Separate Amp for AV receiver

Are you in a position for that kinda upgrade

I think the ML should stay. Now theoretically you should match that center with a L + R Martin Logan

I have been using receivers as PrePro’s since the 80’s. I have a stack of OutlawAudio M200 mono’s that power my system, the “7” in my systems 7.1.4 description

i’ve owned a X4300 since it was released in 2016, extremely happy with its HT performance. I rreally like the Audyssey room correction, theres a real nice app that you can use to improve control over it via WiFi. I use (4) channels of the Denon for my (4) Atmos speakers.

Is it a Krell or DonSachs, of course not, nor does anyone claim anywhere it was, but for HT it does just fine. On the other hand if i ran the movie Transformers through my 2ch rig i would be very disappointed to say the least with the absence of 6000watts and (4) 15” sealed subs, That said, music and HT are two very different things, if Music is what you are looking for then a separate system may suit your needs.
While there are evil forces at work here on the forums with critical thinking and hard driving negative points of view, kinder advice is a much more neighborly jesture. Lets continue to look closer at some solutions for you friend :0)

    The real question is, is he unhappy with the music or the Hometheater experience?

    It is a Hometheater receiver which made me think he may be using it for a Hometheater, which most people here dont know diddly about :0)

Ok, lets take a look at ur HT speakers, what are you using ? Do you have subwoofer(s).
does the system lack slam ? If its HT ya gotta have slam, slam is where the money is Lol. Sounds like you have a nice 2ch system

Lets look a little closer at what its NOT doing for you, HT seems pretty straight forward, hook up all the speakers and bam its a HT, not always…..

You have quite an array of manufacturers there. The NHT’s show a 86db sensitivity which is not very efficient.
klipsch are usually in the hi 90’s which means they require more current than Klipsch.
the ML 50xt is rated at 94bd thats more sensitive requiring a little less juice.

i dont know what cgl.mtd means.

with this mismatch system im seeing why you are not happy. They all have a different signature. Power wise a nice 7ch 200watt per should do you well, its not going to sound bad, it just not gonna sound balanced.

if you research mastering suites for dolby atmos you will notice rooms with all the same speakers

I  see you are using two subs so list that as 1 as well

Another question can you illustrate the system, example: my system is a 7.1.4

7 mains and surrounds
4 Atmos 
1 subwoofer….i use 4 actually but since the get their signal from one output, i use the number 1, i think saying 4. Isn’t accurate 

And if you were actually prepared for that kind of a main speaker upgrade, they would def need their own outboard amp, like a 3ch cinenova high current able to control that trio.

Safe And Sound offers the 60xt mains refurbished not bad deal

What is your room layout, is it sealed off like a dedicated space or part of the living space like a living room, familyroom, some people believe the two are different Lol

With all this said we haven’t really address ur expectations as to SPL. I usually listen between 75-85db. If me and my son watch a real knock down bang up movie like Transformers or Tenet i’ll open up to 85-90db.
its not only important to match speaker timbre but establish what you want it to do sound wise. Are you interested in a ATMOS setup at all, the 4300 is very capable, i use mine as a quasi preamp processor. I use four amplifier channels for atmos and my Atmos speakers are little SVS bookshelf speakers, they blend pretty well
