I will add the Rogue Audio Cronus Magnum integrated amp to the list. I had the II and had it upgrade to the III, not Dark. Huge improvement! Based on my experience it preforms as well as integrated amps costing triple. It supports Ultralinear if you need the 100W and a Triad mode with a warmer sound and about 65W. I seldom go past 15W so that headroom is only need when there is high dynamic range.
It is my amp for life.
