I have used a Music Vault for about 10 years. They can address pretty much all of your needs. Not sure if they can rip DVD-Audio (I should find out, I have a few). They have RAID auto-duplication w up to 8 TB local storage. They can handle DSD files files. Two of the best features are the Logmein software that allows Neal to troubleshoot remotely, and the Solid State HD for the OS, which makes it boot fast and maximizes storage. No idea of how it compares to the Lampizator but I love the sound. I used to serve the files wirelessly to a Modwright Transporter but now I have it hard-wired to an Antelope Zodiac DAC. It can also provide analog out on RCA or AES/EBU jacks.
Give Neal a call; he's very approachable and responsive.
