Posted this to the Zkit60 forum, but I think most are missing it:
The Zkit60 is the baby brother of the Vision Set 400 now being sold by Audio by Van Alstine. Differences are that the Zkit60 is 60wpc, not 225, and the Zkit60 is not recommended for 2 ohm loads.
Audiophilia's review of the Vision Set 400 can be found here:

Bottom line: The Vision Set 400 so impressed the reviewer that he bought it with his own money and is making it part of his reference system.
