Hypex Nilai 500

**Alkyogre** · October 31, 2022, 05:55 PM

Today sales started for the new Hypex Nilai and I ordered a set of monoblocks.

**Alkyogre** · January 28, 2023, 11:31 AM

The mono blocks arrived, and I had to assemble it myself. The Diy assembly was not difficult, with these nilays you don’t have to solder anymore, in a few hours everthing was build the mono blocks where ready for use. What also is new, is the powerbutton on the front and the blocks don’t use many power when they are idle.

Remember: the previous hypex NCore modules where also used by NAD in the c298, which have very positive reviews. I replaced my old NCores by these upgraded Nilays,

I had a decision to make, in build there is a switch module, it means with a jumper you could choose the output power to low gain, mid gain, or high gain. With my Bryston preamp high gain was far too much, I chose low gain.

The result was a big step forward then my old NCores, much more stereo depth, and the lows sounded impressive

These mono blocks perform above my expectations, I am very happy with this improvement.

Any info on your build , PSU size, type etc, what kind of load do you have them driving .? Did you try increasing Sinks ..?

To make things clear, I opened it and took a picture. You see above the amplifier unit, and below the internal powersupply.
It does come with a 500W powersupply, It is 525W at 4 ohm and 260 at 8 ohm. I think, looking to all those capacitors it must be an LPS.
distortion is 0.0005% between 20 Hz and 20kHz
It does come with 1 balanced XLR input and a 12 Volt trigger.

Input sensivity is 12 V at low gain, 3.8 V at mid gain and 1.9 Volt at high gain.

size is 205 x 80 x 300 mm and it weighs 3.45 kg

The guys at @TheAlphaAudio did a listening test, which included the Nilai kit. They were really impressed with the newest offering from Hypex.

Who would sit through two hours of that?

Agreed.

IMO, GaN is the Class D that sounds best.

Great that they liked the Nilai. For info, a former Philips engineer worked for both purifi and Hypex.

I have them directly from the hypex factory. It is a bit confusing: the hypex site is only for professional businesses, consumers need to get it from diyclassd where I ordered it. Diyclassd is shipped from the same building as hypex.

Definitely has some juice as it doesn't buckle into 2 ohms. That's some serious squeaky clean drive power vs load. Thought you were a HE/horns guy?
Twill be dead silent with 100+ db sensitivity systems, but 500+ watts?? Bit of overkill IMO. Of course, for non HE, just the ticket.
See yuh soon.

cheers

**Alkyogre** · February 12, 2023, 04:33 AM

Yesterday audioscience review retested the Nilai. Originally he had a bit of noise pickup at 10 kHz, but he tested it with the top lid open.
After testing with the lid closed that noise was gone. Why does ASR measure an amp and post results while it was still open?

That having said, with this retest it is one of the best amps ever measured

Where is the "review"? I only see lots of measurements.

**Alkyogre** · February 12, 2023, 10:44 AM

Scroll down. Although I have to agree that he is saying not much in his conclusion

Conclusions
It is clear Hypex is taking competition in class D amplifiers seriously responding with a DIY friend amplifier solution that has a ton of power and wonderful performance. While we could nitpick here and there, but in the larger context of the amplifiers out there, this is a superb offering of great performance and lots and lots of power.

FYI I don't have pricing for the kit. If someone has it, please post. I see online ads saying around $900 to $1,100 for a single channel.

I am happy to add Hypex Nilai500DIY amplifier and its companion PS500DIY power supply to my recommended list.

That's not a review, it's a closing statement after his testing results.

**Alkyogre** · February 12, 2023, 11:11 AM

That is audioscience review. All about testing by amir alot of graphs to look smart and scientific and alot of followers. A comedian once said: the more complicated you talk, the more scientific people think you are.

Meanwhile, who is checking the test setup Amir is using? Such a lid, it is a matter of only push pulling. With this blunder I seriously have my doubts if these testers know what they are doing.

Having said that, I prefer this forum much better, people who listen and compare is much better then all those testing with these stupid SINAD scores.

No horns here , that was MEP , he got tired of clipping his AR on his NOLA's and switched to , a Quasi horn setup........

anyway, the HYpex current limits heavily into 2 ohms , but has enuff there to make do , problem is heat soaking driving low Z and PSu sagging, big sinks or a fan like crown does on their class D will help here. problem with ASR is no sine waves to clipping pics , would love to see the symmetry and of course they are allergic to square waves. Amir tests are skewed to make class D look superior and in some respects the measurements are excellent , but its not the whole picture ..

tempted to give one a go , low heat , low draw when just doing casual listening would work for me no need to run the behemoth for casual listening time ...

regards

Cool, nonsense and sense in one sentence. 500+ into 2 ohms for a 250/500 8/4ohm is plenty and good performance, especially for the ridiculously low price. A great many "audiophile$$" amps can't drive 2 ohms and unless the speaker has idiot "injurneering", that much power>load would be more than suffice. Hopefully I didn't insult your mystery speakers.

