Another vote for Innuos. It is good value and easy to rip, a big plus over some more expensive competitors, such as Aurender. There seems no point using a Server, then adding a NAS, particularly if it doesn't
use SSD storage. So if you need 4 TB's , you have to suck up the price I'm afraid.
Whatever unit you buy, there will be a Mark 2 or super version out a month later, that's just life. I am still very happy with my Mark 1 Zenith and see no reason to change.
As a matter of interest Dave or Troy, do you have a favourite reasonably priced DAC to use with the Zenith. My ageing Ayre QB9 is very good, but getting temperamental. I was thing of the Chord Qutest, any other thoughts? Thanks
