"From a business standpoint I cannot understand why Apple themselves is not coming out with something."
You must be kidding - the market is tiny for the audiophile-quality sound that the Wadia can deliver when taking the digital signal from an IPod and feeding a decent DAC. Do you think IPod owners own the DAC's required to convert the signal? That's why the Wadia also features analog outs - Wadia hopes to sell a few of these things. The high-end two channel market is extremely small -- you can count on two hands the number of two-channel manufacturers that sell more than a $1 million of product per year (there are very few Krell, Audio Research and Sonus Faber's).
I bought the Wadia and run it through an old tubed DAC so my wife can listen to tunes in better than dogshit fashion when she is home.
