Finally got around to installing my new PSB deck speakers (report in the speaker section) and used my vintage Denon DRA-755 Receiver to drive them so it was finally time to buy a new amp. With the release of the A2 and adding the auto on feature (I drive it with Airport Express) it was perfect timing to buy. Speakers are Mission 770s with MK powered sub. Still sounded good with the old Denon, but the A2 really opens of the mid and high end on these speakers. More that twice as much power makes a noticeable difference in dynamic range. With the wife still working from home I haven't had a chance to really "test" everything but so far liking what I'm hearing. Fit and finish is excellent. Shipping package is solid with no delivery issues. Overall looks like a quality product.
