QSA Original Series USB Audio Enhancer/Adapters
Original Series = Full Bodied Naturalness
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.
Original Series
the Original Series has a touch of warmth, along with a wonderful, flowing naturalness. The Crystal series is the most neutral, focusing on transparency. The Horn Series has even the most 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.
