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.

even more so than the fuse scam, which thank god is now under control.
Wow, a sigh of collective relief. Do you have some sales figures George? Has your tireless crusade finally made a dint into the ill gotten gains of those devious charlatans?

So  @millercarbon you are part of the cancel culture.

Deplorable.

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.

it is tricky to prove a negative..

Unless you bring common sense into it.




No, that is not sufficient. What this is perhaps suggesting is that certain facts may be taken as truth because they are so well known or authoritatively tested that there can be no doubt.

Even that can be tricky in a variety of circumstances. A trite but well known example - there was no evidence of black swans before about 1800. They were unicorns. Common sense said no way, dude. Yet today they are (relatively) well known.

Check out the Wiki entry on Orgone. Whilst the subject of justified mirth (in hindsight), nevertheless some very substantial claims were based on its existence.

Anyway, the notion of what constitutes common sense is not universal as between different cultures or other metrics of consciousness, so that’s another hurdle not considered in my first paragraph, and quite possibly more important in the circumstances.
