I recommend against it. I did own one for a few years (2011-2014 or so; 2tb hdd).
As a cd ripper, it’s overpriced given that you can rip cd’s for free on any computer you already own that has a cd drive. And if your own computer doesn’t have a cd drive, an external one is very inexpensive.
As a cd ripper, it uses a Naim proprietary format for metadata that makes the default rips neigh unusable outside of the UServe. While you can set it up to rip to flac instead, even then the metadata it adds is very rudimentary. Better results with ripping cd’s on a computer.
While I cannot determine its statistical reliability, mine did need to go to service once during its lifetime.
As a player using its BNC output into a dac V1, it’s a good quality player. But not exceptional or better than other options. (Do you already own the dac V1?)
If you opt for the SSD version, and end up having to use a nas for storage of files anyway, you’re 90% there to just using a Nas with a home computer to rip and the UServe being redundant (if you want to use the nas as a server; a nas directly into the V1 will not be satisfying).
