Ozpeter, Thank you.
You have written very well and beautifully.
The internal microphones A10 may not be perfect, but they convey the sound very realistically. I discovered this when I played with him for the first time at the table at home, something was noisy outside the window, the computer played music, something rattled in the kitchen, something was said by a girl passing by ... when I listened to the recording after, I always wanted to turn around or reply.
What the A10 needs is a 10-20 dB attenuator. for some situations.
