Yes it should alter as it's a feedback mechanism - this is what "async" usb is all about. The dac tells the transport how fast to go and the transport changes its rate as told. The critical thing is that the crystals in dac and player will be at slightly different frequencies. There is a buffer in the dac, so all that is required is that the dac tells the transport to slow down or speed up to keep the buffer half full - this is what is happening with the different rates you see. The fact it is changing means it is working in async mode. It's interesting how different dac manufacturers have implemented these changes differently - my audiolab for instance alters the frequency by 100Hz or more between the go faster and go slower message. Your dac appears do adjust on a more fine grain manner. However the bit that matters is that it is updating. -- Triode ------------------------------------------------------------------------ Triode's Profile: http://forums.slimdevices.com/member.php?userid=17 View this thread: http://forums.slimdevices.com/showthread.php?t=93310 _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
