Hypex Ncore and Purifi's amplifiers are superior to almost any AB amplifier on the market. These are next level. Audio Science Review has measured them, as have others. Both amplifier brands I mentioned were the brainchild of the same designer. Class D doesn't break a sweat in its operating range and it's low distortion performance will still be just as good when pushed to the extremes of its rated power.

I believe this amp sounds much better than cheap class D amps out there but Class D never work for me.
I had Emotiva class D amp with Hypex Ncore but could not stay on my audio rack . Buckeys amp have much better spec 350 [email protected] ohms x 8 channels for just little over 2k . ( They are the pioneer of Hypex Ncore technology ).

I've been audiophile for quite sometime and numbers on spec sheets does not translate music in many cases.

Anybody have a decent experience with Monoprice support? I bought a turntable from them and a simple question turned real weird. I had used them for years without any problem.

I have a Monolith 7x that hums sometimes. Support gave me the run around. I would try my luck with Tonewinner or shell out more money for something else. Maybe Outlaw Audio.

Not really. Receivers are rated for two channels driven at 8 ohms, which made total sense back in the day of stereo. 99.9% of amps don't have a discrete power supply. They have a shared power supply. Adding new features is cheap, but upgrading a power supply is very expensive. That's why most manufacturers don't want to do it. Essentially, you're dividing down the power every time you add another speaker.

That's the purpose of an external amplifier. It's really not about max volume either, it's really about dynamic impulse response. A small power supply. It does not hove the reserves to quickly go from low to high. The receiver output now acts like a low pass filter and averages it. So you hear less detail.

An amp, on the other hand, is rated for each channel independently. So 8 channels times 100 means eight channels outputting 100 Watt simultaneously.

I'm not telling you to buy this product. Personally. I think it's overpriced. That is an electrical engineer's explanation for why someone would purchase a discrete amp.

If it's the amplifier (transformer) itself that's humming and not the speakers, it's probably DC in your AC lines. That caused a hum in my amplifier itself that would go louder and softer. The Emotiva CMX-2 fixed the problem and now the amp is completely silent.

"The receiver output now acts like a low pass filter and averages it. So you hear less detail."

That's all theoretical.
How many times are all channels of a multichannel signal outputting the same output proportionally, at max volume? Answer...never.
Typical 8ohm home audio speakers of typical efficiency don't need use/need as much wattage to reach max volume as people think. If so, you'd see people who routinely listen to their systems with volume maxed out.
A speaker with 88 db sensitivity only needs 1 watt to get that loud. 88 db is loud. Double the wattage for every 3 db increase in output.
Finally, people who are using external multichannel amps for home theaters are also using self powered subwoofers, relieving the main speakers of having to output bass, so they need even less power.

You don't know squat. You're obviously not an engineer. We add capacitor banks so that circuits can deal with quick impulses or high current demands. If the electronics cannot switch fast enough, then it will average the fast pulses. You will see a small dip, but it won't reach it's full amplitude. This is basic electronics. Power doubles every 6db. Decibels are logarithmic. You don't know the difference between power and voltage?
.

There's absolutely nothing theoretical about what I said. All this can be measured. That's why I like audioholics reviews and Erin's audio corner.

Notice we're not talking about one or two speakers. We're talking about five, seven, nine, eleven.

. You honestly don't know what you're talking about. Do you even have any technical background at all? I doubt it.

Lol.
Calm down.

Everything you said about the benefits of using a multichannel amp are theoretical in the CONTEXT of a typical residential home theater where you don't even know all the variables.

Let's take this one step at a time.

What part of the frequency range pulls more power from an amp? Treble? Midrange? Bass?

Is it more likely or not that someone using a separate multichannel amp or AVR (when using it in multichannel mode) is also going to be using self powered subwoofers, relieving the main speakers of a LOT of their power requirements they would otherwise be pulling from an AVR's amps? Yes or no?

Next, is the following true or not...an 88db efficient 8 ohm speaker only needs 16 watts to produce an uncomfortably loud 100db at 1 meter. True or not. How many watts from 2 meters away?

How many meters away is the typical listener in a typical residential room sitting from their speakers?

Can you gives us a few examples of a multichannel soundtracks that have max amplitude signals from all the speakers at once?

I have more, but could you please answer these questions first 👍🏼

Normally you got to have a dog or a pony to participate in the dog and pony show. The main drawback from a avr and it's amplifiers is the power supply.

Thanks for supplying true knowledge and wisdom. If I didn't understand the concept of amplifier banks and consistent rail voltages, I sure as hell wouldn't try to argue. Can't say that for everyone though.

I think we're all aware of the potential/theoretical benefits of an external amp. Where has anyone disputed that?

My point has consistently been those "benefits" won't apply to every situation. NO ONE can say that adding this amp to any/every home theater setup will result in an appreciable change.

Are you saying someone who has zero issues powering their home theater with their current AVR is guaranteed to see any benefit from getting an amp like this?
Please explain.

I did. Inconsistent rail voltages, the main flaw of most AVRs.

I love Monolith gears but slick deal seekers beware this is ClassD amps. That's why ads did not mention about class A/B like other post. Seller knew " ClassD " does not help to sell this amp. It's over price for the ClassD amp. They mention about distortion and clean sounds BS . This amp should be around half of the list price.

Anyone who think that I m wrong, let me know. If ClassD is better technology why not all high end audio amp still adapted yet. Why my 7 k 300B tube amp still not obsolete.

Class D has very weak damping ( very low cheap quality power supply design which they don't need expensive parts anyway) lead to my planner speakers sounding like radio.

Manufacturers push ClassD amp not because of sound quality but lower the cost.

ClassD amp has very dry and lifeless sounds in upper mid and high frequency. If you have a distortion free sound but no taste from music, why should I spend my time and money for music.

There are many amps choices if you spend 2 K.

I can tell these amps will dump on market sometime next year with big discounts. I doubt people still touch these ClassDam amps.
