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.

ecpninja- Really love Miller carbons setup. Great looking room as well. Thanks. The system is in a room built 30 years ago, the culmination of a lifelong dream to have a dedicated listening room. There is so much nonsense around this I won't even go into except to note everything I am talking about is based on actual experience. So the room gets built and having drilled into me how important this is first thing when empty the floor is gridded out and I am trying all possible speaker locations. I mean literally gridded out, lines on the floor. Every speaker location I listen to music and also play test tones. Remember 30 years ago we don't just push a button, we have to actually try and learn and understand. By the way when I say all possible I mean all, including listening locations. Speakers go one spot, listen here, then 6" farther back, 6" farther, 6" more- move speakers, move chair, lather rinse repeat. Again, 30 years ago. Thanks to this exhaustive work I have enjoyed really excellent imaging right from Day One. JBL L7, Linaeum Model 10, Vandersteen something or other, Talon Khorus, Moab- if it ain't broke don't fix it. Acoustics went through the same process. When my turntable was built Steve Clarke took some pictures and they are a kind of snapshot of what things were like at that point in time. https://theanalogdept.com/c_miller.htm We had some guys over recently, Brandon was impressed with how smooth the response was but there is a peak that creates a bit of ringing and this is a good example of how none of this push a button stuff is necessary. I said yeah listen and clapped my hands. Flutter echo, ringing. Moved, clapped, no flutter echo no ringing. Could use some diffusers. You can figure out where just by clapping and listening. Don't cost nothin'. Works. I even know what I want them to look like. Just need to actually stop and build the damn things. |
