Try this from Tara Labs
Hagerman's inexpensive ($49) iRIAA inverse RIAA filter is a great tool for phono stage break - in. Put a CD on infinite repeat, feed it into the iRIAA, feed the iRIAA's output into your phono stage. Let it run for as long as you want.
Thanks for the responses, but I was more specifically know if there are any ways to break-in without spending money or spinning records, since I won't be able to play for a while and want to burn in while I'm away for work. I was looking more to see if anyone has made any tracks available for download that I could play off my server--see above.
So, let's try this again.
IIRC, Jim supplies the schematic for the iRIAA freely. You could cobble one together for the cost of parts (none of which are exotic in the least) for maybe $10-$15. Pretty? No, but it would get the job done. The beauty of the iRIAA is that you can select between -40 and -60dB which is useful for breaking in SUTs as well. Good, useful product.
