You can do that, but at the expense of giving up the inverse feedback loop that is normally part of an amplifier to compensate varying load, component drift, and supply voltage issues, because you obviously cannot feed the analog output back into the digital input. Without the feedback, however, you have to do some forward compensation in the DSP stage, which means you need to know the speaker characteristics in advance. I don't know the current Sonos product line, but as far as I can see, such a design is only feasible for units with built-in speakers. -- usch ------------------------------------------------------------------------ usch's Profile: http://forums.slimdevices.com/member.php?userid=33389 View this thread: http://forums.slimdevices.com/showthread.php?t=73069 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
