@knighttodd,
The range of recommendations vary widely in how they sound. Have you heard many tube amps and can you describe what appeals to you? Both tube type and individual design matter. The difference between great OTL, and different pull pull tube type amps is like comparing a great sports car to a great SUV to a great sedan. All can be great, but which are you looking for?
Personally, I love the sound of Atma-Sphere OTLs and the M60s would be a great value and plenty for your speakers. Speedy, airy and spacious with beautiful natural tone.
BAT 6C33C designs are proven, evolved and convenient w/auto-biasing. Ballsy bottom end and a slightly darker tonal balance.
If you are inclined to stick with ARC, I've heard comments from a famous speaker designer about how much better the KT150 is vs. the KT120. Lots has been written on this topic and I'd suggest sticking w/the KT150-based designs if ARC is your cup of tea. IMHE, many ARC power amp owners end up dissatisfied after large investments and move sideways cost-wise to other options that make them happier. ARC built their rep on their preamps for good reason.
Quicksilver may not look the sexiest, but their owners satisfaction and their longstanding reliability are worth noting. Cheers,
Spencer
