Two Amplifiers Connected in Parallel?

I tried it last year .My set up was Aerial acoustics 10T with Rogue Zeus 200W driving bass on both channels and Rogue M150's 150W monoblocks on mids/highs with Rogue Magnum 99 pre dual outputs.I REMOVED the bridging straps at the back of the Aerials.I used this set-up for about 2 months and then tried then Mark Levinson 27.5 connected on the same speakers and I prefer the sound this way better.I am planking in the future to get an active crossover like the Bryston 10B and try it as Atmasphere describes.I was told that the Aerials have a well designed crossover specific to the design so I am sceptical if an external crossover will achieve better results.Your milage may vary,but try and see for yourself.

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?

Biamping is a perennial topic, and it is usally asked by folks who know very little about it, except it 'sound' (inthier hhead at least) exciting and sophisticated. Biamping is neither of those things.
If you are going to BUY two amps, your are ALWAYS better off getting one better amp.
Ony if you happen to have two amps laying around, and want to play around, then yeah, try it.
And forst off you would divid a 'three way' speaker system by woofer on one, and the combined mid and treble on the other!
Treble portion of the output is miniscule!!
Say you are using 50 watts for the whole speaker, then 40+ of those watt is going to the bass, and 8 watts to the midrange, and less than 1 watt to the tweeter (on average).
Low frequencies use the majority of the power.
If you do a search about biamping, you can see that a few folks (who know what they are doing, get good results, the majority is almost as good to not as good as one better amp.
Save yourself the hassles and buy one good amp.

I am not familiar with the Spendors,so assuming that they are bi-wire capable,that is they provide TWO inputs at the back ,then remove the bridging straps.Your connection seems wright.
If you want go to youtube and search for "virtualdynamics" "QnA bi-amping" there you can find a 10 minute tutorial from Rick who explains it further.

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.
