I can't understand why every manufacturer offers an iPod dock. If I buy a highend audio system I shouldn't even think of "MP3" especialy MP3 & iPod as the iPod is the cheapest sounding player compared to the Sony NWZ Walkman series and Cowons S9 etc.
An ipod supports apple lossless format and can provide a digital output. Plug that into a high-end dock with a quality D/A (for examples see http://www.hemagazine.com/node/High_End_iPod_Dock_Roundup), and you've got something similar to a BS5 for ~1/5th the cost... better yet, you can easily step into this as many already have all their music on their ipods. Pretty compelling when it seems that 90% of the world has joined the "ipod nation". Not me, though, I'm still holding out with my BS2, and very recently a BS5... but I can definitely appreciate the popularity of the ipod (the rest of my family has ipods) and the desire to get a cut of that action.
