Audirvana Plus also gets my vote for ease of use, and all round capability in playing every format (DSD ISO, DSF etc). It falls short of Amarra/PM's plug in/roomEQ capabilities but those I can live without. That said, I heard Audirvana Plus is going to get an upgrade to add those features. The programmer is prolific and highly responsive to bug fixes etc.
If you don't need DSD, I strongly recommend having a look at BitPerfect from the AppStore. So cheap but IMHO it works just as well with PCM files.
For ripping, I use XLD. It's Mac's equivalent of EAC on the PC. And it provides a good log of the ripping process.
And yes, Remote for the iPad/iPhone is free and works incredibly well. My only wishlist for it is to add "cache" for album covers cos it seems to reload the album covers quite frequently.
