first recording with the A10 last night. Loved it.

So easy to use and didn't notice any external interference. LOVED the app to adjust levels and start/stop recording.
Used Line-In from CA-9100
Agree about the app; love the fact that it's SO easy to use. My buddy doesn't see the point why I love it since it's not that hard to pull out an M10 and look but I love the fact that I'm simply "looking at my phone."
What kind of input level via Line-in did you use?
