The Grand Reference USB cable is a great improvement over my existing Audioquest Carbon cable. This cable manages to do surprising things for digital music. I know the difference between brighter sound and more detailed sound. The Grand Reference USB has a more detailed sound. I can hear this in both voices and instruments. Another surprise is that I finally understand what other people mean by holographic sound. It's a point when you feel immersed in the music as if it were playing around you. Everything feels large in height and depth with great separation too.

Thanks for creating such a great product!

Got the cable today and it works/sounds great! I built a shelf to get the computer in the basement up to ceiling just below the first floor.

Your cables have made a big improvement on the overall sound and a huge improvement on the low end.

Solid Core: Using solid core wire removes the stranding distortion found in stranded wire designs. This eliminates the smearing effect, allowing much more information to pass through.

Small Gauge: Using a proprietary small gauge wire removes the skin effect distortions that are unavoidable in larger gauge construction. You will hear things in your music that you never heard before.

Individually Insulated: Insulating each strand of wire individually allows the signal to flow unhindered instead of jumping from strand to strand. Great detail in your music is achieved. The emotion of the music comes through.
