There's a much simpler approach, which I take with most of my gear. Just play it normally, and accept that it will take a while before it starts to sound its absolute best.
Amp burn-in..Best technique
I will soon be getting my new Mcintosh MC591's. I am curious,......does it matter how loud you play? If I run a CD on continuous repeat,...does it matter if I turn it way down? Or does that not offer enough resistance/load to drive to have a "break-in" effect. My wife would not be happy if I had my system playing at high levels all day.
