I'm looking for a CD with some very low distortion sine waves,
preferably something along the lines of .01%, and preferably at a number
of different frequencies. I've borrowed a distortion analyzer and I'm
having trouble finding a clean enough source to really test out my
system. Any recomendations?

I'm looking for a CD with some very low distortion sine waves, preferably something along the lines of .01%, and preferably at a number of different frequencies. I've borrowed a distortion analyzer and I'm having trouble finding a clean enough source to really test out my system. Any recomendations? I don't own a sensitive distortion analyzer (and I've never checked with a 'scope - hmm) but I've gotten a lot of use out the Denon test disk. I can look up the disk id at home, but I think they only made one. It has sine wave tones ranging from 20 to 20k hz in relatively small steps (recorded at various levels), sweeps, low level linearity tests, noise tests, and all sorts of useful things. A very helpful CD. Larry -- Lawrence Hunter, PhD. National Library of Medicine Bldg. 38A, MS-54 Bethesda.

The Stereophile disk has them but only out to 1kHz. I need tones out to 20kHz. Mithat Konar
