My server/streamer is an Antipodes DX. When I was looking for a server last year I considered a few and choose the DX because of what I considered to be its superior SQ especially compared to others including the Auralic Aries. When the Aries was released it was a no for me as there was no Android App at the time. I do not know what the situation is now. I still listened to the Aries and was not impressed compared the DX. I had a bit of a gulp swallowing the price of the DX but I got over it.
The DX does what the posts above say about 2x DSD, acting as a bridge and Tidal etc. It has two USB only outs. One is powered and one is not. The DS works with both. It is wired network connected instead of wireless. It is an all metal case. It rips CDs to internal SSDs. This is considered to be superior for playback. As well it can play back from either USB drives or a NAS. These can be “mounted” on the DX. This means the DX sees the files on the USB drive or NAS as if they are in the DX. The individual files on my DX and NAS are interfiled into one file that I see on my tablet. I find it virtually impossible to tell the difference between the play back of a file on the DX vs a mounted one on the NAS. It is also easy to setup and operate
I have yet to compare playback from the DX mounted NAS file vs one from the NAS over the network into the DS bridge. I suspect that there may be a difference in favour of the mounted file. What will be more interesting is whether there is a difference with Bridge II. It may be in my case that Bridge II when it comes is superfluous for play back.
If quality is a priority I suggest that the DX is worth a definite listen whilst being more expensive that some other products. It proves the rule that what you pay for is what you get. The support from Antipodes over the internet is exemplary. I know I have something that is very very special connected to my DS.
