Hypex Nilai500DIY Amplifier Review

[maty]

Nonsense.

They are way more than just audibly transparent.

That is the theory (I know well) but the test shows that they sound different, being very evident in the piano track, where the difference is spectacular (Purifi sound is very bad vs Nilai).

 

[AudioSceptic]

No soldering needed.

For that matter, the speaker cable is terminated with ferrules where it contacts the binding posts.

Thanks. There's no downside then, compared with buying one ready-made (soldering is one thing I might not do as well as a pro).

Remember that this is THD, meaning the harmonics of 10 kHz are 20 kHz, 30 kHz, etc and 15 kHz are 30 kHz, 45 kHz, etc.

This is intentional by design: maximize feedback loop where it is audible and let it go where it is inaudible.

That makes sense thanks. Was gonna ask about it too.
A problem for the eye as amir often says

I am waiting for my Nilai Stereo kit ordered from the manufacturer: (https://www.diyclassd.com/product/nilai500diy-250w-stereo-kit/185)

Price is € 1,225, plus shipping, no VAT added for US sales.
Shipping hopefully at the end of March 2023.

Another informative, impeccable, in-depth review. Thank you Amir!

If you are comfortable with small appliance or automotive repair, likely this build will go easily for you.

While the Hypex instructions are quite good, here is a tip if you are experienced. Put the side panels on last. There are a few connectors that are easier to attach with the sides open. Most notably the large JST on the power supply, case ground and the speaker outs on the amp.

For once no poor vote

I'm curious about these kits. How much, if any, soldering is required?

There's a vid on YouTube and the Hypex site. Looks easy.

Totally agree, it was shocking how different they were.

 

[Noob]

Wow, this is niiiiice!

 

[phoenixdogfan]

That 78db SINAD at 15Khz at around 30 watts is maybe a party breaker for the younger friends but for the older (like me) is just a spec.

Thanks Amir!

Yeah, but my dog won't like it one bit.

I'm gonna order the stereo one I reckon. Would like to hear it in real life first though.

@amirm on one of the graphs "grain" was typed instead of "gain".

So you claim you hear a difference without having heard it?

Is this some sort of next level to hearing the difference from the kitchen?

I don't need a new amp. I don't need a new amp

This is my mantra right now as I stare at at the PayPal button in my Cart...

Zero soldering required.

Clearly, designing these amplifiers and modules was a labor of love for the Hypex team. Everything is thought out so well.

I've had my monoblocks for one month, purchased from Deer Creek Audio. Really enjoying them.

Did you not listen to the YouTube video?

Not following too well buz. The difference was huge on the vid, I would therefore consider buying one after hearing it properly.

 

[Buckeye Amps]

Judging how an amp sounds from a YouTube video aside….if someone is going to compare two amps and how the sound in person, at least do a proper blinded A/B test.

 

[buz]

Did you not listen to the YouTube video?

No, the fiber coming into my apartment would screw with the result as opposed proper copper...

(listening to audio equipment via YouTube is a special kind of special....)

 

[AndyBeckett]

I do hate repeating myself, I am aware that a compressed opus audio stream is not good enough for a true comparison. However, if you can be bothered to watch the video you will be able to tell a difference (if your system is as revealing as mine).
