If you want to see how a bunch of the new receivers only put out ~30 watts when they go into a secret 'limp mode' with no indication that you are not getting the 135wpc you paid for......
Even if you forget and leave the internal amps on, the heatsink fans will never come on because they are not actually under load.

The 30wpc that you are currently getting from the receiver seems loud, but you are missing out on the dynamic peaks that can be 100w, even on moderate volume movie watching.
Community Reviews
The Monolith 7 channel amp is mainly a headroom and expansion piece for home theater setups, especially when an AVR is hitting low power limits or needs extra channels. It can run cool, add dynamics, and help with future Atmos or 7.2.4 upgrades, while some setups barely change because the receiver already has enough power. The main cautions are reported hum on some units, a two prong power cord, and occasional compatibility quirks. It fits best when the system truly needs external amplification.
Home theater owners adding channels for Atmos, because it can power extra speakers and free the AVR to run cooler.
Listeners with low-impedance speakers that dip hard, because the amp is described as stable enough to handle difficult loads and preserve dynamics.
Movie watchers who want more headroom at moderate-to-loud levels, because it can restore dynamic peaks that a receiver may compress.
Owners of older receivers that enter low-power protection, because this external amp is presented as a way around the 30-watt limitation.
Owners of receivers already driving their speakers comfortably, because several setups reported little audible change from adding it.
People expecting a silent rack, because the amp can produce a faint hum that may persist even after replacement.
Two-channel stereo listeners, because this seven-channel amp is overkill when only two channels are needed.
Buyers wanting a simple plug-and-play receiver replacement, because it is only an amplifier and still needs a preamp for volume and inputs.

What makes all this exponentially more complicated is the worth of these differences.
As I mentioned earlier Audyssey just keeps improving.
A1Evo is a perfect example.
People love to say Dirac is head and shoulders better than Audyssey(not really true), well not anymore.
Some even say A1Evo still isn't & technically true but free not worth it.
Think DLBC vs DL, that's the gap now.
TBH as great as Dirac(especially ART) is you should have the equipment(speakers) to make it worthwhile imo.
How well it works is heavily tied to the quality of your speakers, it's not a magic pill.
Again, it does not seem like you have any experience putting together a system for a mid sized room.
Although dialog may coast along at 85 decibels, peaks can easily hit 120+ decibels in a movie theater. If you want those peaks to be undistorted at home, you need clean power reserves.
You would hate my TIG welder, it has a 100 amp breaker all to itself.
Audiophiles pass away, and their wives and kids don't want any of that stuff. Martin Logan Prodigy, Revel Salons, Aragon amps.... all stuff that once was worth $$$$ is now just passed on 'to someone who would appreciate it'. Sometimes the kids will poke through the vinyl and take a few souvenirs, but they sure are not interested in hundreds of heavy records.
Peaks do not hit over 120dB. That is straight up wrong unless you are boosting past reference. 105dB is the peak for full range and 115 for LFE. But you said you don't listen that loud, so why does it matter? Also, as I have already mentioned, clipping up to 6dB can go
next time you are listening at your preferred level, go throw a power meter on one of your amps.
I'll move on now. It's a good deal. I just hope people actually think and learn how this stuff works and not just go off someone else's FUD and feels as to why they may need an amp.
More often than not that research is used to debate it as a universal answer & it's not.
In general terms I kinda agree with you.
A decent receiver provides enough power in normal use cases.
An external amp is pretty low on the totem pole on improving the sound imo.
Like "turnne", says the guy that uses "ASR or AVS" as their "audio truth" and fights with people that have actually used the products!!!! LOL
If you don't agree with their "truth", that clearly means you're "bad mouthing" their products!!! LOL
And even when many Klipsch speakers have a "nominal" 8 ohm rating, looking at the impedance plot and you see they drop to 3 or 4 ohms.
If you want to see how the industry has changed, look in the vintage room at your local shop and see that many speakers used to be 24 or 32 ohms.
Nowadays if a shop has a couple new pair of 10 or 16 ohm speakers you think to yourself 'This place has a huge selection! '.
....and the times they are a changin'....

I never said that, Superman said that.
A movie at 40% setting on my system is as loud as a commercial theater; and much cleaner.
Then constantly argues it's not the same as Dirac!
On that note, constantly claims Dirac is so great especially ART.
Then says DLBC is a VERY slight benefit(505 vs rz30)!
Constantly tells people if you're buying an AVR without ART that's bad(no influence
Yet for him it's not worth it and he could have had both(DLBC&ART) for $460 last BF!!!
I would be confused also! LOL
What was said under #2 again...!
"It's full of vendors who want to steer you one way or the other"!
Oh look, it's all based on reading "research"! LOL
The warning sign at my Imax theater for Oppenheimer said that peaks of 120db were to be expected, so I'd trust that sign over any kids on the internet telling me how loud a movie theater is.

hmmm "wrong" don't see that anywhere!
Oh yea forgot, you don't agree with what I "read" = "wrong"!!! LOL

Just because I post a deal, it does not mean that I 'personally' bought it (I've posted 100s of deals); or that it would currently satisfy me.
But, thousands of us (myself included) have bought receivers that will lock into 20w mode once exposed to a 4Ω load.
So, much better to have 130wpc @ 4Ω for the price of a dozen slabs of vinyl, than to limp along at 20wpc .
