I have a set of QSA Crystal Violet USB adapters. If your streaming audio system sounds harsh, flat or fatiguing, the QSA Crystal Violet USB adapters will fix those issues. Adding more dimensionality and naturalness to the sonic presentation.
Where these differ from the Violet adapters is the Crystal Violet has a small amount more sparkle, air and space in the presentation.
These adapters are directional and meant to go on either end of the USB cable. I do not recommend using the adapters with heavy or inflexible USB cables.
