For $5K, I'd be looking for a used set of Legacy Audio Signature SE. You mentioned, "Good sound for most music types." That is what I feel the big advantage of Legacy speakers is -- great "all around" speakers. You get the Air Motion ribbon tweeter, as well as 22Hz bass extension, they are easy to drive, work well in most rooms, great soundstage and imaging.
