I am trawling the web trying to find information on iPod docks that I can connect via RCAs to my Integrated valve amp. It seems to me that there is no information that clearly confirms that what these docks are doing is taking digital signal from ipod and using their own da converters before sending out analog signal. If these docks are using the iPod da converters isn't this defeating the purpose a bit. I have looked at pro ject, wadia and denon. Even the wadia, which appears to be the most acclaimed,is really only a digital conduit, that takes digital data to your amplifier which then must do the da conversion. Please, does anyone know of a dock that does a quality da conversion? Thanks
