Do I need amp-to add to Denton 4300H, I to power Svs ultra towers?

Hello- need help, just bough SVS Ultra Towers, and Ultra center speakers, I moved my energy rc-lcr to side surrounds, and using energy rc-10 for rear surround, and PSB Dolby front atmos, 2 SVS pb2000 subs, I have a Denon x4300H , room 13x13, 9‘ tall ceiling, sit 5 feet from tv, and use the 9.2 for home theater only, but I love to play it very loud- volume is usually in the 70-80 range depending on the source, i just got it set up, watched pacific rim, and sounded great- but the receiver gets very hot- I just ordered a fan to put onto of receiver, but many have said the ultra towers need a extra power amp to power them to get the most from them.
1. Would you recommend I get a power amp?
2. If so, I would only power the front stage- 2 towers and center- need a 3 channel amp, not looking to spend over 1200, which amp would you recommend? ones I’ve seen in my price range is outlaw 5000x, emotive xpa 3, monolith 3 channel? is it worth the extra money to get the emotive or monolith ? They have more power but would I need it?
any help is appreciated, just tryI get to get the most out of my system for watching movies, thank you!!

Outlaw Audio Model 5000x. Use it to run your LCR (or LCR + a pair of surrounds) and let the AVR handle the rest.

The AVR-X4300H is rated at 125W/channel, 2 channels driven.

That suggests that for home theater use, you might not notice a diference if you add a 120W/channel amp like the Outlaw. (The Denon should run cooler, though.) That assumes (as the makers want us to assume) that an AVR is never driven to high levels on many channels simultaneously. (That's how they justify the relatively weak power supplies in many current AVRs.)

If you're power-mad, add the XPA-3 Gen 3 or the Monolith. There may be other worthy amps.

If the 4300 is getting too hot, but you're satisfied with the sound (no distortion), There are lower cost options:

You can turn on eco mode, increase the passive airflow around the receiver, or get an active cooler (ACInfinity). I have never used one of the Aircom coolers, but they seem to be well-regarded.

If I'm not mistaken, those SVS Prime towers are super sensitive, or at least sensitive enough where they should have more than enough power coming from the AVR. You really only need more power if you're trying to drive lower notes louder, from the mid-range on up, more power is just gonna fatigue you.
Mine are the svs ultra towers, not the prime, and from what I have read from other places -some have stated that the ultra towers need more power, but I was unsure if that is only for music? And some say amps are a waste if the current denon is not failing. Since I only plan to use them for home theater but I like it really loud when I watch movies - did not know if I would benefit from a amp added to run the front stage- and which amp to get if I did need one- ie is outlaw 5000x enough to boost my system or do I need the more powerful amp like the monoprice emotiva or and any suggestions for other amps under 1200 that would make my system w ultra towers better
as far as heat issue I did order a aircom cooler- get it tomorrow,
again thanks for any suggestions and direction to help me get the best out of my system to make for the best movie experience
I run two setups—one with separates and one with an AVR. I drive SVS Ultra towers and bookshelves with my Denon X8500H in a room twice your size. Are you noticing anything specific or do you feel others’ comments influencing you? It’s natural for the amp section to get hot i keep my Denon in an open rack. If you have it in a closed cabinet the heat will be exacerbated.

No specific issue, just noticed when I was researching to buy the ultra towers, people would note they need lots of power to get the best from them, 86db and my Denon has always gotten hot, because i have always pushed my old and now new system because I listen to movies really loud,watch Netflix in 4k all day, (so I was also worried since I pushed my old system hard, would the new speakers make it even hotter , the Denon it is in a cabinet but is open, and I just bought a aircom cooler -something I should of done 5 years ago, and plan to see how the system sounds -give it a few weeks
but was getting opinions if I should get an amp and which one, or is that a waste of $1K to add little to help me in my specific situation.
Audiophilia is an odd hobby. Some will claim that you need huge amounts of "headroom" (extra power margin) to get decent sound. Others will say that you have to use a tube amp, even if it maxes out at 25W/channel.

I'm not smart or experienced enough to argue either way.

I'm using an Emotiva XPA-3 Gen3 amp to drive my LCR, which are Hsu CCB-8s. I never experimented with just driving them off my AVR-X4300H.

Hello, thanks for the reply , do u like that amp or do u like the monprice monolith or save money get the outlaw 5000x but it is less watts or better 3 channel amp that is 1200 and under?
If you are curious to find out, you may be best served to snag a stereo amp with a 30 day in home return policy and see it for yourself in your own setup.

The proof in the pudding as they say will be there. I always recommend starting with two channel. Two channel is where you really see differences to judge from. Once you start adding multichannel to the mix it becomes much harder to perceive what’s actually going on.

I like the Emotiva. I got it during a period where the Monoprice Monolith amps were unavailable for a few months. Both were $1200 or less at the time (February 2018). The XPA-3 Gen3 runs cool. It's fortunate that it isn't much deeper, or it wouldn't fit well in my AV rack.

It's unfortunate that 3 channel amps tend to be much more expensive than stereo ones of similar specs.
