iPod as high quality hifi source?
I find myself downloading more and more music. Because of this, the iPod is fast becoming the main source for my system. I currently run a Marantz IS201 iPod dock, with Merlin Chopin interconnect, into a NAD C160 pre amp. The sound quality of the downloaded files (typically at 320kbps) seems good - they sound relatively uncompressed. When the 60Gb iPod is played through the dock as a hifi source, it sounds surprisingly detailed and musical. However, play the same piece of music on the Naim CD5 and you realise the docked iPod lacks the precision and space of the CD player. Compare it to the record deck and you realise it lacks the depth of soundstage and musical feel. I'm sure that I can do better. An obvious choice seems to be the Arcam r-Dock (with a high quality cable), but how much better sounding than the Marantz is it? The Advance Acoustic MIP Station 2 also looks very interesting, with an impressive specification and good value, but there seem to be no reviews rating sound quality. Are there any other docks out there that really allow the iPod to perform as a high end source? i'm after the best sound I can achieve from the iPod, on a sensible budget - any ideas?
