Hello again,
I found a board based on :

CS493264 as the DSP/Decoder
CS42516-CQ multichannel DAC/ADC/SPDIF receiver (192KHZ/24BIT/110db)
CM108 as USB input (I don't intend to use USN anyhow)
M61538 for volume control
OP5532 Opamps
Branded components like ELNA electrolyte, main board use Philips and Samsung's 0805RC etc...

specifications:

SNR:105db
Stereo separate degree:90db(1KHZ)
Frequency response:0db/-1.5db(20HZ-20KHZ)
Noise output frequency:200uv
Simulate output frequency:2.2v

All this at around 110$ shipped...
Seems pretty decent to me and worth the money - probably pretty good performances after minor upgrades - any thoughts?

I found two more promising items at eBay and consider buying the PCB kit's alone w/o chassis and Transformer (I have a local contact who can help me with that).
The price difference between these will stay the same - which one would you choose ? Why (considering Stereo quality is my highest priority and "fancy" DSP/LCD/Remote not really worth the added ~50$):
Very Similar to HLLY - probably OEM in the same factory:
2010 NEW HIGH END DTS AC3 5.1 DIGIT AUDIO DECODER DAC

Around ~50$ cheaper and less "fancy" which I won't mind if you think it'll sound the same:
LEMING AC3 DTS-6 DIGIT AUDIO DECODER DAC

I contacted the ebay seller about this kit and he says there is a DAC in there !

Pretty much exactly what I've been looking for - and the price is...OK I guess... (even though I don't care for the DSP nonsense and some of the other features...).
The decoder chip seems to be:
CRYSTAL CS493293

I couldn't (yet) find any info regarding it's "DAC" performance - how would it perform as a STEREO DAC?
Any thoughts?

But i wonder if they really are better than auzen and asus multichannel soundcard (though these souncards are internal).

Yes thats a good question !

People are buying them....someone knows.
It would be good if anyone with experience with these could comment.
