Number of DSD recordings in my colection is zero ... I'm more interested how it sounds with regular stuff.
I have ordered one, i will give my take on it when it arrives its not expensive and usually not hard to make AKM dacs shine in my opinion.

I listened the Chinese AK4396 board.. after that, I heard the same chip implemented correctly, the difference is huge..
Possibilities which AK4490 offers are enormous, native DSD is only one of them..
Read the pdf and you'll see just how many things is on this desperate board is left out..

This is like saying "I drove a Russian car and it was terrible. After that I drove a French car with the same engine and it was much better. Therefore, there is no possible way that this other Russian car, made by some different company, from a different design and parts, can be any good."
The logic is just non-existent.
Listing says:
"Using original AK4495SEQ, op amp AD827, LT1963-3.3 "
Name of the listing states AK4490EQ DAC presence...
This is one reason i wouldnt buy this kit at the first place 😉 In the end you might get AK4399 with fake opamp, or even worse... With a bunch of cheapest caps on the market. On the other hand - why should you expect more from 30USD? Its the price of PCB only🙂

I noticed this, too. I don't care. The 4495seq looks to be a great chip.
Caps can be replaced easily, and it is fun.
I have all sorts of genuine opamps around.
For someone willing to mod and tinker, the board offers plenty of value, IMO.

The listing says AK4495SEQ, so I am reading that pdf. Digital options are irrelevant if I don't need them (like DSD). The analog output sections described in the pdf look simple enough to me. If the board gets it wrong, I will fix it.
It seems like the reference to the AK4495SEQ has been removed. It would also surprise me if it was really the AK4495SEQ, which is much more expensive than the AK4490.
I am bit surprised by the choice of op-amp. It is not exactly low noise or intended for audio applications, but it might be OK. I have no experience with it myself.
The AK4490 is an interesting device and I am working on a design using this part.

Got it today I was happy to see the little box in the mail only to see when i opened it up there is a AK4399 i2S DAC in there so here we go with emails to the ebay seller: sep_store, Assembled AK4490EQ II2S DAC board support 32BIT 768K decoder -sn #121605526008.
This one looks a bit nicer - plenty of matching USB>I2S kits too:
768kHz/32Bit AK4490EQ DAC, I2S/DSD input - DIYINHK
768kHz/32Bit AK4490EQ DAC, I2S/DSD input - DIYINHK
In what way is it nicer? Doesn't seem very good value, considering you have to add your own regulators and power supply.
I see no value in a complete board loaded with potentially poor/dodgy/fake components and the wrong DAC chip. The DIYINHK board does need additional external elements to function, but most of us would be buying these bits anyway to replace the low quality ones on a cheap finished DAC PCB. The Hifiduino report on the DIYINHK board is pretty positive - seems like a good kit to start with to me....

Sending a board with the wrong DAC chip is disappointing, sure, but assuming that's it's a a mistake rather than deliberate, I think the correct board represents good value, even if one has to swap a few parts to get the best out of it. If someone doesn't want to do that, then sure the DIYINHK model may give more peace of mind, but it does have a lot fewer parts in hte first place, and therefore requires even more expenditure and effort to get working at all.
