Two Amplifiers Connected in Parallel?


Provided my preamp (receiver) can power two identical 2CH amplifiers, what are the advantages (if any) of connecting the two in parallel, one amp driving tweeters, the other driving mid/bass drivers?

Amplifier (Rega Maia) has a L/R link output in addition to L/R input. Preamp (Pioneer Elite VSX-32 receiver) has single L and R outputs. Speakers are Spendor 7/1.

George - Thanks again. Not sure that the Maia can be bridged to mono, but I will try to find out. The manual does not mention bridging as an option, but I will contact Rega directly to be sure.
