Since I didn't have any responses to this query, I thought I would post an update.
I received my used pair of Craig Ostby's VRD monoblock amps last Monday and couldn't be happier. With the exception of absolute power, they are all I could ask for in an amplifier. They absolutely make my Montanas come to life. I am still toying with the idea of a custom pair with 4 output tubes per side, but lovin' every minute of the music with these little gems.
