Assuming the H/K receiver has premp outputs, it seems that a pair of audio interconects with RCA plugs on both ends would be in order. If not, you've got a problem there...
Lkewise, it seems that little amp has 5 way bi nding posts for speaker outputs. In such case, virtully any speaker cables will work between that and the speaker.
I hope that amp has enough power to meet your needs...
