No, it would not use digital attenuation. That's the point of the experiment. Your just using the analog amp of the receiver. And the DAC/Anolog preamp of the SB3. Some receivers WILL process the 5.1/7.1 inputs some will not. Some will still apply room correction in digital domain and therefore do ADC. No receiver will do anything past the jumpers though (if you have them). That is a pure analog at that point. Even volume should be bypassed. -- mswlogo ------------------------------------------------------------------------ mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=35642 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
