Sinosin: Sorry, Kr4 is right, go to the Stereophile link he posted. I saw it there not at the MAC website. It does not say a lot, but it gives a picture and short description.
I don't generally write lengthy articles for the website but, if you have any specific questions that I can answer about these components, ask. However, all I know is from a brief press presentation and the datakit I took home.
