Good question re loudness, mine is on 1 and still louder than any other machine I have. Obviously I don't want it on zero.
An important question given our bedroom is above the pins room and I like to keep the wife happy...
And re earlier requests on whether to get pdi or invisiglass glass, I actually thought I had pdi glass installed, it's so clear and beautiful on my AFMrLE. Certainly no great loss in clarity on the invisiglass on the WOZ and Hobbit next to it
