3 channel amp for H/T

What is quite large? Are your speakers sounding like they are stressed?

jcfiver,
     
     The Monoprice Monolith 3 class AB amp, that mzkmxcv suggested, seems like a good option for you.  I believe this amp will provide a warm sound quality and a class D amp will provide a more neutral/accurate sound quality with a bit better bass.

     I'd suggest a good approach would be to determine which amp qualities are most important to you and let your list direct you to the amp that best meets your requirements.  Some examples of amp qualities are: price, overall sound quality, size, weight, electrical efficiency, operating temp, cooling fan yes/no, looks, wattage per channel minimum and maximum, warranty, free in-home trial period yes/no, input jack type rca/xlr or both, detachable power cord yes/no and any others you deem important.
      On my initial post, I mentioned Class D Audio as a good source for very good quality multi-ch class D amps at bargain prices.  Here are a couple multi-ch class D amp sources that I consider a moderate step up in performance, cosmetics and price:

Thank you all for the support.  I ended up going with a Proceed Amp-5 that I was able to pick up.  Very excited to add this to my setup.

Uh, I recommended the amp 3 for sale here. Did you find an amp 5? I’m sure that will be an improvement, but seriously, you need to consider upgrading your center speaker. If not the Paradigm I mentioned earlier, I think even this would bring a meaningful improvement to your sound...

Regardless, please let us know how it works out.
