This is just to let people know that I've now put up a
webpage describing the design of the simple headphone DAC
I've been experimenting with during the last few weeks.
The page is at

http://www.audiomisc.co.uk/HFN/Headp...C/HeadDAC.html

The aim was to produce something inexpensive and easy to
build so that anyone willing to use a soldering iron and
drill some holes in a metal box could make one if they
wished. :-)

It doesn't use any fancy items made of unobtainium, etc.
I deliberately bought all the bits from CPC so they'd be
easy to source. But if anyone wanted, it might make a
nice basis for experiments and no doubt could be
'improved' or tweaked in all kinds of ways. That said,
the unit described works nicely here and I'm enjoying
listening using it.

The big missing piece in this project is the measured performance. There's
some reason to believe that the transformer, which is rated at -7 dBU @ 50
might be pushed to over load in some applications.
