QSA Power Conditioner - Yellow
Plug & Play QSA
Our Report: This Is The Unicorn of Tweeks
It took about 30 seconds for me to figure out that these may be the best tweak ever. The QSA fuses set the bar really high, but these have surpassed them in my opinion. You have the effect of the fuses, more low level detail, better phase detail which encompasses a whole host of sonic effects like: more low level information, better and more separate harmonics, complicated musical passages rendered with more intelligibility. Plus improved bass detail and slam, and finally an over all sense of ease and naturalness even at high listening levels. To me, and in my experience, this device is the ultimate tweak for the following reasons:
- Half the price of the corresponding color QSA fuse
- Very similar sonic effect as the QSA fuse
- Will never blow like a fuse
- Super easy installation. True plug and play
- Will not void manufacturer warranties
For these reasons I feel the QSA Power Conditioners are the ultimate tweak.
The QSA power conditioner works very simply. Plug your power cord into the QSA power conditioner, then plug the conditioner into the wall, or another power conditioner. The effects will make themselves very apparent after a day or two (longer for the higher level models. Sorry!). More inner detail, PRAT, and simply a more natural character to the music. For those of you who have tried the QSA fuses you understand. Also understand that these behave more like the fuses than the QSA Outlets do (I have no idea why, but they do). The effect is additive as well. We have seen no downside to adding the QSA Power conditioner to QSA outlets, and products that already have QSA fuses inside.
For those of you who have been curious about the QSA products, this is perfect, and simple. Much easier than replacing a fuse, and the benefit is extremely similar.
Our Experiences So Far
Break in: The higher the level (color wise) the longer the break in time. All will take at least 50 hours of break in. You don't need to be playing music through a component to break the adapter in. Just having the power on will do.
Using Multiple QSA Power Conditioners: It is best to buy one of the highest level that you can afford, plug it into the wall and have it power your power conditioner/distributor that powers the rest of your system. Do that instead of buying several lower level Conditioners and putting one on each individual cord.
If you are going to do multiple QSA Conditioners, for instance for your power conditioner, and all components plugged into said conditioner, buy the same color Conditioner. The only exception might be for a subwoofer. All other components responsible for passing a full range signal should have the same color of Conditioner. A lesser level Conditioner that follows a higher level will have inconsistent performance. For example: Having a Red/Black at the wall, powering your AC distributor, then adding a red to a component that is plugged in to that distributor, you might get a more liquid and expansive midrange, but the highs will be more recessed. Keeping all QSA Conditioners the same offers more predictable results.

Based on reviews to-date, I took the plunge and ordered one of these, which I have plugged into the power cord (using adapter to allow after-market 3-prong cord) feeding my M1 Mac Mini Roon core. It has now been plugged in for about a week, with the Mini powered on 24/7. I have to say I was a bit skeptical based on the appearance of the device, but wow; the improvement in sound quality in this location is not the least bit subtle. Everything is much “purer” sounding, for lack of a better word. Things just sound more natural and “real”, rather than like reproduced sound. I think I may need some more of these for my other components...
I have worked with the QSA Power Conditioner Yellow for a few days now. It has made a noticeable improvement in every situation I have tried it in so far. For my tube amp and my class D amps, I heard more resolution, a darker, cleaner silence between notes, and a wider soundstage. It even made the picture of my girlfriend's TV seem brighter, more contrasty (in a good way), and more 3 dimensional. Pick up an extra and carry it with you, it works in so many situations!
From hearing these Yellow plug-ins, this is definitely similar to the fuse at half the price, I bought 3 to try out with my integrated, DAC, and streamer and found myself listening to more music. With yellow, there’s more detail and more ease. Seems to lower the noise floor, so more treble information comes through.
