I love iPods, own three of them, but the idea of torturing an iPod by strapping it to an expensive external dock to create a truly high-end system seems like more of an interesting technical experiment than a reasonable way to spend money on good sound.
When you've gone to the trouble of bypassing the internal amp and the DAC of the iPod all that's left is a small hard drive and a very nice user interface, both of which you can get any number of other ways with greater capacity and for less money.
