QSA Modified Crystal Gold Version Audiophile Network Switch

Full StarFull StarFull StarFull StarFull Star 
Like all QSA devices in my experience, the Crystal Gold Network Switch is superb. I've used, and owned, a number of network switches and it is supreme among them all. True, it's expensive; but the price is actually in keeping with its audio performance...it's simply that good. - John Z., Verified Buyer


QSA has performed another sonic miracle with their Crystal Gold 2.5 G network switch. If you've experienced The QSA Fuses, or AC adapters, The sonic effect of the switch is similar to the Silver and Gold level QSA products in terms of performance.

The Crystal Gold version has been treated with their proprietary processes, and materials. It appears to have more crystals used in treatment. The QSA Crystal Gold Switch adds one more process QSA calls DSRT (Digital Sound Removal Technology). The claim is removal of the unnatural sound that digital audio can so often impose on music when compared to analog sources.

You have 5 Ethernet ports, and it requires a 12V DC source. We recommend using a high quality linear power supply, as better power will allow the QSA switch to perform even better.

A Word on Break-In

The higher the performance QSA product, the longer the break in time. The QSA Switch is no different, and being the top tier QSA product, it will require 60+ days of break in time.
