Can a McIntosh MC7205 handle Polk Audio RTi A9’s?

I checked out bi-amping briefly. Tell me if I’m wrong.  I can biamp channel 1 & 2 and channels 3 & 4 to the RTi A9’s’ and channel 5 to the center RTi a6. I can use my MC-58 bridged to power the TSi 500s surrounds and the remaining 2 channels(30w) ea. To power 2 TSi 100’s or Monitor 40’s. It sounds too easy, where did I go wrong?

If I used my mac58 bridged to send 100w to the HF terminals and my Mac7205 for the LF terms on the RTi A9s and the surrounds. Would that work and would it give me more power for the Polk RTiA9s?

Your getting the idea.. See what sounds the best, and hopefully, not have to add a passive preamp (29-79.00). The less in the sound path the better, especially the mids and highs.

It would be better if you had bass control, over control of the highs. TOO much amp is better than not enough. BUT SQ is gonna be good with either amp. The leftover channel could run a passive sub, or center. I’m not a center speaker guy, so if needed a, passive bass bin.

Yes just watch out for that combined channel power it can be a lot more then you think because of the way the speakers are hooked up the amp might see a lower ohm, most Mac amps are not going to be affected by this in the least bit but your speakers will and if they are rated around 100w or less you could overdrive them at higher volume levels.
