Amp for my Vienna Acoustic Haydns?

I'm in the market for a 2channel amp and could use some advice. My budget is $1-2K, new or used. My musical tastes vary, but for the most part are Rock (Garbage, Pearl Jam, Pumpkins) and Techno (house mainly). I'll handle the low frequencies with my M&K MX-150 sub. I've never heard a good tube setup. Based on what I've read here, a tube amp may not be the best setup for me considering my musical tastes, and it will also drive the front channels in my HT setup. I don't have a pre-amp yet, but may consider tubes there to "even out" the sound. The three amps I'm considering and plan to audition next weekend are McCormack's DNA 125 or 225(if I go this route, I would look for a used modded version), Bryston 4B-ST and McIntosh MC162 (is this SS?). Any advice on these three or others I should audition would be greatly appreciated.
I live in Atlanta, the city thinks it is a cosmopolitan city, but it sorely lacks a large variety of high-end audio dealers or brands.
