converting stereo power amps to mono


I will shortly have one superfluous Sonance 260 from one system and no amp for my Chapmans in a separate systwm. Am I better off dropping the Sonance and looking for a $3-500 dollar power amp or picking up another 260 and figuring out how to convert them to mono power sources?

Not all amps can be "bridged" and it does not always have desirable results even if it can be done.
I guess my real question is the effect of splitting the output from my pre-amp so that the same information is delivered to the left and right sides of each power amp. Your thoughts?

Thanks for replying.

Cheers,
Jon
