I rarely hear that other product beat AVA product in a comparision test. I am not saying that it'll never happen, but just rarely heard. Usaully it's the other way around, once people listened to AVA product and compared to their own, they threw theirs in the dumpster, then kicked themselves for paying too much for what they had before.
By the way, I don't have any FET Valve series eq. just some older AVA eq.
