Splittie,
Are you specifically looking for a solution to connect an iPod to your system, or are you looking to improve the sound quality of the music collection you play from your laptop? Reading your original post it's difficult to determine which you need. You don't specificially mention connecting your iPod to your system, but you do mention the fact that your laptop is connected to your system.
So, do you want to improve the sound quality of digital music stored on your laptop, perhaps in iTunes, or do you really want to connect your iPod to your system?
