phono stage break in?

The hagtech board was recommended to me as well. I do think that may be the best way to do this. However, as with the CDs and the hagtech circuit board, once your state is broken in these are not going to be used much at all. I suppose one could purchase one of these and then sell it when done with it. The Cardas record that Neil mentions is really worth keeping around because you will use it.

I would echo Nsgarch's post. I also have the Granite break-in CD, but was not aware of the differences between the Granite and the Purist Audio CD's until Neil's post.

I would suggest owning both the Granite CD as well as the Cardas Frequency Sweep LP.
.
The Cardas LP is a great tool to own for the long run and well worth the $ 25.00 - 30.00.

The Cardas LP has been great to run in my system every 3 - 4 weeks (the frequency sweep side, not the burn in side, the burn in side is fantastic for cartridge break-in). I always notice a significant improvement in the Sonics of my system after playing through the Frequency sweep tracks. The results may vary based on your system and what cartridge you use.

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
