Best Dock , DAC

Mil - It is standard analog 2-2.5 VRMS, just like most DACs.

The real question is what kind of drive does it have. Undoubtedly an op-amp output stage at fairly high output impedance. Not great for a TVC....

Tm - the digital out sources from the iPod, but its through the special docking station that it is accessed. These stations usually have S/PDIF coax and Toslink outputs. There are 3-4 docking stations like this, including the Pure i20 and the Wadia 170. They also have remote controls with volume, but it is best to leave the volume at max on these and use either a DAC or preamp to control volume.

The ONLY way to do this and get great sound quality is using a digital dock, not using the analog outs from the iPod.

I second the Pure i20. I have one and its amazing for the price. The analog outs from it are fantastic,but can be bettered by taking the digital out and reclocking with a Synchro-Mesh. Then drive to a good DAC like a Metrum Octave or maybe the new Mytek. Total outlay about $1700 including S/SDIF coax cable and even less if you buy the DAC used.
