Phono Stage Burn-in

I just got a new Phono Stage, a Sim Audio LP 5.3, and was wondering what I can do to accelerate burning it in. I know there's a CD you can buy that will work properly for Phono burn-in, but don't really want to spend the dough on something I will only use maybe a few times in my life. Anyone know if there are any downloadable tracks suitable for breaking in a phono stage with a CD, or an alternative method that doesn't involve running my TT, or allows me to run it on a loop, since I'll be working a lot the next few weeks and not able to break it in by listening.

Thanks!
