Why is direct I2S connection better than s/pdif?
The msb ipod/ilink doesn't come with a DAC. So for the $2K, you could get a new apple laptop with iTunes that would serve the same function. I would use a Benchmark DAC/USB that has a direct I2S connection. The problem with the msb ipod/ilink is that it cannot be charged while in your lap with the plug-in RF remote transmitter and if plugged into the base station, it cannot sit on your lap. The computer on the other hand can be used for other tasks when not listening to music, can stay on the wall outlet, so no need to charge and if operated with a remote contro,l can be a music server from your listening chair.
I just need to find a remote control device for the MacBook to allow use of the iTunes interface from a distance.
