Thanks! Im actually satisfied now with the source. Only thing I miss is the spotify/tidal connect on it.Just a few notes and suggestions for you...
The optibox has an included "cell phone-like" power unit included with the NEO Stream. I myself have found no current benefit to upgrading that particular power supply, I am looking at it carefully.
In your case with already having the equipment you have the ZS would be the better choice for you, but keep this in mind, there have been many instances of DDC's either not playing well with the ZS, I have a Singxer and the only issue I have is I must set the ZS to Hardware volume, and not to "None" or my volume level is cut in half. Others have reported that using Spdif out to Audio GD Digital Interface causes a noise when no music is playing (this can be found in the Audio GD DI20 thread).
In a personal observation I do not notice any great difference when running my ZS to any of my DDCs, or better yet, I do not perceive any "greater" sound quality by doing this. I feel more is gained by using a DDC with a direct connection from the source (USB from PC/Mac to DDC).
I would definitely purchase from someplace that gives you a "no questions asked return policy" with a big enough playtime window, so you can judge for yourself!
Cheers!!
Hmm just found out Plex supports it and there is an app for it…interesting!
