Frequently Asked Questions

Which connector configuration should I choose?
Match the connectors to your device and computer — USB-C > C for a modern DAC connecting to a USB-C computer port, USB-C > A for a USB-C DAC to a standard USB-A port, USB-A > B for the classic USB Type-B connection, or USB-A > Micro B 2.0 for devices using a Micro-USB port. Contact Vinyl Sound if you're not sure which one your device needs.

How does Diamond compare to Carbon?
Diamond upgrades from Carbon's 5% Silver-Plated Long-Grain Copper (LGC) to Solid Perfect-Surface Silver (PSS), AudioQuest's flagship conductor metal, while keeping the same Carbon-Based Noise-Dissipation. Contact Vinyl Sound for a detailed comparison.
