Using two out of three channels--bad for the amp?

I'm putting together a small system for my parents. Source is a Sony SACD/CD player, speakers are Mirage Omni-60's, and the amp is a Jolida 1703 hybrid integrated. My question is... the Jolida is a three channel amp. Can I use only two of the channels, with nothing hooked up to the third channel tap, and be okay? Will this in any way harm the amp, or create some sort of dangerous electrical scenario? Would it be better for me to go inside the amp and disconnect the third channel, or leave the third tube out, or connect a dummy load to the third channel speaker tap?

On a side note... I went to my local Tweeter store to see what they had, and I found the Mirage Omni-60's on clearance for $299. I am really impressed with these speakers... Excellent build quality, and the omnipolar design really creates an expensive soundstage with very precise imaging. The speakers use titanium drivers, and the sound is a little thin right now, but I am hoping that break in will fill in the sound. For $300 though, I am very impressed. A very smooth, detailed speaker with good bass, and (as mentioned above) exemplary soundstage and imaging.

Thanks in advance for all of your help.
