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.

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.
