Demo QSA Modified Crystal Gold Version Switch with Hapa Audio Linear Power Supply

 

We have for sale one of our demo QSA Crystal Gold treated switches. This one comes with a very special Hapa Audio linear power supply and DC cable. If you are familiar with QSA, you will be familiar with the sound that this imparts on the bits flowing through it. The background noise is lowered, there is an immense sense of naturalness, flow, air and space to the music. Low level information comes forward and is heard for the first time. A truly astonishing product!

The items are in 9/10 condition and work perfectly. There is a flight case for the power supply, and a small hard case for the switch that is included. Setup is plug and play, and we suggest using this as the switch that connects directly to your streamer.

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. For this we have the Hapa Audio 12V linear power supply with their Torsion OCC Silver DC Cable.
