Alon I and II (used for the IIs to stay in your price range) sound excellent with Acurus electronics, and I'd recommend you audition them. I took three of my non-audiophile but music loving friends to my dealer to hear various combinations of electronics and speakers and they all wound up with the Acurus DIA and Alon IIs. They sound good with all types of music. Good luck!
What to do? What to do?
I need to acquire speakers for my system (Acurus ACD-11, Aragon D2a2,Aragon 18k, kimber 4pr and pbj). I currently own a pair of BW 620 (free for helping my neighbor move). They've never wowed me with my rock music (which is about 50% of my collection) but I enjoyed listening to chamber and jazz on them. I'm a grad student and this will be my first real speaker purchase, so budget is an issue. What direction should I take in my search for some accurate speakers.
