I want to get hold of a free burn-in CD for my new amp. Does anyone know
of a public domain download that can be
copied to CD and played?
I am also looking for a similar download file with tones
of different pitch but the same volume to compare left
and right speakers.
Yes, I could buy something over the web from the
Audiophile / Stereophile website but I want it today
still.

Note: business opportunity for those who ply the snake oil trade.
