Other speakers in your price range, (used of course), that I would recommend would be:
The Avalon Eidolons, which are very transparent, and image and soundstage very well. (However, they are just slighty less than full range.) My friend used these for years, and he is mostly into classical music. They are fairly neutral and have a very nice tonal balance. They are very pleasing to the eye as well. Used, they run around $10K. You might even be able to find the Eidolon Diamonds for around $15K.
The EgglestonWorks Andra II speakers, (which I own by the way), are somewhat similar sounding to the Eidolons, in as that they too image and soundstage wonderfully. But they are a full range speaker. (Note: they might even have bit of a mid-bass hump - I can't tell if it was the speaker or my room, to be honest, but I think it worth mentioning. I have done a few minor room treatments, and the mid-bass hump seems to have disappeared almost entirely.) They look pretty good too, but IMHO, not quite as nice as the Eidolons. Used they run around $10K too.
Now, your amp will work for both of these speakers, but to be honest, they both deserve better, as both are very transparent, and will sound as good as the electronics in your system are. (I highly recommend Lamm amps, as that is what both my friend and myself used with both of these speakers.)
My two cents worth anyway.
Good Luck in your search!
