Hi vadimgal:
Try to contact with you but I can't reach your email....
Please email me where I can buy D20400A, I need two of them. Becasue my DAC, SF D2MKII, power LED is twinkle..., can't send analog signal to my pre-amp, SF Line 3. My friend maybe my D20400A is dead.... Please help, thanks a lot. Here is my email: dyu@mmm.com

D20400A DAC
I would love to know where to purchase the D20400A as well. I have the the SFD-1MkII as well and the DAC is supposedly toast. $200 would be a small price to pay to get it going again. Please let me know where I could purchase these chips. TIA,
Carrington

I posted one Ultra Analog original dual DAC D20400A on ebay here:

I have an UltraAnalog D20400 that came out of my Ben Duncan DAC, which I would be willing to sell. It was working fine when I stoped using it a few months ago, I took it out of the sockets and put it into conductive foam.
I don't know what the difference between this and the -A suffix version is.
Message me if you are interested.

Here you can buy the whole Sonic Frontiers dac for $250, half the price people are asking for the D20400 alone

d20400 replacement
I just finished a drop in replacement for the D20400 in the Levinson No35. like the No30.6, It uses two PCM1704K and OPA627.
At first I thought there was a data format problem since the output was very distorted. But the problem was the No35 bit clock driver IC sucked. The long BCLK trace to the DAC is about 8 pF and the original IC MCxxxx could only pull up 0.5 mA. So a poorly shaped 1 V p-p is all there is, but for the D20400 it worked. The replacement SN65XXX delivers a beautiful BCLK and all is good.
I got the idea from the Levinson No30.6 where they did just about the same thing but their board is NLA and was $800. I also used dual PCM1704K and OPA627. So it also measures and funtions almost exactly like the D20400 but I included a 2 pole LPF to reduce out of band noise. I still need to try it in our No30 and No30.5.
S/n 114 dB un-wtd 22-22kHz. Low 0.0020% distortion with 16 bit data.
