I must concur with the Dunlavy SC1V's used (if you can find at $2500/pr), or the PSB Gold's if you're into Rock music! Actually the Golds can kick out the bass with more authority however, but not as refined and quick w/pinpont imaging as the Dunlavy's! However for $1000-$1200 used, the PSB's are a steal for Rock fans! A step up from the PSB's would be a used set of 3.3's from NHT! These have slightly less detail/rez than the Dunlavy's however, but as clear and solid through out!
Of the 3 I mentioned, with the Classe CAP150 you're using, the Dunlavy's are easiest to drive (higher sensetivity), followed by PSB's, then NHT 3.3's.
I've owned the Thiel 2.3's, and like em, but you'll klip the speakers too easy if you're into rock at louder levels with those weeker Classe's!(not as strong as others really)
You need much stronger amps with the Thiels, and there not really rock speakers like others.
For bookshelf monitors, I'd look into some Used Sonus Faber electa Amators for $2500 range used! These are strong sounding, and world class resolution and detail! Stay away from all those Dainty little speakers that are out there for Rock. Proac's, Sililoquies, spica's, etc, just don't cut hard hitting rock that well!...you'll be dissapointed if you even remotely head bang! Thiel 2.3 are OK ith massive power amps, but not Classe's older amps!!Dippolito's in floor standers work better for Rock usually, and are more dynamic often than conventional speakers, Anyway, good luck
