I'm very interested to, they are doing a presentation of a Zen Mini, Zen and Zenith Server at the Bristol show in February, here in the UK. Hopefully they will be side by side, playing through headphones. I am attending and will report back.
I like the idea of including a CD slot for direct ripping and that they offer HDD, or SDS storage. The latter pretty much doubles the price, so I would like to go for the cheaper HDD version. That is why a demo comparing the two, would be very useful.
As you may know, the magazine HIFi Plus in the UK, really liked the Zenith and made it the Streaming/Server, product of the year in 2016. Yes, I know it's a commercial magazine, but it's the only one I have any confidence tin, at all.
Another plus for me, is that it is said to be easy to use, a big plus for me. It supports some Internet Radio and Tidal, not, QuBuz
