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.

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?
You are probably looking at a totally different "watt" measurement. They play all sorts of tricks with THD, etc. Given that the MP amp is proabably a real solid 90 watts I would think it would definitley be an upgrade. Just looking at the transformer that thing has it should push some power.

As for the additonal power, I would not expect a night and day difference, but it is always better to have too much on tap for better control of your speakers and less risk of damaging them with distortion.

If you have old AVRs lying around, they have AMP for each channel. You can use the MultiChannel input/EXT channel input and try it. I came across this in YouTube while back.

Yes. This. This is the only sane answer unless your HT budget exceeds five figures.

I've been debating the 5 channel for some time now. Would supplement the Denon 3700 - take some strain off that and let it just power surrounds, Atmos. Somehow it's the one not on sale. Might just snag the 3 channel.

The 3700 does offer preamp mode, if I recall it doesn't support individual channels though.

Denon offers that with the 3800 and up.

Not all AVRs are same when it comes to per channel output. Mine puts out 120 per channel when all 7 speakers are connected. Of course, those AVRs are lot more expensive.

Here is what the website shows.

This is a new realm for me tho, so I'm not totally sure what to look for in the settings.

That said…I did order the 7 channel. I'm running a 5.2.4 system now Front speakers are Monolith T6 Towers, which are not very efficient (4 ohms, 87.8dB sensitivity). I see they can be bi-amped, another thing I'm not well-versed on. But potentially I could use 4 channels for the fronts, 1 for center, and 2 for my side surrounds, leaving the Denon to power just the 4 Atmos speakers, which I'm sure would be light work for it.

I am running a denon 3700 with 5.1.2. Would be curious on this would help my fronts with the 3x90 amp. Feels like they could use more power especially when watching with atmos enabled.

I'm with you....I honestly don't know. But I know its an itch I've wanted to scratch for some time now, and this deal is the motivation I needed. I went with the 7 just because $110 for 4 more channels seems like a no brainer. If I figure out a way to add rear surrounds to my room, I would need 2 channels of power anyway, so this allows for that down the line if needed.

I'm also planning to have my setup professionally calibrated with the MiniDSP, and I'd rather have the hardware in place before I do that, so I don't end up needing to do that over if I add an amp later.

Not a bad idea to just go 7. Most of my sound concerns come from the front. Rears and atmos are kind of whatever when it comes to powering them. Also don't forget whatever you preamp will allow the receiver to breath a bit more for those other channels. This is a no brainer at this price. Only if I didn't just order the Samsung S90C from the other thread haha. I do like monolith a lot. I have their subwoofer and it's fantastic for the price.

This makes me wish I got the AVR one step up from mine that included pre-outs. If I did, I would have spent more money at purchase, and I'd be spending even more now on one of these. So I guess it's good for my bank account that I didn't. But still got a little FOMO.

Good deal if you can use it.
