Ross, I run a set of JBL ND310's and the amp has no issues what so ever making them "Sing" I believe this will also be the case for the Klipsch Forte's If your worried about it just step up to the Harman Kardon HK 3490 120 Watt Stereo Receiver. A few extra watts, same quality. I love my receiver. I replaced a Carver CT-17 & power amp. Happy I did.
