I had a different experience with jplay than what they say on their info sheet. Jplay showed the progress of each track, which meant it must have been "in touch" with the streamer. Anyway, Jplay isn't working for me now. It won't connect with my Meitner. When I receive the MA3i and burn it in, then I'll start playing around with apps.
Again, my bottom line question. (I think A/Bing fine tuning can be deceptive because you're listening so intensely, in a way you don't when you're simply listening to music.) Have your wife or a friend play either Jplay or mcontrol and see if you can hear the difference after leaving the room for 15 minutes. The difference might be so subtle that you'll have no idea.
This is the experience I've had with changing speaker wire and interconnects. I can hear the difference when I'm concentrating on nothing else. But in real life, I'd never notice which cables were in my system.
