Frankly, I couldn't find much difference. I think people are having mass hysteria when they talk about sounds. Presence of some low level noise is not perceptible unless you "meditate" on it. Psychoacoustically, most people are merely subjective when offering their opinions. I don't think a faint white noise would make a fuss.

There is no objective standard that can be used to convince someone that one system is " better" than the other due to the fact that ALL sound experienced in the brain is subjective . Yes we can use general consensus and electronic measurements to play the "Best " game but it eventually ends with , the best systems is the one YOU like the most .

Il suono dipende quasi esclusivamente dagli altoparlanti. Ho una coppia di AR M1 pilotate da un poccolo amplificatore in classe D. Forse è stato un caso, forse sono fortunato ma un suono così pulito e presente non lo avevo ancora provato. Saluti da Roma.

I’m listening through a/b headphones, a/b sounds warmer rounder but less impactful, d sounds boxy more solid but slightly sharper. D has that modern output which suits corporate and movies where a/b suits quiet listening and softer experiences

I’m old school. Got seriously into audio in the early 80s. So, naturally my auditory system is conditioned to the sonic characteristics of AB amplification. That having been said, I have heard some excellent sounding class D amps. Which may even fool me in a blind A-B test, forgive the deliberate pun. But currently my amplification is AB and I’ve no plans to make any changes. But, never say never.

I prefer the Class AB architecture. The LM3886 is an amazing amp IC. ST Microelectronics makes great class AB amplifiers chips too.

we need the punch of the D and the clean and warm sound of the AB. ABD? 😄

Biggest problem with class d amps is that they limit current so the music is not able to flow making it sound compressed

Is AB sound Louder ,Open and Fresh and the D is Low soundless and faded ?

Class AB is the winner in sound quality and fidelity aspect, class D is more compact, thus it need less power or has more efficiency but the sound is less realistic.

As far as sound, I listened through headphones and most of the time I couldn’t hear a difference. During the combined test, the left side had more bass. I listened to it twice to be sure, and then flipped the headphones around left to right just to ensure my own hearing wasn’t the issue. The bass moved to the right side when I flipped them. The only thing I can conclude is either the class D amp made the bass stronger, or the audio track was recorded with bass on the left instead of centered, which is not normally the case. Also the hiss test, I could definitely tell the class A/B amp was significantly quieter.

the moment you said that the gains were set 1dB different I stopped listening.

scam my mac already meet the requirement

is it supposed to be pronounced "gewey" or G U I ?

From my experience with amplifiers, the background noise can be reduced significantly by grounding the power supply, and keeping the input signal line as far away from the power supply line as possible, good grounding is essential so don't daisy chain the ground wires...

