Watching this with interest, the z9 mini is one loud machine so anything to make it quieter is a god send.
Try the S9... Z9 is a dream by comparison. ;-)

Saw your neat setup with the tent in another thread.
Wondering what noise level you get.
It's still loud, to be honest. ~80db outside of the tent. I figured 'sound isolation' would be another project at some point. The tent isolated it enough that they can't be heard throughout the house and no one flips out if I leave the door to that room open.
It's loud enough that i can't use open ear headphones in that room.. and closed ear is questionable. :/
