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.

SIX out of the last 13 posts on the Recent page are by one person. He has nothing of value to say in any of those 6 posts. What he does have to say not only runs counter to the purpose of the discussion, it is derogatory and insulting as well. The overarching attitude is one of stubborn unyielding arrogance. Why oh why is this guy even allowed on the site?

You are right t_ramey he should be banned. Maybe if enough of us request he will be? Meantime please report his abusive posts as what they are: abusive of other members and off-topic. If he wants to start a discussion about snake oil and shills he is free to do so. If he keeps wrecking discussions imposing his unwanted opinions and insults on us we are equally free to report him and request that he be banned.

If people want to chime in and tell other people how thing "can’t" work, then why chime in at all? If you have an explanation WHY, then share it and move on.

The same goes for everyone else that chimes in to explain everyone else’s ignorance or usually just calls everyone a liar. Their opinions and 5 dollars will get you a cup of coffee.


As a matter of general principle, the onus is placed on the person making a claim that in fact the claim has merit and has general application. This is a positive claim.

Others may then show cause as to any reason they may have doubt about the positive claim. This rebuttal may question any number of substantive and material facts that the claimant may make in support of their claim. Should this raise any doubts, the person making the claim is free to clarify, or seek to provide further information.

This approach is somewhat different to any claims that any tweak does *not* work. This is the scenario in the provided quote (roughly - the issues there are perhaps inadvertently conflated if you have read this far) and is an entirely different matter, and as some may know, it is tricky to prove a negative..

Unless you bring common sense into it.
