Apple recently debuted a Mastered for iTunes section in the iTunes Store, where audiophiles can discover releases that have been optimized for playback within its 256 kbps AAC format. Chris Foresman at Ars Technica delves into what goes into the mastering process for compressed digital audio files, including a discussion with Masterdisk Chief Engineer Andy VanDette (who recently completed a remastering project for Rush’s back catalogue). follow link
Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.

Mastering the Audiophile Experience for iTunes
Contrary to what the referenced article says, audiophile reproduction does not require expensive or exotic equipment.

Keep that in mind and you can do well.
