Have you heard the anniversary? It seems somewhat extravagant but if Jim Aud's claims are accurate then it will be an extraordinary performer.
I have not heard the Purist Anniversary. I have, however, heard the Aqueous Anniversary. I own a pair of Aqueous Anniversary and Venustas. Good stuff. I believe Boa2 has posted a comparison between the two.
What's $8000? C'mon, drop a dime.
