None of the NG machines come with a cd drive built in. You can easily add one to one of the USB ports in the back. I have ripped most of my music on CD already — so ripping isn’t a high priority for me. I did buy a cheap LG dvd ripper (model number GP65NS60) that I used to rerip a couple of cds and it worked fine. Follow the directions on Innuos’ website to get it set up — very easy.
You can configure the Zenith NG with built in SSD storage from Innuos or you can add it yourself later. I got a 4TB drive pre-installed — more space than I’ll ever likely need, but it’s also easy to add a second drive if you want. I had used a separate music server with the Pulsar and wanted to eliminate one box by combining the server/streaming function into a single box.
So, I both stream Tidal/Qobuz and play locally stored music through the Zenith. No real differences in Sense 3 between the Zenith and the Pulsar in terms of functionality as far as I know other than the lack of ability to have internal music storage on the Pulsar.
No demo for me. I did buy from a place I could have returned it, but I wasn’t expecting that to be the case. I’ve been using Innuos machines for close to 10 years and each time I’ve upgraded I got better sound and good functionality. And this is again the case with the Zenith NG.
Hope this helps
