Just to let people know I've now put up a page on a new cheap and
simple DIY headphone amp at

http://www.audiomisc.co.uk/HFN/HeadDAC2/HeadDAC2.html


There are purpose-designed chips for low voltage single-ended supplies
that would seem to be a better choice for a headphone amp running off
of just 5 volts.

Quite likely. I doubt I'd have done it this way for a from-scratch design
for myself. The main point here, though, (as explained on the webpage) was
something as 'un-intimidating' to newcomers to practical electronics as
possible. In effect I wanted to hijack an existing cheap (8 UKP) and easily
available (CPC) kit. To make something seem feasible to readers of a
magazine like HFN who've never before dared to try making something.

Once they start, I'm sure we could coax some of them into deeper waters...

Slainte,

Jim
