No one can tell you what's the perfect place to put these, it's a tweak product like isolation feet, roller blocks and dampers. All effect the sound. There will be people that love them, some will hate them. Some will say they do nothing at all. If you read the instructions and experiment, you can determine for yourself.

I've experimented with these a lot, owned eight at one time. It would require a phone conversation to begin to cover it all.

Pbb, you were NOT supposed to reveal that Herbert could not hear the stones. Yes, that is why he is no longer with us. Unknown to many, his pianist used the stones just above the keys near the sheet music stand. Until then the highs were never right.

I assume you use these everywhere? If so, you are ahead of me. I no longer own any.
