Can I use a multichannel amp to bi-amp my speakers

... I know that Gershman uses Nordost Red Dawn as interconnects and speaker cables and I'll probably go that route as well... I am leaning more towards the ModWright and will go Bi-WIred...

... was considering using preamp/s I have, with a vintage SimAudio Evolution W8 for sale here on Audiogon as a bi-wire (instead of bi-amp), or considering ModWright KWI200 to simplify ( and would bi-wire also). Was lead to believe that bi-amping gave better results regarding control and clarity: true?
