Well for the budget I had I can't complain really. I usually end up
listening to music from my PC (mp3) these days and the Grado's with a
M-Audio 2496 are a million miles better than the Creative Audigy /
Plantronics rubbish I had before

How are you driving those Grados with that AP2496?

IME the AP2496 is not really designed to drive low impedance headphones like
Grados. It can work, but there might be some audible frequency response
variations due to the impedance curve of the headphones interacting with
relatively high output impedance of the AP2496. I'm not saying that the
output impedance of the AP2496 is high for a quality audio interface, I'm
saying its high for a headphone amplifier.
