QSA USB Audio Enhancer/Adapters - Crystal Series


Crystal Series = Neutral Clarity



What They are


The QSA USB Audio Enhnancer/Adapters are designed to enhance the audio of your streaming digital system. They incorporate the same metallurgical treatment that makes the other QSA products so remarkable in what they do for sonics. They don't look like much, but in this case looks are very deceiving.


What You Get


The 2 piece set of adapters consists of one USB A-Type adapter for your streamer or laptop's USB output, and one USB Type-B adapter for the connection from the USB cable to your DAC's USB input.


Crystal Series


The Crystal Series emphasizes transparency over all else. Whereas the Original Series has a touch of warmth and adds a natural flow to the music, and the Horn Series has even more warmth with emphasis on a lush and present midrange.


Their Effectiveness


Even on our extremely tweaked out streaming setup, which consists of the following:

We immediately heard the effect of the adapters. Immediately, there was more musical information, and it was presented in a very natural, organic way. This was straight out of the box!


A word on Break in


The QSA products take longer than normal to break in. We recommend 30 days of continuous use. For Silver and Gold level devices, break in can be double that.


Our Guarantee


We guarantee you will love the QSA USB Adapters, or you can return them for a refund of the purchase price. We extend this guarantee for 60 days up to Black/Red, and 90 days for Silver and Gold level adapters.
