After some test with No oversampling DAC chip I think that the AD1865 is the best.
If compared to the new technology DAC chips like AD1955 and CS4397 since to be more natural.
The old TDA have a too close sound and with these some particulars are lost.

But where I can get some AD1865 chips to create a kit ?
Someone have tested the AD1861 or the AD1851 with th esame technology ?

Did you try PCM56 ? Same as AD1856 = 16 bit version of AD1861.
Best IMHO.
Every kind of TDA sucks, right.
Do you use an analog filter ?
I tried everything from unfiltered over transformer filter to active & passive brickwall and passive brickwall sounds best.
Your THD numbers seem to be a little bit.high.
Why only show spectrum to -80dB ?

No digital filter
I/V converter made with a Caddock MK132
No analog filter, in the final version a LL7903 wil be used to increase the output voltage and tii create a natural filter

I cannot find a shop to by the AD1861 or Ad1862
A question:
- also the new product dac like ad1955 could be used without digital filter and no oversampling ?

You will have birdies all over the place... and intermodulation poducts. What is a "natural" filter?
My question was addressed at Bernard though.

Sorry I have to correct myself; I have only for sale the 16-bit AD1851.
(The AD1861 is an 18-bit DAC)
How would you use an 18-bit or 20-bit DAC NON-OS anyway? Not using the MSBs will make it sound very faint.

Folks, the excitement is building and it is only a matter of time before the worlds first 1-bit NOS DAC is announced right here in this forum!
