Approximate parts cost for the BOM above for 1 board (incl inductors) works out ~€6 or so. So I still need to check to see if that is incl or excl VAT (sales tax) and customs etc etc. But suffice to say the parts for 1 stereo board ain't gonna cost that much. I also need to estimate postage costs from me back out to the various countries with/without tracking. Based on past experience I'd image we are looking at ~€12-13 for the full kit for one stereo board minus tracking which usually adds €3-4.

PCBs are already ordered. FETs yet to be.
Longest time is matching and sorting.
So patience.

And we have not even collected money !!!!!

Question, is this buffer compatible and useful for the JP/Subbu ES9023+WM8804 DAC?

And another Q: I did look, but couldn't find the info - what is the current demand for the filter and what would you suggest for a PSU for it? Batteries or shunt, or is the PS not so critical?

Jean Paul was the third on top of the subscribers list ??
You should ask him.

> what is the current demand for the filter and what would you suggest for a PSU for it?

About +/-9V, 24~32mA, depending on the Idss of the JFETs, for stereo.

> Batteries or shunt, or is the PS not so critical?

If you ask me, of course batteries.

Hi Patrick,

I thought Joachim's schematic had +/- 15V?

The voltage is not so important, since you only swing 2.8V (line level).
So 9V min, 15V max. Max is limited by cascode JFET dissipation.
Anything in between is fine.
