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.

"in spite of the fact no one has a very good explanation of how they work"

You said it Miller.  Except no-one has any explanation WHATEVER.

Except me.  The impression that a passive lumps of **** can have any effect on system sound is caused by psychological and mood changes in the listener and mistaken post purchase sub-conscious need for gratification.

OK. OK.  You believers go on wasting your money, why should I care.

And by the way, Miller, don't badmouth my system.  You have no idea what it is, except I have posted it contains the greatest power packing amps of them all: the Krell Reference KRS200, uprated to 400w.  Don't make em like that any more, the green madmen don't allow it.  That's why in power amps vintage kit rules more and more.  Soon we will all have to have wimpy Class D by law and some will continue pretending it can do a Class A job.

Ho hum.
