It sounds like he stores a "primary" copy of the music on his computer, so I'd definitely just look for a good DAC he can connect to that, ideally via USB. Think Cambridge, MHDT, Wavelength, etc. Connectivity directly to the IPOD is just too limiting, at this point.
Economical alternative to Wadia ipod dock?
I'm helping my 20-something son put together a system. He knows digital; I know analog...kind of. He currently stores the majority of his music on an ipod. What docking mechanism for the ipod would you recommend to feed into a DAC for a best-musical-experience for the buck? From what I can tell the choices out there are the Wadia 170i and ?. Thanks in advance for any ideas you can give me.
