I see that you list Klipsch Heresy IIs, they would probably be a good match especially if you rebuild the crossovers with new caps. I recently rebuilt a set of Klipsch Forte's with Auricaps and am stunned by the sound of them matched with a pair of Dyna Mk II amps converted to MK IIIs and using the DIY Tube board with 5751s and 12BH7s.
When rebuilding the crossovers, you can get the schematic from the Klipsch website, and it is not usually necessary (or easy) to replace the large cap in the Bass section. Replacing the 3 or so High Freq caps with Auricaps makes a huge improvement, Auricaps can be purchased thru Michael Percy Audio (website) or other locations. You may also consider replacing the stock resistor with a Mills Non Inductive wire-wound also availbe from Michael Percy. My Forte rebuild cost about $35 per speakers and the solder slinging to change them took about 30-40 minutes each. Be sure to secure the new caps woth some sort of adhesive (silicon sealer, etc)

Another recommended speaker would be the Dynaco A35. Many say it is the best sounding Dynaco speaker, having owned a pair and having compared them to the A25, I would have to agree. Again with any of the Dynaco speakers, rebuilding the crossover with Auricaps. Some additional info on the Dynaco speakers is available at:

Hope this helps.