Amplifiers: The controversy over tubes vs solid state presists. When response, modulation distortion and transient intermodulation distortion are below certain levels (< 1%) there should be no audible difference. Speaker wires: It can be solid, stranded, copper, oxygen free copper, silver, etc.--or even "magic" wire--as long as the resistance is kept to be less than 5% of the speaker impedance. There is no listening difference as long as the wire is of adequate size. Bear in mind, a well-designed amplifier will not have a problem with any of these wires. CD players: In the 1980's, people spoke of experiencing "no air" and "aggression" while listening to digital recordings. Today we understand the principles which are fundamental to this phenomenon, we name it Jitter, we test it, calculate it and dress it with numbers, systemize it and describe it entirely. Jitter has always been and still is the worst enemy of the digital audio format. And today it is understood. Fact: Digital audio data is 'just' 0's and 1's. There may be many formats (.wav, .aif, CD-audio) but the information is still digital. There is no loss during format conversion, provided the formats don't utilize compression. Fact: Copying CD's (if they aren't damaged physically) is a lossless procedure. You can extract CD-audio with your computer and generate a file on your hard disk. Compare this file with the file created when you extract the same audio using a $30,000 player, the resulting two files are identical. The question which naturally arises out of this paradox is: why does the $30,000 player sound better? Before we answer that question, let us first understand that at the Digital Out of a $100 CD-player we have the same 1's and 0's as we do in the $30,000 player. The only difference is in the Jitter content. Jitter only means that the data (the 1's and the 0's) is not perfectly time-aligned, but is transmitted either slightly earlier or later than it should be in the ideal case. However, this time flaw is not as great as to cause a digital error (data fallout). Now if you know that, then you must ask: so why does one CD-transport cost much more than another? Ah, Jitter. The cheap ones shake and the expensive ones don't. Well, that's true. The entire audio business of CD transports and DACs is built on the totally backward setup of the CD player containing the Master Clock and the DAC being the Slave. This results in the entire palette of innovations to lessen Jitter, starting from air drives to expensive digital cable technologies with complex math to reduce line-induced Jitter, to very carefully filtered power supplies, to all sorts of very necessary things when you want to achieve the least possible Jitter. So we have the worst possible digital scenario bringing in the most possible amount of money, because it is extremely difficult to annihilate Jitter when the CD player is the Master Clock. If you're looking for quality, this is stupid, to say the least! The whole setup should be different. As is the standard case in any pro-audio studio, it is always the playing device, the DAC, which is the Master Clock. The clock is located right next to the converter chips. That way, no line induced Jitter can appear. This clock signal is then taken from the DAC device and is used as the clock input of the signal source device, say the computer, the DAT player, or the CD player. Yes, in that setup, the CD player is receiving a more jittered clock than the DAC is, but that doesn't matter, because the DAC is doing the audio playing. When the Jittered audio signal arrives at the DAC, it is quantized into place temporally and is then played, in perfect synch with the clock oscillator, which is right next to it. But oh! In that case, you can use a $100 CD-player with a very poor power supply, a digital cable made from your average household extension cord, and still get a better sound than you'd be getting if you spent $30,000 on the best transport and digital cable! Yes, ladies and gentlemen, this is the naked, uncensored, plain truth about CD players and DACs. Their Master/Slave relationship is BACKWARDS and their prices therefore HIGH. If you don't believe this, then all you need to do is record digitally your favorite tune from a $100 CD player into your computer (provided you have a soundcard and software that doesn't add yet more lies into the equation, which is often the case, so beware!) Then borrow the most expensive CD transport you can get your hands on and repeat the experiment. The resulting sound files aren't just similar, they are identical! But the $30,000 player sounds better! How do you get them to sound the same? You only need to slave the transports to a DAC in Digital Master Mode. That's it. Identical sound, guaranteed. The least possible Jitter. The least loss.

D is great for phone as a bluetooth

Class AB is the Best

Class D doesn't have that low-end finesse of class AB.

Tpa3116d2 is better, and tpa3255 is even better.

I don't think you are going to learn much from a couple of low end amps. The flagship Marantz PM-10 is class D and retails for $9K. Iron fist in a velvet glove.

