Pure Class A amps above 100 Watts?

Sure, If you really want to rock find a pair of Parasound JC-1s. First 25 to 50 watts are class A then there is another 300 watts in reserve just in case you want to get Gary Clark Jr's volume right. These amps spent 15 years on Stereophile's recommended list. Longer than any single component in history. There are very few amps that can match the effortless power these amps provide and yet still have the airy lightness of a tube amp. And as a bonus they can drive anything. Only amps costing 3-4 times as much can compete. 

If you're willing to buy used a Krell KSA 300S is one of the best implementations of pure Class A topology. 300 watts @ 8 ohms, 1200 watts @ 2 ohms. You could buy one and have it restored/recapped and still have room in your budget.

I agree with 8th Note. If you can't build a sublime, balls to the wall system around a Krell KSA300 amp, there's something you're doing wrong. Save some money, fine tune with your preamp and build with your ears.

Any krell fbp amp will be better than the Ksa watt for watt.  The fbp use  regulated outputs

Gryphon Colosseum Stereo amp, 160w Class A. Smooth, powerful, and fast. 175lbs.

Your less than $10k requirement and greater than 100w Class A requirement are in conflict with each other.
