I have a Vidar I used while my Sunfire was getting updated. Nice sounding, smooth, no noticible grain and great bass. It had plenty of power and control for a set of Revel F36s (huge room, 4500 cubic feet opening to other rooms). It ran out of power with my Magnapan 3.5s however, but that is to be expected, as most amps do. In a smaller room, it would have likely been adequate for the Maggies.
