Thus is probably not fair because I have not heard that model of VA. I am commenting because of some of the comments about Adcom. I have heard all of their pre's and consider most poor. However the GFP750 is a fine preamp, No other Adcom is in the same league. It is passive, it is active, it is single ended and it is balanced, doing all fairly well. I have met Frank and heard alot of his gear. For me, if I could get someone that I trust that clearly know them both and could tell me that the VA is better, I might go that way, if not, the Adcom is a safe bet and I'd run with that. Plus, not likely that you would lose on resale of the Adcom.
