Dan..I purchased a used pair of the these a couple months back and they are by far the best from what I've owned or heard. They are tube amps cabable of driving any speaker (I use Sonus Faber Extremas, not the easiest) and have a firm, powerful bass which will make you forget about solid state, and very neutral mids and sweet highs..these never sound harsh yet never overly (but somewhat) warm. Even my friends who prefer solid state are impressed by these..they are really are hard to fault..almost forgot to mention that they always sound effortless..time to warm em up.
