The iPod can sound wonderful "if" you are using uncompressed (AIFF) or lossless (Apple Lossless) files, and use the digital output, which requires a product like the Wadia dock or Naim DAC. There are other products that allow this as well.
Make sure "SOUND CHECK" and "EQ" are turned off. These destroy the sound quality of an iPod.
If you need to use the analog output, get a dock connector that allows a true "line level" output. DO NOT use the headphone jack unless you are using headphones. As for headphones, I like the Etymotic HF2 headset or HF5 headphones. The HF2 just adds a mic and control for the iPhone/iPod Touch. A nice headphone amp will improve the quality if you want to dig deeper.
Tomorrow (September 1, 2010) Apple will introduce new iPods, so I recommend waiting to see what happens. My guess is that the "click wheel" will be going away. ;)
