Sui Katase FN1242A DAC

[jean-paul]

Very nice DIR9001/FN1242A ("Fluency") DAC from Japan. This particular DAC chip really is something else as it is quite unique from a technical point of view and it was made by Niigata Seimitsu who normally produce medical electronics.... Luxman used it in various flagship devices. I built it up with Black Gate caps both STD and NX-HiQ. I tested it and encased it but never used it. Since I needed the casing I dismantled it. I can include 230V transformers as shown on picture.

* Apparently the DAC PCB can be modified to DSD but I have spent enough time with Google translate The chip is relatively unknown outside of Japan and it was not intended to be sold to private persons but somehow a batch ended up in Akihabara (秋葉原) in Tokyo. This is why almost all FN1242A designs come from the land of the rising sun.

Make me a good offer.

Bump. Price is 100 Euro ex shipping. Considering the quantity of BG caps this seems a good price to me. Output buffer is a metal can LM49720. Low noise symmetrical PSU and LT3080 PSU are of course included.

Sold!

Hi Jean Paul
What a great pity, just wanted to contact you and buy the DAC, but forgot to scroll down first.
BTW: Did you get my pm concerning the LM4780TA. Although the ebay name of the seller indicates that he is from china, it is a decent German seller. I get my chips tomorrow.
Kind Regards
Phil

Hi Phil, yes I got the message. The board was sold anyway so I will have to stay happy with my current setup

DAC is coming in 10 days to Russia in great condition, and perfectly packet.
Thank you, Jean-Paul!

PS: Waiting for tubing instructions....

Hi it does not need tubes with such a well thought out output stage but of course you can add an extra stage. However, extra is superfluous
