Man, your description really points to Triangle speakers. Grinnell is right on the money IMO. The Titus and Stella are in your price range, new with warranty, and your 30W amp will love them. The Cometes have a lot more bass but are also around $500 and are much larger.
I have had Monitor Audios, Energies, Paradigms, Epos, Elacs, and Triangles and in general the Triangles are the best of them all IMO. They have a very vibrant character and have image separation and definition like no other in this price range, and yet they are very coherent and melodic. Awesome speakers that will really make Radiohead sing (except for track 2 on Hail to the Thief for which you need a speaker with exceptional bass capability).
Totem Rainmakers are enjoyable but don't have enough treble accuracy for the level of imaging the Triangles are capable of. The only other speakers I have heard that come close are the ERA D4 speakers from Signal Path, which you should also consider but they are not nearly as efficient as the Triangles and I don't think they look nearly as cool either.
