I disagree with this. Computers make terrible music servers. They have mechanical noisy fans, electrical noisy power supplies, and spinning vibration inducing hard drives. Everything needed to conspire against quality sound reproduction. Use a computer for computing, and background listening, and a dedicated music server for serious sound.
The way hi-rez audio is today, it amounts to a hundred different trial balloons to see what sticks. When they come out with one device or one computer that is built for good audio, is easy to use, and comes with software designed for good audio, at a reasonable price, then it will take off. Just too many different ways to screw stuff up or this not working with that....blah blah.
Some would say a higher end music server is such a device, but not really. While built for audio, your unable to add software to it like a computer. If they could take a good music server and incorporate that into a computer as an all in one with out compatibility issues, they'd have a seller.
