After reviewing your choices and the follow up posts, I would stick to your guns - especially your preference to the Edge, Gamut and Lamm amps. Do consider Kieth Herron's mono block amps - they are dynamic and musical.
I would not be overly concerned with the SS vs tube reliability issue. The tube hassle is every two to three years and the trade off may be significant to your ears.
