Take the highly regarded Brystons as an example. Their pre-amps have an output impedence of 110 ohms, and their power amps an input impedence of 50k ohms. 100 ohms or so is pretty much a standard value for pre-amps, and matches the output of the TP.
Therefore this is a technical non-issue in your case. I hope that puts your mind at rest. -- bigfool1956 David Ayers Music is what counts, hifi just helps us enjoy it more ------------------------------------------------------------------------ bigfool1956's Profile: http://forums.slimdevices.com/member.php?userid=13782 View this thread: http://forums.slimdevices.com/showthread.php?t=46347 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
