Importing files to iMac

Don't rip with iTunes. Download free XLD for mac. It will get you bit perfect rips into AIFF with greater accuracy than iTunes. Use error correction option. For really scratched discs use 1x or 2x speed; it will usually still work, just a bit slower. After each rip it will create a log that confirms details of the results. Scroll all the way to bottom and usually you will see "No errors". Cheers,

@sbank , I've used XLD on my Mac and it works very well. I forget, doesn't it save ripped tracks into the iTunes library?

It does.

It saves ripped tracks wherever you specify. Could be your iTunes library if you want it to be, but it could be a different folder if you prefer. Cheers,

Following advice of Abe Collins at an Asylum thread I reset iTunes AIFF encoding to automatic and 16 bits.  I've now become pretty proficient at resetting the Sony HAP, clearing the iTunes library, resetting encoding, and clearing the memory of the HAP transfer app.  The actual process of ripping to the Sony HAP-Z1ES requires of me only inserting a CD or SACD into the reader I use with my iMac.  The resulting sound is excellent, indistinguishable from that with the disc played on the Sony SCD XA5400ES.
