Default Where can I buy a USB Sabre DAC?

Hi

Lately, I decided to try DACs from different companies.. I also want to include in my tests a Sabre DAC..

In ESS's website, it seems that all their DAC chips expect to communicate in I2S, and unlike other companies that create DACs, they don't have some chips that include a USB controller built-in (so the chip would be a USB Controller + DAC).

Can anyone please recommend me of a DAC Product or Board that is Sabre based, and has USB connectivity? (and hopefully in a reasonable price also)

Alternatively, Is there some way to get a USB<->I2S board, which can then be connected to any DAC that expects I2S? (do all DACs that expect I2S communicate the same way over I2S, or it changes. If it changes, then it makes this second question irrelevant..)

Thank you very much

eBay/Alibaba and modify it seems a solid way forward.

I picked up a es9018k2m with a sa9023 USB to i2s receiver for less than $15 USD.

Great, I will check these 2, thank you very much.

BTW,
from what I read in ESS's website,
ES9018K2M is the 2-Channel version of ES9018 (which is 8-Ch).

So in that case,
What is the difference between ES9023 (which is Stereo) and ES9018K2M (which as we've seen is also Stereo)?


From ESS's website it's quite hard to see any difference..

If you do a search for "es9018k2m USB" on eBay, you'll find several vendors. Not sure which one I picked (I'm at work). These boards are all powered by the USB, so getting off of that plus tapping the inputs for a I/V like the one "vicnic" described will benefit you handsomely.

edit: Chinese ES9018K2M I2S DAC

Similarly, you can work with the 9028q2m or 9038q2m boards. They're all quite solid.

I've not seen the DS for ES9018K2M but in my understanding that's not a complete solution in that it needs an output stage (normally some opamps implementing a differential-SE filter) and power supply to create a complete DAC. ES9023 on the other hand already has the necessary opamps built in along with a power supply for them.

And a charge pump to create a ground-centered output (the ES9023), ostensibly eliminating the need for AC coupling.

Yes - that's what I was referring to when I wrote '... along with a power supply for them' of the opamps.

Should I conclude from these 3 posts that I should get the ES9023, and not on the ES9018K2M?
