At 40 hours now. Sound definitely improved after about 30 hours (overnight), and it's JUST STUNNING now. It is really VERY hard to believe that the source of the sound I am getting is still an iPod. I have had a 4G iMod iPod for well over a year, and as impressive as it is, the 5.5g iMod with the VCap dock is really shockingly good sounding. No question it sounds easily, noticeably better than either of my $1500 digital disc based players (when playing CDs). Granted, it's not that far below them in cost, but it's of course far more convenient
Compared to the normal iMod dock, the VCap is more transparent, has deeper AND tighter bass, has slightly more treble extension, slightly more lush mids, and a slightly wider soundstage. I went back and forth repeatedly, and these things are easy to detect.
Again, great work Ken.
