Norm,
I found a few extra Cirkulus cd disc enhancers in my stash. I'll send you one to try. I painted the top surface of one of mine with AVM. If I were to paint the inside with AVM it would increase the thickness and may not load properly with my up graded PS Audio transport. The disc wouldn't be a problem with top loads such as your Shanling. The Cirkulus sits over the entire top surface of the disc including the edges. Like a perfectly flat bottle cap. There should be no edge reflection.
