already have old dell desktop with itunes on it feeding my 2 channel / multi-channel system . Usb out thru some external 24/96 card (soundblaster? ) digital out is digital coax into a cambridge 840 Azur (used as a DAC ) output to ARC LS - 7 or Intregra 7.8 . Used lossess settings in itunes . Went to itunes after i touch purchase,originaly ripped with Media player in lossless,then converted to itunes.Also have this in both formats on a seagate 1.5 t external HD. Now I am wondering if I should do something different with my new laptop maybe No itunes . Laptop has digital SDIF output. I like the eye candy of i tunes & the convenience of getting album art ,tho I don't buy their lossy music. the Azur 849 has upsampling 24/384 so do I need some other upsampling software?Foobar? Monkey ??? Kernels? I'm Sorta got information Overload.but I will get it ,maybe ....HELP
