Maybe why some think so, but certainly not a sign of good design. Lots of people liked the old 1980's open loop Tripath class d amps too. And lots didn't.

My opinion is that the top end is definitely rolled off.   That's what happens with open loop class d amps...

@donnylovely  Come back after you have learned something about class d. I have made the issues with this amp abundantly clear to anyone with a minimum of technical knowledge about class d amp design. You can find the data sheets on Mauser, and th...

@donnylovely      You obviously haven’t looked at the design to tell if that's true or not. . Where are these mythical measurements of yours?     I have looked at the design and the data sheets while you clearly haven't. Nor do you underst...

@donnylovely  Old tech, this is class d circa 1985. Without any actual understanding or knowledge of class d, that doesn't mean anything to you. The technology has matured and is now capable of much better than out of date designs without post fi...

The module was measured at different impedances: 16 ohm......up .15 db at 20K 8 ohm ......flat at 20K 4 ohm........minus 1 db at 20K (quarter db down at 10K) 2 ohm.......minus 2 db at 20K. (half db down at 10K)     So the output filter was...

@donnylovely They’re too scared to actually listen to it. What if they actually like it? Their brain might melt.   Scared? Of what? Lol, I've read a lot of bs here but that sets a new standard. Is there some logical reason that an amp can't...

@donnylovely    Your GaN measures poorly compared to Hypex, Purifi, Orchard, etc. That's a fact. You say the GaN sounds great, that's just your opinion. I know people who think their computer speakers sound great. So what. Opinions mean nothing....

@donnylovely 1db is more of a non-issue than an issue. Sorry we can’t all afford to buy the best preforming amps in the world, that’s more of a non-issue also, always going to be something that preforms better.   Now you actually admit the fr...

@atmasphere Gentlemen. I see that @kuribo has entered this thread. I've crossed swords with him in the past, but on this point of load dependent frequency response he is correct. Nice to see we agree on something. To properly evaluate the pe...

Speaker loads are rarely purely resistive nor are they flat.

@donnylovely Maybe this will help... From: https://sound-au.com/articles/pwm.htm Class D Audio Amplifiers - Theory and Design 6 - Output Filter Design The output filter is one of the most important parts of the circuit, as the overall effic...

@art_boston Seriously? This is certainly something to care about, if you have any clue about amps. He is clueless, don’t waste your time. The FACT is open loop (zero feedback) amps are load dependent - the output filter interacts with the loa...

Who's delusional- the guy talking facts or the guy in denial who literally bought the koolaid, too dense to understand the technical explanation? Ever heard the word "bias" before? I can see I am talking science to a zealot. I would have to be de...

It's clear that the meaning and implications of load dependent frequency response are over the heads of many here. It's of no use debating with those who don't even understand the issue at hand, yet argue any way. Pure ignorance. And, lol, no, po...
