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.

Thanks everyone for the replies. Comments so far leave me on the fence regarding this. I don't have much experience in this sort of thing but intuitively, somewhat makes sense.

If I do try this, here is will do:

Equipment: Pioneer Elite VSX-32 Preamp/Receiver, Two Rega Maia amps, R & L Spendor SP7/1 speakers

Single line L and R outputs from the preamp and connect to L and R inputs on amp1. Use amp1 L and R link outputs and connect to amp2 L and R inputs. This is the parallel connection.

Amp1 R speaker outputs to R speaker tweeter, amp1 L speaker outputs to L speaker tweeter.

Amp2 R speaker outputs to R speaker mid/bass, amp2 L speaker outputs to L speaker mid/bass.

Make sense?
Thanks again for all of the replies.

Elizabeth, I do fall into this group: "usally asked by folks who know very little about it, except it 'sound' (inthier hhead at least) exciting and sophisticated"

Yioryos -- Thanks for the virtualdynamics video on youtube. Most of the discussion involves vertical bi-amping but after viewing I'm not sure why vertical or horizontal bi-amping really should ever be considered. It seems that monoblock amps are the only consideration if using two amps in a 2CH set-up.

I've decided against the horizontal bi-amp idea.
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.
