phono stage break in?

Larry, Granite makes a number of special purpose CDs, so make sure the one you have is either CD-101 or CD 101.1, which are the phono burn-in CDs.

I like the Cardas best, but I sure wish someone would make an LP that had a frequency sweep track(s) that filled the entire side so treating one's system every few weeks wouldn't be so labor intensive ;--) Anybody know of such a product?

The cover on this one saya "Model #CD-101.1 (with Bonus MC tracks)". All of the other tracks have been recorded at 4 mV output. Must be the one to get if you want to cover both MM and MC.

Neil, Larry, I get a bad ground loop when trying to use my BAT CDP connected to the phono inputs. I pulled out an old Marantz CD 63SE since it floats the ground. This fixed the ground loop, but it does seem to have a high noise floor. Sound right or is there possibly still something amiss? I know your not supposed to listen to the Granite CD, but I'm curious if that is also "seen" by the phono stage and if it is hindering the process.

How does this sound for a process. I'm going to let this CD run the MC track continuously when I'm not listening for the rest of the week. That should be me over the 200 hour point. Then play the Cardas a couple of times at the start of a session. I'm afraid to run the other 32 tracks through the MC input because of circuit overload.

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.....

Why can't you just record some broadband noise, reduce the level by some arbitrary amount, say 60dB, burn a CD of the now low level noise and then plug your phono preamp into the CD player. I've not tried this, but it should work.
