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.

These things are just hand off from Geoff Kait’s Machina Dynamica Pebbles he was selling, at least your money stayed in the US with his snake oil.

I'll bite. I think its all horse sh*t. All of it. But do they have a money back guarantee? If so I could be persuaded to try it. I'm kind of a sucker for sub $100 tweaks.

Agreed.  Anyone selling a reputable product will have a full money back guarantee or even a trial period.  Please let me know the details.  I am unable to find a review posted at a reputable industry website...perhaps someone can post a link? 

These seem earily similar to the guy who used to sell "Brilliant Pebbles" and had pictures of taping them to your ICs. He also had a "Super Intelligent Chip" that you put on top of your cd player and somehow lazer light would leak into the room and activate the magic.

@millercarbon you are a Copper Bracelet Salesmen s dream.

So I have some Polished Stones my kids bought in Petoskey Mi when they were younger. I placed them on my X200, put on the copper bracelets I bought from the old woman in Cicero and put a tin foil hat on and guess what?
They're coming to take me away ho, ho. 

No really why do I need to disprove this nonsense when you can not back up your position with any data other than your wax filled ears.
Think about it even the FDA (I know touch subject) when getting approval for a drug you have to provide the SCIENTIFIC DATA that the drug will do what it is intended to remedy or cure.

So why do I have to disprove what you have no proof of?

Keep up the silliness.
