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.

Anyone selling a reputable product will have a full money back guarantee or even a trial period. Please let me know the details.

No no no don’t think this way, as if only half are sent back, these shysters, are still making a small fortune.
And the chances of you sending them back and not feeling embarrassed about the purchase, you’ll just throw them away instead, and say never again.

@oldhvymec. Funny thing is I have tried all this stuff, Shitaki Stones, Petoskey Stones, Tuning Sticks, Crystals and none if it did anything, Did not even make my wallet lighter as I sent all the crap back and only bought this stuff from vendors with return privileges.

Here is the other thing I do not see this stuff being sold the real high end audio dealers...





Those of you taking pot shots at geoffkait, here is his partial resume.

Geoff Kait -- Aerospace Engineering (theoretical fluid dynamics and propulsion, statistical thermodynamics, nuclear physics, indeterminate structures). Undergrad thesis: Preliminary design of low-thrust engine for interplanetary travel utilizing momentum transfer mechanisms in highly magnetic metal crystal bombarded by high-energy ions. Work experience: satellite operations; radar data analysis; aerodynamics of high-performance aircraft; reentry vehicle dynamics; radio communications; satellite communications; spread spectrum communications.

Rock on boys, ha ha, I made a funny.  


All these "snake oil" products need to be eradicated, from forums, where they get free exposure and get massive profits, without posting themselves if you notice, they just let their shillers do it for them. That way there’s no liability back to them for any claims on what they do.
