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

I’m building my dream system with mostly used parts. I purchased the MC7205 to replace my McIntosh MC-58 amp for more power. I also ordered a pair of RTi A9. I’ve read in many reviews that said they need an amp with minimum 200w/ch. the Mac 7205 only puts out 120w/ch x 5.  If anyone is familiar with this amp or speakers, please I welcome any feedback. Thanks

You can bi-amp also, just have an extra rail left over. 120 for Bass might be a little light. Could also add a passive pre to adjust, the highs via RCA, XLR, IC. It's a Mac, those numbers are VERY conservative... 120 @ 8, for the lows, 120 @ 8 for the highs....Might work great...

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.
