You wrote "Listening to my recordings allowed me to adjust the placement for less room echo...."
That's brilliant!
I just spent about 15 minutes moving my Echo around the kitchen, stopping at different locations to say "Alexa, here's in the middle of the kitchen table", "Alexa, here's near the kitchen window", etc.
After that I played back each recording and pinpointed the best place for voice reception, which also happened to be the best position for sound reproduction. There were a couple of locations where the playback was so poor, I was amazed Alexa was still able to transcribe what I said.
