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.

Slainte,

Jim


Hi Jim
It's looking good.
That DAC has been around for a while, Richer sounds were selling it
so one particular mag gave rave reviews so as to perk up Julian.
It is also badged up under other brands (in the old days that was
known as faceplating):

Anyone reading who wants to give Jims excellent project a go,
the DAC can be found in an online search under the term "au-d3",
Can be got from ebay for about a tenner.

Previously when I checked it out it was impossible to locate a spec
sheet for it or anyone who had actually opened one? But will have
another look later today. A guess is it is the same intergrated chip-
Filter/2xO/S, into conversion found on intergrated MoBo chipsets
or soundcards etc.
