I have Salons, as does a close friend of mine, so I think our experiences will be valuable with regard to the very similar Studios.
The Power 3's do sound excellent with Salons. My friend ran this combo for a little over a year. Kal Rubinson of Stereophile runs Power 3's with Studios as his reference.
I also ran Rowland Model 6 monoblocks on my Salons for a brief period of time -- excellent synergy and very refined, natural sound with excellent dynamics.
Both the Power 3's and Rowland 6's are $3,500-$4,000 used, and both were over $10k when new. Power 3's produce a lot of heat. Rowland Model 6's are compact and, by hi-fi gear standards, very attractive.
The Salons and Studios require an amp that can produce current, so my advice is to stay solid-state.
Good luck
