices.com/showthread.php?t=91692 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
