Some receiver's choices that will do good to your Klipschs.
Hi Drake & Welcome to the club.
About an Onkyo tX-SR805 ($600), if you can find one.
Or an Onkyo TX-SR876 for $950. (Accessories 4 less.) * More $, but worth it.

(Was $875 at one time.)
Or a Marantz SR8001 for $700. (Great receiver for a great price.)
Or these with a bit les than 130 watts per channel, but still very good in their power delivery; the SR6003 for $625.
The SR 7001 is only $500.
And the SR6001 is at a low $350.
Or an Onkyo TX-SR875 for $750. (Good deal plus power.)
There is always the Pioneer Elite SC-07 for $899. (Not too shabby for the price.)
Or the Elite SC-05 for $689. -> (But I still will go with an Onkyo or Marantz.)
So, here you go, some of the very best, if not the best at prices between roughly $300 to $900.
-> Just check all of these above at: Accessories4less and 6th Avenue (at 6th avenue, you name your price). Other good places for great deals: Audiogon and Videogon.
* Too bad for the XPA-2.

(One of my very favorite amp; don't know what happened here!)
