Depends on which Integra 9.9 you are referencing. If the DTR 9.9 then no, you will not need amping as that is a receiver. If the DHC 9.9 then yes, you will need amping as that is a preamp/processor. In that case, you simply use either unbalanced RCA type connections or XLRs for balanced (no hum issues) from the preouts on the processor to the amp channels. If the amp in question has gain knobs for each channel, simply turn them all the way up.
If the DTR 9.9 receiver has preouts (I suspect it does), you can still run external amping if desired. The benefits of external amping are generally better dynamics (with larger capacitance reserves), headroom (greater output/higher volume without compression, distortion effects), better Bass control, etc., especially with speaker sets with more challenging specs. A 4 Ohm speaker with low sensitivity (say anything under 86dB) will benefit more than a higher sensitivity (90+dB, 8 Ohm) speaker. Audible improvement is usually on the margins. Larger spaces will usually benefit from external amping as well.
Klipsch are usually very easy to drive. If the listening space is not too large, you should be fine with the DTR 9.9.
