Got them home listening via X-Sabre > Ragnarok. These are fantastic. Much more soundstage presence than my Paradigms and more even. Paradigms (in my room) tend to have a suck out in the upper mids, though not unpleasant. The sound is more delicate and has more punch, definition is way up. Listening to some pretty intense electronica atm and it is handling it effortlessly. Bass extension is good, but I would suggest a sub for genres that rely on strong bass.
One nice thing about these vs the Paradigm is that with the stands included by Paradigm, the tweeter on the Studio 40 ends up about 2-3 inches above my head. The tweeter on the Amiga is about 1 inch above my ears.
Really impressed by these, can't wait to get them veneered. I might have to make another pair for myself!
