The question - sorry! Does anyone condone setting a headphone amp-iPod combination up that way?

No, because you're still using the awful A/D converter in the iPod and going
through the existing headphone amp in there (which is a very high distortion
class D amp). You cannot expect linear electronics running on a single 5V
rail to be high performance.

Adding a headphone amp to the output doesn't solve any of the real problems,
it just adds more stuff when what you need to be doing for better sound is
taking stuff away.

And there's something in there (psu buck-boosting ?) that puts a 15KHz
noise on the input. Other than that Signal Scope Pro is great to have !
