China ... another clone, another dollar

 

[Matias]

Fake and expensive? Good luck.

I have a serious problem with China pirating technology. This seems like an example of exactly that.

This is definitely a pass when I know I can get a VTV unit for only around $300 more. I own an Aiyima A07 and I like it. I also own a Purifi Eval 1 I assembled from parts, and I love it. IMHO, Aiyima should just stay in their lane.

Not really shure it is an Aiyima product. It seems really sketchy.

It is just a DIY home-brew type of product I think. Not a fake. Already tested by Wolf few months ago:

Measurements of Lm Audio MIN400A ClassD PowerAMP - L7Audiolab

台式设备 其实早在过年前就有人和我说过 Im Audio MIN400A 这台机器的存在，我当时也联系了卖家说能不能借我一台测一下，但是由于种种原因（疫情、缺货等等）就一直拖到了5月。前几天终于收到了最新一批的机器。这台机器是DIY产品，送测来自DIY商家。

Wolf tested the one w/o volume pot.

Silly name the seller has: "AIYIMA SMSL AIYIMA SMSL Amplifier specialty store Store" LOL.
They probably will have a sister outfit on Aliexpress called: "Apple Lenovo Samsung Apple Lenovo Samsung specialty store"

Those do look like excellent measurements, and the boards do look like 1et400a Purifi boards, but still I think overpriced, with a highly dubious warranty. Also, I don't see any Aiyima branding. And this also raises the question whether whoever is selling this is infringing on Purifi's patents, and if this unit uses stolen intellectual property, which I, for one, would want no part of.

Thanks man. In fact it seems like a very interesting amp, judging by Wolf´s measurements.

 

[Dmaumau]

@WolfX-700 could you tell us anything else about this amp ?

How the fuck can a Class D DIY project perform this well?

If anything the measurements confirmed it's a fake. and from the looks of it a really good fake.

May be a copyright lawyer can chime in here. It is obvious you are not getting a Purifi Module inside. The seller is playing the title/description game as "1:1 Replica Hypex Purifi 1ET400A" which does not even make sense. A "Purifi-Clone" it seems what it is inside or what they want you to think it is. Like many of those "Marantz 7 Clone", "Matisse Clone", etc. out there I guess.

If you're going to get a replica, why mess around with a fake Purifi?

Get a Pass amplifer instead. Especially one with bile flavor. Yum.

Don´t think any lawyer will chime in about any chinese clone and copyright laws in Denmark.

Hmmmmm bile flavor ? If the shipping costs were less than 55% of the bile price, I would order one right now.

China has become synonymous with Fake, a problem which goes back decades when the Chinese government introduced a policy to encourage this shameful practice.

Here is a listing of the same product from a different store, with more photos and information.

The seller is playing the title/description game as "1:1 Replica Hypex Purifi 1ET400A" which does not even make sense.

On AliExpress, titles often don't make sense because vendors throw in words to make the listing come up on searches. The one I linked has the title "Class D digital power amplifier Purifi, hypex, 1et400a, LM, UCD, MIN400A". Obviously they want to catch customers searching for hypex amps, hoping that they'll consider something else in the same category.

Might be fake, might not be fake. You don't know until you measure it and check the board. These modules are produced in China, so wouldn't be surprised if the same factory produces some extra on the side.

Might be fake, might not be fake? Seriously??

It's marketed as a "Replica Hypex Purifi 1ET400A"

Please refrain from spreading stereotypical impressions, Chinese manufacturers aren't just about cheaping out and copying others' designs, there are original designs reviewed here which turns in above-average performance at acceptable prices.

Besides, looking at the measurements, at least the (reverse) engineering on this particular clone was sound. Yes, this absolutely goes against what intellectual property is all about, but this device can be a friendly introduction to high-performance, high power class-D designs for local enthusiasts who are a bit short on budget, some of which will, hopefully, convert to "OG" purifi or hypex when they have more change in their pocket.

With all that said, I would agree that it's a dim move for the company to try selling them outside the country, especially since module/machine pricing for real purifi modules are more reasonable, and budgets much less constrained compared to within the country. Leaving this clone uncompetitive in pricing, and short on originality.
