Ultrapath bp Preamp


Anyone build/heard the ULTRAPATH bp (the "bp" stands for "battery powered) preamp?

Welborne has a forum over at AA and there has been some discussion on this product. Not a heck of a lot as it would appear to be relatively new to market. I'm struggling with trying to figure out the comparative "value" in replacing my Rogue 66 Magnum with either a Magnum 99 (used for about $1500) versus something like the Ultrapath "ulitmate version" kit for $1250...
I just finished the kit--and to say that I am well- pleased does not do justice to the sound quality of this excellent device.
KUDOS to Ron Welborne and Jack Eliano!
