Let me (us) know what you think of the Sheffield setup disc, when it arrives from Rollo. I will likely want to try it for my set up as well after I move next week.
I do plan to post some comments on the Ayre system enhancement CD that I got from a friend called, "Irrational But Efficacious". Done in collaboration with Cardas. Very effective for equipment break-in and "demagnetizing" your system for better sound.