Actually it is the whole picture. His and JA etc who do test, show that the Hypex, Purifi et al are superb, transparent amplification, capable of outperforming human hearing, including yours, in the really, real, non-imaginary world. But that doesn't mean the sight and "knowledge" of them can't/won't lead to audiophile melodrama. So YMMV.

Well, unless the secret speakers are low sensitivity and/or audiophile injurneering impedance, they will be every bit as transparent as other well designed SS, at any sane level. As I will continue to demo, In public.

Si yuh soon.

AJ

Explain to me at what level is your understanding AJ, apparently i keep speaking over your head

200 into 8 is 800 into 2 if no current limiting , so 500+ into two is serious currently limiting , this is basic even for a Campion nutter , this level of limiting ( and heat soak) will rear its ugly head , on anything but a 8 ohm speaker well for those who interest is actually accurate timbre, drive and ultimate sound ...

So on a 8 ohm load i can expect decent sound , with the accompanying low Z of 4 ohm, not on a 4 ohm which could see 2 ohm , you should try and learn what phase angles due to amps with falling PSU and current limiting ...

BTW Audiophile injurneering is usually accompanied with digital eq, xovers , blah blah blah , mega compensation , producing poor timbre/timing, splish splashy sound at best , the deaf and blind can partake , something for
everyone ..

To each their own, heavy Class D lifting in public is fully supported , as is Class A, AB, SET, SS or toobs, so carry on ..!

How is that for nonsense and sense .......?

Regards .....

Yes, my formal EE education, microwave/radar/satcom/30+ years of varying engineering work, actual products and public demos, puts me at a serious disadvantage to an audio forum expert like yourself Mr Wayne.

Without serious cherry picking show me the list of real world 200w/8ohm amps putting out 800 into 2 ohms...and I'll show you a list 1000x bigger that can't. If 500+ into 2 can't drive your mystery speakers, that's purely on you. More than plenty current for the 99.99% of non-pathological engineered speakers. Since you're understandably way too embarrassed to reveal anything about your system, you can't even claim "well my amp can" ;-).

Like your system you're projecting. Well. we'll have to take your word since no one else will ever hear it

.
Unlike my countless demo's of electro-acoustics and perceptual knowledge. No hiding. See yuh in Room 1215

**a.wayne** · February 15, 2023, 07:21 PM

Fail to see where your experience has anything to do with audio , EE’s are dime a dozen even i have one , my Audio experience supersedes yours by decades with actual achievements , sales customers and patents not simple high school designs then walk around like a Big wig doing demo’s ..!

So yes you lack understandings in relations to most things audio , never questioned ur education , microwave knowledge or experience , makes sense now that top end could fry eggs ..!

Small hint learn up and show some respect goes along way in receiving some ..!

Yes we can arm wrestle in your room ..

I'll admit that your white van speaker business has been around a lot longer than I've been a company.
Too bad everything about you is always a secret, but that's understandable when its all purely imaginary+blah

FWIW, the amp is going to behave as a voltage source to within a couple dB of full power. So at normal listening levels the 2 Ohm thing really isn't a concern. Usually when you run into those 2Ohm impedances with weird phase angles its at a certain frequency and not the entire impedance curve so in practice this will be an issue for only a very few.

FWIW, when the amp is asked to drive a harder load its going to make more distortion too. I don't see the point myself- I've always had the impression that high end audio was about getting away from distortion and closer to the music. There are plenty of easier to drive speakers that sound just as good or better than those that are not easy to drive (and some of that comes simply from the amp making less distortion).

IMO/IME if high end audio reproduction is your goal, your amplifier dollar investment will be best served by a speaker of higher impedance and higher efficiency. If sound pressure is your goal, you have a (IMO) weak 3dB argument for lower impedances, along with which speaker cables become far more critical.

With all due respect Ralph, such nonsense , pushing lowest distortion mantra while designing high distortion toob amps, is just more cognitive dissonance than engineering, when does the distortion matter ? I have yet to hear your versions of high Z and efficiency best low Z , low sensitivity setups, (ribbons, ESL's, etc ) most of us are driven by results not meme's and well wishes...

Cmon man at least be genuine with your responses .....

I was being absolutely genuine; remonstrations of your word salad (2nd to last sentence of your post above) notwithstanding.

I was explaining how an amplifier that behaves as a voltage source works, in particular how it works when presented with a load of lower impedance than it can double its power at full output.

I was also explaining the downside of difficult speaker loads. To add to that- let's say you have a speaker that's low impedance; if you could have that speaker be somehow higher impedance it would sound smoother and more detailed on nearly any amplifier on account of less distortion from the amplifier. So it might 'sound good' to you right right now; if higher impedance it would 'sound better'. FWIW the extra distortion generated by most amps when dealing with a lower impedance tends to be higher ordered harmonics, to which the ear is keenly sensitive and also perceives as harshness and brightness.

Regarding when distortion matters: it matters when its audible. FWIW our tube amps tend to be quite innocuous in this regard. Our class D amplifier even more so.
