This amplifier was just sent back from Power Modules where it was serviced and modified. It has neither the sonic character of it's original V1 origin or the current V2 which I also own. It's considerably brighter with a much wider and deeper soundstage with deeper bass. It's not as tube sounding as the V2. Cosmetically it's a 10, no marks anywhere to be found as the pictures show and since it just came back from Belles, internally I feel it's a 10 as well. I don't need both amplifiers and was going to sell whichever one I liked best which is the older one that was updated to V2 configuration.
