QSA Power Conditioner - Red/Black

Plug & Play QSA

NOTE: Cardas and Oyaide plugs are INCOMPATIBLE  with QSA AC Jitter Adapters

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:

1. Half the price of the corresponding color QSA fuse
2. Very similar sonic effect as the QSA fuse
3. Will never blow like a fuse
4. Super easy installation. True plug and play
5. 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 almost immediately, and improve further over time. 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.

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. Initially they may sound great, or not. All have an initial glare that goes away over time.

Using Multiple QSA Power Conditioners:I used to think it was 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. This may not be optimal in every case. ALWAYS experiment with placement, as your mileage may vary.

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.

Passive Effect?

We have also discovered that plugging other AC adapters around your home grid actually improves the sound of your audio system. This particular case it is okay to use a lower level adapter, since it isn't directly in your system.
