I have iTunes on my laptop, a Dell Inspiron 14. Wanting to listen to music from this library through my home theatre speakers,, I connected the computer to my home theatre's pre/pro via the mini headphone output jack on the computer to RCA inputs on the pre/pro.. It sounded real good, indistinguishable, for the most part, from SACD; however, I did notice, occasionally, some dropouts. Now I send USB from the computer to an X-FI HD where the digital signal is converted to S/PDIF, which is then sent to the pre/pro. And, since the pre/pro accepts a 24/96 signal, and the X-FI will pass through such bit rate, I allow the computer to up-sample all material in my iTunes library to 24/96. So far, all of my music, even the 256k files, sound indistinguishable from SACD in A/B comparisons. And, now, no dropouts like I had when I used the headphone out jack to my pre/pro. Since, I believe nothing sounds better than SACD, I am happy with iTunes as a media player, as virtually every thing I've stored in the iTunes library, from 256k downloads to 24/96 rips, sound, as earlier mentioned, like SACD.
