Hypex Nilai 500 DIY Stereo Amp Kit Review

[Method2Madness]

Wait, wait, wait....y'all completely trash amps costing much less with similar performance, yet you're completely salivating over a $1400 amp you have to assemble yourself?

I uhhh....yeah.....

Which amps are you refering to? I'm curious, add some substance to your claim please.

There are residuals from 60Hz/180Hz/ff which I don't have with a neat Hypex setup. Also the noise around 10kHz ...
I really like the new NCx252 module - easy to handle, low noise and even lower THD as the previous version.

Im surprised at the high levels of imd in the bass, some 30db worse than one if Tom's neurochrome amps.

Hi.
I have made 3 DIY amplifiers of this 'format' myself and none of them ever made a noise when turning on or off, that's why I didn't put 'golfing panther'.
It is a very nice realization although the price is a little too high in my opinion.

And I had two Nilai 500 monoblocks. They popped when I turned them off and on. I returned that junk. Hypex is dead to me. If it's Class D, then Purifi. That's my opinion.

What power supplies are you using with your Purifi amplifier modules?

Sorry. I worded that unclearly. I meant that if I buy another dedicated power amplifier, it will only be a Purifi. Probably the 9040. Currently, I'm using an integrated amplifier, the Rose RA280. I bought it used for a good price. It sounds decent.

Of course I know this measurement. But the Nilai monos that I had popped everytime. Turning on and off. Thats why I sent them back.

I have never noticed my Nilai popping when I turn it on and off. But, I am turning it on and off with the 12V trigger. Perhaps that has something to do with it. I don't know.

How loud was that really? A pop or a pop, there's a difference. If it was noticeably loud, it can't have just been the 3mV measured here - rough calculation says 3mV knack into 90dB speakers makes 30dB, which would almost vanish into room noise. It must've been much worse than that then. Amir measured the Audiophonics NC252MP implementation to do 20-50mV switching spikes, and mine is barely even audible here, really a very tiny knack that's utterly negligible.

Hi.

A device designed rigorously and according to the rules of the art must not emit the slightest 'pop'.
They should all be inspired by the TOPPING B100 and B200 models, which are exemplary.
A measurement below or equal to a maximum of 1mV can generally be considered acceptable.

But it doesn't affect listening. Why do you care?

Please tell me more about where this rule is written, and why of well over 70 audio devices I owned, about a third were apparently not "designed rigorously" despite being made by companies like Korg and Yamaha. Professional equipment.

In practice, the pop must be small and insignificant, as to not pose any danger to other equipment, and that's it. A little pop is completely normal!

Korg and Yamaha are not necessarily references, even if it is probably the case for you since you mention them...

My point is that even professional equipment isn't always perfect in the way you seem to think it should be. Engineers and users don't think it matters, because it technically really doesn't. Only a few super nitpicky borderline OCD hifi guys seem to care are all.

How about Genelec active studio monitors? I dare you to claim they were not "designed rigorously".

Maybe, but this is just your point of view, which is purely subjective.

Don't lose sight of the fact that this site is 'scientific' and therefore based on objective measurements, and what's better is: that's all.

You can't question this, even if you don't like it or don't 'suits' you.

What is achievable, when it is excellent, must be the minimum objective to be achieved by a manufacturer if we want to see the technology advance, otherwise what is the point of making measurements and in this case coming to this site to see it ?
