QSA Stones

I have had 6 QSA Stones on top of my power conditioner (2 each of red blue and clear) for about three months, and have really enjoyed what they bring to my system. This week, I got another set of 6.


One thing I have learned over many years in this hobby is the importance of power supplies, and the impact they have on the sound of individual components and systems. A number of audiophiles with DIY skills upgrade the power supplies on components with bigger and/or better capacitors, and in various other ways. Unfortunately, I lack the skills to do this.


I ended up placing the new stones on top of the power supplies of my CD transport and amp (1 red, blue and clear on each). To me the very positive results sound similar to upgrading the power supplies, without all the hassle of soldering etc. Particularly with my amp, there was an increased sense of ease and musical flow, along with more solidity and authority.


I don’t claim to have any real explanation as to how the QSA stones work, but it seems to have something to do with their interaction with electromagnetic fields, such as those around power transformers. Fortunately, I don’t need an explanation to enjoy the results🙂


If you think this is all bunk, or can’t see how these type of things can have any impact on the sound, that’s fine, but I’ll politely ask you to refrain from making repeated posts to that effect. The QSA Stones are obviously not for you, nor is this thread directed towards you.

Ya snake oilers called me in yet again, 16th time

YOU HAVE TO BE "STONE" CRAZY IF YOU THINK A "0.1oz $86" PINK ROCK PLACED ON YOUR AMP IS GOING TO EFFECT THE SOUND😜

Can someone with a little technical knowledge let me know what kind of rock (the actual mineral) this item is?  I have tried several different types of rocks this morning on my components and have seen zero results.  If there is a claim that a rock can improve sound, my friend who is a geology nut will help me test the correct ones.  Also, the brick and the charcoal was a total failure.

Thanks for the Link George. Upon further study I note that the seller of these items take careful care not to claim they actually work. They use the phrase "These seem to ....." twice, and the phrase "these reach the upper mids".....which of course is a meaningless statement. A rock can not "reach" anything.  Legally, if they actually worked, the statement would read "These Do X,Y,Z." not "These Seem to Do X,Y,Z". This keeps them from legal exposure for running a scam. It also keeps them from being shut down by their local regulatory body. It is sad that these types of people do this....imagine some poor guy on fixed income being told,..."just buy more rocks and it will sound amazing."

Please cancel my request for the technical information.....however If someone would be specific as to the mineral needed, I will gladly audition the rock. I just tried a bocce ball and it did not do anything either.
