Loudspeakers played LOUD

Snook2, I have dunlavy V's too, and VERY happy with them. There is always VI's that probably could play louder, but , Mr Dunlavy's own admission( I talked to him on phone few times), not necessarily more accurate (ACTUALLY LESS) than the V'S.
Otheres could be The big Montana;s , Pipedreames, and bigger Avalons and Grand Utopia's. Other than the Avalon's( forgot the model name) have not heard rest.

Now my question: What you fellow Dunlavys think of my idea: I have one Classe CA-400 driving the V's, with 800w/channel max power ( at 4ohms). Would I gain a whole lot if I add another CA-400 resulting in 2400 w/channel? I have one available at audiogon at a great price. Appreciate your reply

P1s1, thx for your input. You addressed the loudness point of perspective, which makes sense, rather not to have another CA-400, since in my room , at near field listening I rarely listened to beyond 100 db(clean sounding at that), where sound stage depth and imaging suffers. Although some of the demage is caused , no doubt, by my average size L -shaped room,adding Comfortable head room by going monoblocks and tripling of maxpower, is there any gain to be had in soundstage and imaging ? Sorry snook2 to use your forum to solve my problem. This is the last question, I promise.

Let me add to Snook2 comments : accurate means both 'tonal' and phase correct. If acaustic bass or drum is located at certain location (left to right and depth), V's reproduce it accurately. In other words very flat to 20hz in room.
