I am guessing that the CD player had only a single output driver circuit for both connectors, and furthermore that the speaker amplifier had a relay muting circuit on its input that shorts the inputs when it is powered off. Both are questionable design choices, especially the relay muting. If required, that should be done after a buffer stage, or after some high input impedance, so that the source does not see a short.
Transporter doesn't have a problem because it has separate output drivers, and both have series resistors to provide short-circuit protection. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=47353 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
