Pick your poison...2-channel or multi?

This post is just to get a general ideas among audiophiles and audio enthusiasts; to see who really likes what. Here's the catch!

If you were restricted to a budget of $10,000, and wanted to assemble a system, from start to finish, which format would you choose, 2 channel or mulichannel?

I'll go first and say multichannel. I've has to opportunity to hear a multichannel setup done right and can't see myself going back to 2-channel. I'm even taking my system posting down and will repost it as a multichannel system.

So...pick your poison! Which one will it be, 2-channel or multichannel.