I answered and said, "If I have found favor in thy sight, O Lord, show this also to thy servant: whether after death, as soon as every one of us yields up his soul, we shall be kept in rest until those times come when thou wilt renew the creation, or whether we shall be tormented at once?" 76 He answered me and said, "I will show you that also, but do not be associated with those who have shown scorn, nor number yourself among those who are tormented. 77 For you have a treasure of works laid up with the Most High; but it will not be shown to you until the last times. 78 Now, concerning death, the teaching is: When the decisive decree has gone forth from the Most High that a man shall die, as the spirit leaves the body to return again to him who gave it, first of all it adores the glory of the Most High. 79 And if it is one of those who have shown scorn and have not kept the way of the Most High, and who have despised his law, and who have hated those who fear the Most High -- 80 such spirits shall not enter into habitations, but shall immediately wander about in torments, ever grieving and sad, in seven ways. 81 The first way, because they have scorned the law of the Most High. 82 The second way, because they cannot now make a good repentance that they may live. 83 The third way, they shall see the reward laid up for those who have trusted the covenants of the Most High. 84 The fourth way, they shall consider the torment laid up for themselves in the last days. 85 The fifth way, they shall see how the habitations of the others are guarded by angels in profound quiet. 86 The sixth way, they shall see how some of them will pass over into torments. 87 The seventh way, which is worse than all the ways that have been mentioned, because they shall utterly waste away in confusion and be consumed with shame, and shall wither with fear at seeing the glory of the Most High before whom they sinned while they were alive, and before whom they are to be judged in the last times. 88 "Now this is the order of those who have kept the ways of the Most High, when they shall be separated from their mortal body. 89 During the time that they lived in it, they laboriously served the Most High, and withstood danger every hour, that they might keep the law of the Lawgiver perfectly. 90 Therefore this is the teaching concerning them: 91 First of all, they shall see with great joy the glory of him who receives them, for they shall have rest in seven orders. 92 The first order, because they have striven with great effort to overcome the evil thought which was formed with them, that it might not lead them astray from life into death. 93 The second order, because they see the perplexity in which the souls of the unrighteous wander, and the punishment that awaits them. 94 The third order, they see the witness which he who formed them bears concerning them, that while they were alive they kept the law which was given them in trust. 95 The fourth order, they understand the rest which they now enjoy, being gathered into their chambers and guarded by angels in profound quiet, and the glory which awaits them in the last days. 96 The fifth order, they rejoice that they have now escaped what is corruptible, and shall inherit what is to come; and besides they see the straits and toil from which they have been delivered, and the spacious liberty which they are to receive and enjoy in immortality. 97 The sixth order, when it is shown to them how their face is to shine like the sun, and how they are to be made like the light of the stars, being incorruptible from then on. 98 The seventh order, which is greater than all that have been mentioned, because they shall rejoice with boldness, and shall be confident without confusion, and shall be glad without fear, for they hasten to behold the face of him whom they served in life and from whom they are to receive their reward when glorified. 99 This is the order of the souls of the righteous, as henceforth is announced; and the aforesaid are the ways of torment which those who would not give heed shall suffer hereafter." 100 I answered and said, "Will time therefore be given to the souls, after they have been separated from the bodies, to see what you have described to me?" 101 He said to me, "They shall have freedom for seven days, so that during these seven days they may see the things of which you have been told, and afterwards they shall be gathered in their habitations." 102 I answered and said, "If I have found favor in thy sight, show further to me, thy servant, whether on the day of judgment the righteous will be able to intercede for the unrighteous or to entreat the Most High for them, 103 fathers for sons or sons for parents, brothers for brothers, relatives for their kinsmen, or friends for those who are most dear." 104 He answered me and said, "Since you have found favor in my sight, I will show you this also. The day of judgment is decisive and displays to all the seal of truth. Just as now a father does not send his son, or a son his father, or a master his servant, or a friend his dearest friend, to be ill or sleep or eat or be healed in his stead, 105 so no one shall ever pray for another on that day, neither shall any one lay a burden on another; for then every one shall bear his own righteousness and unrighteousness." .....2 Esdras 7:75 ////////////////

I always thought class D ampswere better for systems with subwoofers.

The 3 first choices are basically GARBAGE to a CLASS H amp. Class a, ab, d are all swell but made by MATTEL!! Where's the class H sound test!?

no it doesn't work ;(

does it have any virus? im scared to download it😭

how do i fix this? when i use framegui and after i use it i went to the video and its slowed down, how do i fix this?

Broo You Litreally deserves a like, I was editing a game montage and my clips were Soo laggy but you helped me. Thank a Lot men☺☺☺☺

Why so much noise on class D ? i don't remember any class D amplifier making this noise

ab sounds better , d is distorted

Class d is wins clears sound and smoth because the power filtering the sound

i get error "input is not a video"

Great video, but it would also be nice to see how many watts each used - and would be super easy to do. That's the only advantage of Class D in that point range - right? I think the AB clearly sounded better with much less noise.

Had difficulty with DAIN and Flowframe, FrameGUI works like a dream. Had a few slow, choppy 30fps videos that it interpolated brilliantly to 120fps without chopping. Although I suspect that 120fps provides no benefits to 60fps, but alas. DaGoose is da man!

any updates to this brother? mine looks very different

A test with a scope and THD measurement could be a good one

I like class H myself.. Class H provides the best of both worlds..

Will this be available for windows 11?

Is it a typical problem with Class D amp that smooth vocal can be distorted by a drum beat?

I've been mucking with electronics for decades, soldering for all of that. But I picked up some handy tips from this video. Really well done!

I have seen many videos and have changed many settings, but I still get lag. I was hoping this video would be it but unfortunately my videos lag due to overload. Not sure how to lower CPU usage but no youtuber seems to have what I need. I will have to sell my laptop and buy a desktop.

Volume match for a more accurate comparison!

Only voice coming not music

The test with left and right running on each amp sounded slightly out of phase even on my phone lol, class Ab for the win still overall

I had an idea, i know nothing about programming software and how it works tho. Would it be possible to port this FrameGUI to, let's say, the Microsoft Store and be able to download it on a Xbox? We would be able to use the powerful hardware that the xbox has. I don't have a powerful enough of a pc to do this things

Class AB win the test!

Thanks a lot, but its very very important from movie with another country BSO and another FPS, first adjust the audio speed and second the audio pitch

Old skool amp is da best
