How much are you willing to spend for what pieces? Server typically needs some kind of network player if you want it to be located other than in your "music room". Or you can output directly to a dac if they are in the same room. I've never compared the "sound quality" of various servers but I am very happy w my MusicVault server that uses squeezecenter to stream wirelessly to a modified Logitech Transporter. I then take the analog output of the transporter to my pre-amp. Other folks start w a server and network player but then take the digital output from the player to a standalone dac.
