McIntosh MC252 with Totem Mani2 / Sig's

Need some advice...

how well will the McIntosh MC252 drive my Totem Mani2 Sigs? i use 22' long runs of kimber 4tc, and wonder if the mc252 has enough juice. Would consider stepping up to the MC 402, but that is a lot of $, and I'm not sure i need 400 watts. let me know what you think!

also, can i bi-wire my mani2's buy hooking up two sets of speaker cable to one pair of speaker terminals on these mcintosh products? would that put too much stress on the amp?

thanks!
