I saw the Wadia at the AKFest in May. It's the real deal. I believe it is the only iPod dock on the market that takes a digital signal directly off of the iPod without the need to mod/deface the iPod. If you rip your music to iTunes in a lossless format and then sync it to your iPod, it should be comparable to a good CD transport or hard drive based system.
If I were in the market for an iPod dock I would definately buy the Wadia.....
Enjoy,
