Oh, definitely. It raises the CPU usage pretty drastically for all codecs.
Luckily for you, Musepack is, if I remember correctly, a very CPU friendly
codec on Ipods.

Nope, it comes from CPU usage, as you say. For example, for each band in
the software EQ you disable (set to 0 dB gain), the CPU gets a bit less to
do, so if you can use the HW EQ shelving filters and disable the software EQ
ones, you'll win a bit more CPU power back.
