By itself, it's probably not accurate to call the PS Audio Memory Transport ($1695) a music server. Built around a Teac DVD ROM drive (though the unit is limited, at present, to music use with two-channel CDs) the Audio Transport can rip CDs at a variety of resolutions (including lossless compression). It has limited internal storage, however. Instead, it is designed to be connected via its Ethernet output and a home network (wired or wireless) to an external hard drive (or even solid-state flash drive) of the user's choice. The latter, which is often a noisy device, may be located in a remote location in the home, such as in a closet. (I don't know about you, but my closets have no AC outlets. But there are ways to fix that.)
