Anyone heard the Sony SCD-XA5400 mod + others

Warren Gregoire is doing mods to Sony SACD players in the S.F. Bay Area. Anyone heard the results of his work?
Haven't heard the 5400 but I did have a 9000 with a Modwright mod and have a VSE 9000 on its way to my house in a couple days. I could tell you how they compare if you're interested. By the way, I loved the Modwright. Those are probably the 2 biggies in mods. Bob
