Deciding Between NCX500, Purifi Eigentakt and Nilai

[MaxwellsEq]

One more question, much fuss has been made about the Purifi 1ET400A Eigentakt by reviewers. What is it that distinguishes the Eigentakt from the NCX500 or Nilai (if anything)?

One of the designers (Bruno Putzeys) wanted to change loop structure to improve load tolerance Bruno Putzeys on difference between ncore and eigentakt

As any audiophile can tell you, with that much negative feedback it must be unlistenable.

It has so much feedback, there's no output

Interesting read, thanks. Bruno says “The amplifier is not "DD". It's a straight self-oscillating fully analogue design”.

So the Purifi Eigentakt is an analog design?

This a bit about semantics. Some people mistakenly think Class D is "digital", but it's not in the classic sense. D doesn't stand for digital.

Where did you buy your Nilai kit?

Deer Creek Audio, mainly because they had stock and others were out. I found them great to deal with.

Check boxem on the purifi option, the auto on/off sense is the cats meow.

I think Buckeye is probably the cheapest and most honest seller. I saw on video on YT recently where he said the difference between Purfi and Hypex latest modules is negligible and best to get Hypex and save the money.

And the Amps look pretty nice also.

I’m getting ready to replace my 7 year old Emotiva BasX A300 amp. I’ve narrowed it down to three choices, NCX500, Purifi Egentakt or Nilai. After researching this forum it seems that all 3 choices will sound the same. So I’ve concluded the NCX500 would be the most cost effective. The Purifi Eigentakt seems to be getting the most attention from reviewers. The Hypex Nilai is the latest and greatest and the most expensive choice.

So the VTV NCX500 is likely going to be my choice. Am I missing anything?

I have the Nilai mono blocks powering my Focal Sopra 2 and they are killer!!

Nice. I have the Nilai stereo amp and Sopra No 1s - pretty nice too, but am a little mono curious. What do you use as a preamp? (Athena here)

What did you end up getting? I'm pretty happy with my VTV NCx500.
But I saw a YouTube video where people compare the 3 modules you listed and the consensus there was that Nilai is superior, so Id be curious to listen to it and compare.

Yes it's semantics. The only way class D isn't digital is if you redefine what digital means so that it fits what you want. Agreed - D doesn't stand for digital.

I saw you try and fail to successfully defend this illogic in the thread:

Audiophiles, generally don't like class D amps!

Ok, I know I shouldn't, but I've been reading feed back on an audiophile site on experiences with various Class D based amplifiers. (Purifi, Ncore, and a couple of others less well known to me) I expected a bit of bias towards older technologies, but it was close to 100% against class D. What...

Why try again here?

Because truth is more important than deceitful marketing

Oh, OK

I have no clue what Bruno is referring to, but all class D uses PWM technology, the PWM is typically controlled by an integrated chip. I wonder if he is referring to that IC chip.

I own a self assembled Hypex NC400, it is an awesome amp, very clean.

After that experience, I decided to get another Dutch or Danish class D for my main system. I ended up deciding the NCx500 over Purifi and the Nilai due to the combination of power output and low distortion. This time, I ordered it all assembled from Apollon, I ordered the dual mono version, it's taking forever, I ordered it on Dec 26th and it should come in next week, at least I hope.

With Apollon, you do pay a premium, but they have by far the best looking casework, very premium in my opinion, and they put a lot more detail into the assembly.

If you get the LUX model, per Apollon's website: "The chassis is custom machined from solid aluminium. 10mm thick walls and 5mm thick lid and bottom. For improved aesthetics we have designed the chassis in such a way that there are no screws visible when you look at the amplifier as they are only on the bottom plate."

I also ordered an NCx500 amp from Apollon around December 26th (Dec 29th).
It arrived today and goes into my rack tomorrow.
