I understand your love for the Studios, as I have them too.
I think that your RM9's were not really powerful enough for the Studios, which is why you felt something was lacking. (I started out with a Levinson 27 (100wpc) and when I went up to the Levinson 23 (200 wpc) things really opened up. (I am considering upgrading again, to get even more power, as the Revels really like lots of power.)
That being said, and coming from a fellow Studio fan, I can tell you that if you don't need the last word in bass, that the Avalon Eidolons will be a real step up. Used they are going for $10-$12K, depenind on condition, (and finish - some of the finishes are really drop dead gorgeous, especially if you are into fine woodwork!). The sound is bit more refined than the Studio, especially on the top end. The bass is close to, but not quite as deep as the Studio's depth. One caveat, is that the Eidolons are even more revealing than the Studios, so you will need topnotch electronics throughout your entire system. Also, the Eidolons are also as power hungry as the Revels. My friend's system (and I am basing all of my knowledge based on pretty intimate knowledge of the two speakers, btw), uses VTL MB450 monoblocks. (He used to use a Classe CA-401 (400 wpc) very successfullly, in case you prefer solid state.) In any case, you will need at least 200 wpc, and double that to really get the most out of them. He is currently trying them out with the Rowland 501s, but he has stated that the sound is not as good as the VTLs (or even the Classe, although it is close to the Classe.)
In looking at your current electronics, I feel they would do fine with the Eidolons. (But don't downgrade in order to raise cash to pay for the Eidolons!)
Well, Good Luck in your search!
