WRONGYes, Hypex data are ALWAYS power peak and not continous. MARKETING. Many have fallen, for not striving to inform themselves properly. Usually compulsive purchases or reviews that do not inform as they should.

Your office is nicer than mine .Its not a lab. Thats the office. It just happened to be convenient to do the video there for various reasons.
In any case we arent making satellites, clean room conditions not required and no, static is not a problem.
Fair comparison (even if DIY / OEM comparison is not really fair) is with FA252 @ Eur. 385.Nice to see another hypex solution.
I still find the plate amps a better value if you can DIY your own case. A fa251 is way less than what the OEM's want for a fancy box.

and CMR only 71 dB.
PSRR?
The PDF is well specified. Sellers/assemblers, not all, who cheat by not specifying that they are peak watts and not continuous.
BTW: "Apply sufficient cooling" -> bad idea a closed box without enough holes (and at the least harmful site, far from audio electronics) and/or heatsinks.
I wrote TRY with RF/EMI fitlers. Sometimes it seems that I should use more rich edition.
I like to check things for myself, hence I bought a cheap second-hand AVR to experiment with it and then apply it to a new one. The problem is that now it sounds great and I have FM Radio to listen to classical music and learn (they have a low quality MP3, despite being public). As long as I do not verify it for myself, I will keep writing try. If I build the only class-D amp that really interest me, PURIFI 1ET400A, I will do the test. If there is or does not improve, I would tell in ASR, even if there were those few..
If it does noy need it, much better, we save our money!
In
PURIFI: short term 450 watts at 4 Ohms. Then, 1/5 -> 90 watts continuous at 4 Ohms (without protection being activate, it is an estimate). It is a very good value to my speakers and without problems if I switch to a larger room and more demanding speaker! The calculations are overestimating the required power, so I will not fall short.

@March Audio, I'm sorry, but IMHO, that is not @maty who is wrong, but datasheet from Hypex. I still don't understand this "50W continuous power". Also, thanks for clarify power specs weren't peak either.@maty Already demonstrated you are wrong. Watch the video. It sat there before the test warming up at 1/3 power (80 watts) for over an hour before the FTC 5 mins at 250 watts.
Also there is a very good reason to not have RCA inputs on the amp.

Yes, but thats not the issue here, its his ignoring of information and explanations that are posted and propensity to spam every thread with masses of irrelevant information.@March Audio, I'm sorry, but IMHO, that is not @maty who is wrong, but datasheet from Hypex.

Perhaps. The datasheet has been updated quite recently (July 2019). Still, neither @amirm unit or @March Audio one is able to reach 200W/8ohms.Perhaps the board was revised and Nord still has the old ones.
The max input being given at 6.61dBu (1.66V) for 250W/4ohms, you may theoricaly reach that amount of power with a 2V DAC. Unbalanced is not recommended by Hypex, however (though I actually use RCA with two monoblocs - NC250MP with no "audible" issue). I would say the ADI-2 DAC is the perfect match for this kind of amp. What is your DAC?If I have a DAC with a 2v rated output, is that RMS or peak and can the typical DAC reach a peak output higher than the typical 2V rating? In other words, what do you really need to drive this module, especially if you don't have a balanced DAC?
