You're not getting anywhere near the rated specs with 7-9 channels driven on most modern AVRs.
Unfortunately there are too many IFs for a universal answer.
This quickly becomes a big rabbit hole because of that.

In very basic terms is your receiver " putting out" efficient enough power to drive your speakers to your preferred listening levels.

I would point out if you're looking to upgrade the sound you hear, you should look at your speakers, their placements & room environment 1st.
That would have a much bigger difference in SQ over an external amp imo.
Is there going to me much of a difference compared to what a modern AVR can put out? Most AVR's can output anywhere from 75W - 125W channel and yeah when you're driving more then two speakers it will be on the lower side, but having a dedicated 90W per channel in an external amp doesn't seem like much of an upgrade. If it was like 150W per channel then it would seem like more of an upgrade. But please correct me if I am wrong.

Great price on the 7 channel. I don't "need" it but it will take a load off the receiver.

I bought the M2100X 2x90 amp! If you need to supplement your mains, or you're doing a 2 channel system, this is a good option! Check out this review. It only reviews the 2, 3 and 5 channels versions. Remove the spaces (obvious) https:/ /www.youtube.com/watch?v=tpMybj9p_Ec

I have the same question. I have a 5.2.4 system powered by a Yamaha A2050 receiver that has 140W per channel when 2 driven, but I think that drops to like 55W per channel when 7 driven continuously (probably even less when driving all 9 speakers). They are pushing Polk in-walls that are 91db and can handle 200W in the front. I've always been happy with the sound, but I do wonder if I'm missing something that dedicated amps at even 90W per channel would provide for the front speakers. Or should I not waste my time with this Monoprice option?

As for the 2nd half, there's no cheap AVR with either Dirac or Anthem RC with pre-outs for less than $400 right?

I love music, is m2100x a good option? I'm thinking about replacing the AIYIMA A07
