I'm using a 1 terrabyte Time Capsule as an NAS. I have my home's first floor computers (including my wife's business machine) hardwired to the TC. My son's computer on the second floor access is wireless. I'm running a MacMini with a van de Hull Toslink cable to my DAC, & from there to my tube preamp and tube amp. I use iTunes for playback, and have all my music files in Lossless format. As for why I like it, foremost it's a Mac like the rest of our hardware, so setup,& interfacing with it is easy. The TC also automatically backs up the hardwired machines on the network. Thumbs up!
