To give credit to ismosys, I got all the datasheets I asked for after signing an NDA.
The continental Eu representative has been very helpful. Thank you Olaf.
Best regards,rope

Yes Patrick, I find Jo from Ismosys, very responsive to requests.
Have you used the new ES9022 DAC yet?

Can anyone who has seen the datasheet give up the output DC offset numbers of the ES9022 or is that covered by NDA?
I've got a project that works with the WM8524 and was considering the other chips. However the AKM chip is going by the wayside as its output offset is too high for it to be DC coupled.
Guess I should talk to a North American rep...

Hi, I'm from the Philippines, Is it possible to order from your store? i'm interested with 50-100pcs ES9022.. I've tried to contact the Asian distributors but got no reply.. thanks

Ismosys is only agent for Europe. Try an Asian distributor first.
If all fails, I can order for you, if you pay in advance.

Hi Patrick,
I'm truly grateful to your offer.. thanks very much..
Yes i already contacted them several times this past few weeks but haven't heard a word from them..

They are UK based. Very good service, although they are probably closed over Christmas.
Line One will almost certainly sell an ESS9022. If another supplier is no good, they may be able to help.
Hi Spartacus,
I tried ordering an ESS9022 from them months back & they didn't have any in stock & didn't get back to me about ordering in - I eventually ordered them through Ismosys but find their postage charges high.

I thought I should put this on record :
FAA, alias Arvin, asked me to get 100 pcs ES9022 for him. I got a quote from ismosys, together with some stuff that I wanted. He then asked me for a copy for the data sheet. I got mine under NDA, so I got him in direct contact with Olaf of ismosys. Olaf has not heard from Arvin since. In the meantime, I purchased my own requirements online at the ismosys site.
As such, I have no further dealings with FAA (Arvin) regarding ESS DACs, or else.

How does ordering through Ismosys work?? I registered an account, and for shipping options, it has a customer shipping option to enter a courier and account 😕. How high was shipping for you, and how would i get a shipping quote before paying?

So I finally got my ES9022 going.
Oh, God. How nice !!!
I have been listened for four hours, and I still cannot decide whether it is better or worse than my (not too exotic) reference -- Meridian 508 modified.
It has better sound stages, but perhaps a tinny bit less sweet. Maybe I should play with the output filter a bit more.
For the money, it is unbeatable.
Photos tomorrow, if the sun comes out.
All credits to John for the tip. 😉

PS I did not follow the datasheet straightly, as you would expect from me.

I told you Patrick - this DAC is a value for money find 🙂 - not the best DAC in the worls spec-wise but it's sweet sounding nonetheless. Even sweeter when plugged into a modified HiFace USB 24/192 transport via I2S & driving headphones for instance 🙂
Let us know how you differed from the datasheet - I did too 🙂

Only you and I interested in the ES9022 ?
What a pity. They don't know what they are missing. 😉

Someone PM'ed me and asked a couple of technical questions about the chip.
There is next to no details in the datasheet other than the pin assignment and a typical application schematics.
For the little extra that I know, I am under NDA.
If you want to find out more, please contact your local agent and ask them to ask ESS.
That is how they want it, so that is how it has to be.
Anyone can afford the price of an ES9022, so there is no reason not to experiment.
Considering some of the effort that went into a TDA1543, I am sure this also deserves the same.

Yes, Patrick,
They don't know what they're missing but I've seen some people raving about what this DAC has to offer - the users of NuForce uDac USB/headphone DAC which uses a ES9022 FIRST IMPRESSIONS: Nuforce uDAC USB DAC AMP with line out and S/PDIF out - Head-Fi: Covering Headphones, Earphones and Portable Audio
I've been asking there & here about the innards of this uDac but nobody is interested.
BTW, do you have the ESS application note for this ES9022 - email me & I'll send it to you.

The ES9022 looks like a good chip to compare against the work that I've done with the WM8524:
The GrubDAC - Head-Fi: Covering Headphones, Earphones and Portable Audio
That being said, for me, dealing with the NDA seems like a big hurdle. I'd rather make a board that a diy'er could get all the parts themselves.
