Hi, these were the transformers I used most in DAC projects. I have the datasheet available. They are 1:1 transformers shielded by mumetall. Both have the same datecode. They sound excellent which is backed up by their properties as described in the datasheet. Haufe transformers are often used in quality studio equipment and broadcast gear.
As I just stumbled upon the pictures I took I don't have the actual data available right now. I am thinking of 100 Euro incl. shipping within Europe for both. These were soldered and desoldered with tin/lead solder and have not been overheated and such. They measure identical (as expected). As usual these are allergic to DC so make sure you have low offset of use caps in series.

JP - thanks for taking the time to get the measurements. I know that Haufe makes great transformers. Someone will be getting a good deal with these.
For my experiments, I've decided to go a different direction. I already have some larger transformers that I'll wire up external to my DAC. I'll be using them with an AK4497 based DAC and I want to try these for converting the differential outputs to filtered single ended.
Thanks,
