I use a mac, as it's output is bit perfect 'out of the box' , I use a firewire dac , just plug it in, and an ipod 'touch' as remote control, you set the mac up to automatically rip and eject your discs, choose AIFF or apple lossless, the mac fetches the album art work, and the itunes interface is imho unbeatable.
You can play everything up to 24/192.
Sound quality is equal ( some say better ) to a cd transport through the same dac.
