I just ordered an Up2Stream Pro v3 with a case. As I look, since the spdif module is a separate panel that can be attached to a surface with two screws on the connector side (so it doesn’t fit on the main board, it connects to it via a cable) and the Arylic case is just two plexiglass sheets with screw spacers, so this case won’t keep the spdif module fixed (if I think so) …
I haven’t received the device yet (only the plexiglass sheet has arrived) and I haven’t asked for a spdif module either (in principle, the spdif is routed out of the bus connector, even without a separate panel). It can already be seen that the “housing” is actually a very simple structure, practically a plexiglass sheet at the bottom and top, fitted with four copper screw spacers. As soon as it arrives, i will try to send some photos (but it can also find a lot of pictures of this type on the net.)
First round: this is my third Arylic device (i have also an S50 Pro, and an Up2strem Amp 2.0), perhaps the best value for money model from them. Positive: takes up little space, stable connection via wifi (including multiroom), DIY expandable on request. Negative: “board model”, no standard RCA (balanced XLR anyway), obviously not intended for audiophile music listening.
There is an interesting forum with some Arylic device measurements:
…by the way, i think these cheap devices also have their advantages, but unfortunately the real sound experience has to be found in the more expensive systems, the big problem with the A50 (and the Up2strem Amps) is the cheap and poor quality D-class amplifier IC (and switching power supply), and the output of the S50 is 44.1kHz resampling.
