What's causing the sound difference between two class D amps.

Brother it's not so hard to connect + to + and - to - it's easy ... As you said I flipped polarities. I done that but still the same output appeared , the problem lies in the board itself it has some issues... Listen to this this is before I returned the product ...

Would you please clarify. Flipped polarity of one channel and you still got the same result? (You are getting the same "half baked bass" at the listening position?) Something seriously weird is going on here. Flipping polarity of one channel has to produce very audible differences when compared to before flipping.

Wait, sorry, I meant No

How about ...Perhaps

ChatGPT once advised me to use the underside of my desk as the safety containment for 120V AC terminals on a DC power supply and distribution block - it probably would not have started a fire or killed me, as long as I didn't touch it. Probably.

Lol chatgpt is intelligent

Bc the board is faulty dude even I was shocked ... The seller told Me maybe it's faulty send it back and I did

Well I'm here to inform you that I flipped everything again before returning the product to the seller and it was bassy but the sound quality was not warm and likeable... I guess I love the distortion in ab class amps lol , that loveable smooth creamy bass is more enjoyable to me rather than a clean heavy bass and clean mids with no warmth

When used within their design parameters, good Class AB amplifiers do NOT have audible distortion. Good Class D amplifiers do NOT have audible distortion. That's it.

It's quite possible you used to own a broken or rubbish Class AB amplifier and liked its distortion more than this broken and rubbish Class D amplifier you are discussing in this thread.

hey guys i had a question .... does all D class amps sound shallow in mids? my speakers and subwoofer are fine .... i tried xh-m139 and it made me wanna go back to ab class amps since it sounds unnatural and robotic like a cold soulless sound i guess ... the ab class amps sound much more natural and warmer .. is there a way to make the output sound more warm with D class amps like xh-m139 ؟ i tried using it but TBH its kinda harsh to my ears .. esp in games like valorant and marvel rivals the sound diff is much more noticeable .. like the ab class is wide and warm the D class is like cold shallow and kinda harsh to hear . what you guys suggest ? is there a way to make them more like ab class amps ? like if i buy this module (((((XY-s100h ))))it would sound like xh-m139 or its better and warmer ? can it be modified to be warmer ?

Well I changed some stuff like changing polarity of every speaker even the subwoofer
And this time the sound was alright but I guess it's just not matching my taste... It's clean and bass is heavy hitting and all but it sounds cold ! I like warm and wide sound ... therefore imma stick with ab class amps with on-board DSP that make a good sound
I mean the old 2.1 systems like
MicroLab M_560

Bc I don't have enough money to buy good D class amp ...

I used to own this MicroLab M_560 and the sound was satisfying... Untill it started to buzz on idle
