I bit. Four cheap ones are coming to try. If they fail in audio
but make my wife sleep better it's still a win. I have a high confidence
level though, based only on those who have actually heard them in use. $45 del'd/4 so no worries on my
end if no results. If one or two are enough I have spares. I remain open-minded on this.
Thanks to all who have tried them and reported back, favorably or not. Their information is of value. As for the rest (with lots of opinions and facts or non-facts), I'm unsure what dog you have in this fight over whether they work. Seems you won't know either way if you don't ever hear one. And we sure have worn out the track with repeated laps...
I am interested if anyone has any experience with the SRs that generate a square wave versus a sine wave. I am wondering about the possible differences between the two based on some comments on 'pain' with square wave resonators. Thoughts based on real experiences are what I'm interested in. Possibly educated theories could apply. Thanks much!
