Concidering the Quads 89db sensitivity you should be fine with RWA int. I saw one up for sale with extra inputs at very good price. I am not familiar with 22Ls but heard their monitors. If they sound alike and your preferance is tone, inner detail, stark black backgrounds and musicality .......I would say yes. For around 1K used it is hard to beat.
Good luck
( I could help if in NY area )
