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.

you might try the stones in the main circuit box as the power enters from the street.

Throw them in the hydro water dam that generates your ac juice at the start.

Everybody must get stones.

Seriously,
Have any of you stoners tried an ordinary stone from your yard or from a mountain trip? Why wouldn't they have similar effects? Is it the paint? Have you cut open a stone to see what's inside? I can't believe I am asking such hard questions, seriously. 
Isn't there a song titled "I gave my sweetheart a cherry, she gave me a stone."
Not sure what that means, but it has to relate somehow.

Man you’ve got to have stones to even Suggest and admit to trying that sort of utter bunk. Glue them to cable elevators but make sure they’re pure porcelain and white. Next it will be a variety of pies in aluminum plates starting with cherry because of the possibility of stones in red goop…..

I did one search of the name, and it appeared to be a round black polished stone with a logo, but interestingly, there seemed to be a red faceted round stone turned upside down on its table glued to the front. Do they all have that? Is that glass, or synthetic corundum?
