phono stage break in?

If it was me, I will get this http://www.hagtech.com/iriaa.html instead of a CD. In the long run, this will prove to be a valuable tool. I am using one and it works flawlessly.

Read the description, it is self explanatory. You can use your tuner, cd player, ipod, etc.

KAB makes a RIAA pre-emphasis box that you can use with any line source. It provides a MM level (which you should also be able to use as an MC input carefully, use the highest possible loading)
FM interstation noise from a tuner with its "white" characteristic (equal, random power distribution across the band) should make for an extremely effective break in tool.
I use it. I am in no way affiliated with KAB

I agree with Nick! Why is it that I am seeing the importance of the pre-emphasis/de-emphasis feature as well as proper attenuation not to overload the phono preamp in using this devices plus a wider selection of source that can be use instead of a cd? Maybe because it mimicks a real TT cartridge signal? Maybe.....
