When I bought my Innuos Zen, I debated about whether I would use the server storage built-in. Now that I'm used to the Zen, I have integrated use of the CD ripping into my playlist construction. I didn't take on the task of ripping all my CDs to the Zen. Instead, I rip any CD I'm wanting to listen to into the Zen, which takes no more than five minutes and is incredibly smooth and simple. The sound of a WAV file from the Zen is better than listening from my CD player or the Qobuz stream, so I can integrate the WAV files along with Qobuz tracks to create whatever playlists I want. Once a favorite CD is ripped to the Zen, it's easier to access the tracks I want to play than it is to use my CD player. The Zen is designed not to use the hard drive during file playback, so no noise is added to the system when accessing files on the server.
Based on the reports of previous Roon and BluOS users, I'm confident that the Innuos software produces better sound quality. I think the new Innuos Sense control app is designed to run on a phone or tablet rather than a desktop computer. I am using it on an iPad, and it works great.
