Took it out for it's first run on Sat. at Bryan Adams from 22nd row center outdoor amp 4023 > D10. My only observations so far are :
1. Like the A10, it's nice to stealth without ever having to take the recorder out because you can stop/start and monitor with bluetooth and the iphone.
2. However, the A10 lets you adjust levels on the iphone app, the D10 doesn't. For this I could still easily find the level knobs on the deck under my shirt.
3. When you engage the hold button, the backlight turns on. I didn't notice this until after the show ended, luckily none of my neighbors saw this (or maybe they didn't point it out to me).
4. Running on 4 AA Maha 2700 Nimhs. After 2 hours running 48V phantom it was still at full bars.
I'll have a sample up later today.
