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,

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,

If the HAP-Z rips SACDs as high rez that would be very big news. My understanding is that Sony has long held a strong position against the idea of ripping SACDs because of their interest in the sale of SACDs with their music biz. 
For many years the only way that anyone(and a small number) ripped SACD in high rez is by hacking a Sony Playstation of a certain vintage and doing some tweaking of the files. This is well documented online. Recently a similar routing to rip SACDs from Oppo players has gained popularity. You can find details on CA etc.
Contrary to @dbphd 's experience, IMHE it would be erroneous to conclude that ripped redbook layer from dual layer SACDs sound like SACD. Ripped SACD ISOs converted to 24/88 or 24/176 often sound like SACD, but occasionally get screwed up during the conversion process depending on the software used and settings (For me it's sometimes confusing!).
Many players show on their digital display during playback if the current song is SACD, HDCD etc. Does the HAP do that? If so at least it would be easy to confirm what the playback is looking at, 16/44, SACD or something else. Cheers,
