Best amplifier for klipsch heresy 3 speakers.

The same question was posted on 7-1-12. Check past discussions.

I missed that old thread so I will add my 2 cents here. I own Heresy Is I guess you would call them, vintage 1976 before numbering. For reasons unknown, I found as do many others, that McIntosh power amps are synergistic with Klipsch speakers.
From the tenor of your post it doesn't sound like you have a budget in line with a new or even recently used Mac amp, so that would leave you with only the older Macs which is just fine, actually. I use one of there oldest and least expensive models the MC 2505. The best option might be a clean MC2105 which puts out over 100WPC, I know you don't need all that much juice for the Heresys, my amp is only a 50WPC piece. The tone of the amp is most important and since you have eliminated tubes, you have taken out a lot of amps with a warmer than standard tonality. Other choices might be- a used again low output class A amp. The other thing to consider is using earm cables, I like Cardas but they are expensive, Use good copper if Cardas is too much, leave out silver in any form.

You might consider a Plinius integrated amp. I have owned several and thought they were all good.

You did not mention a budget so I will suggest both new and used.

I have had very good results with Heressy's and Heresy II's with 80's/early 90's Denon PMA integrated amps(80w/ch to 100w/ch). Not what I would call "warm" but about as neutral as you can get with a very tiny lean toward "warm". These amps are fast and punchy with plenty of detail. Expect to pay in the range of $100.00 to $200.00 on the used market.

For new integrateds, any of the NAD BEE line will do the trick. New: C355BEE, C356BEE, C375BEE Used: C372

Cambridge Audio also has some nice affordable integrateds.
