You could short the 100R output resistors to get more power. I'm not sure how much the op-amps can cleanly drive - I only ever tested them with loads as low as 600R. My guess is that headphones driven directly should sound great, at low power levels.
Rocket - it would definitely be considered an "active" output, although I wouldn't call it a preamp. A "passive" preamp would be a simply a potentiometer and some mechanical switches (or perhaps relays) to choose an input. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=28236 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
