From the seller

For sale is my first-generation Universal Audio Apollo x6 Thunderbolt audio interface purchased directly from Universal Audio and professionally modified in 2025 by Black Lion Audio with their Premium Analog Modification and XB Clock Modification. These upgrades are designed to improve the Apollo's analog signal path and clocking performance, making this a particularly compelling version of an already excellent recording interface. Black Lion Audio Modifications: Premium Analog Modification: Upgrades to the analog circuitry and signal path, designed to improve clarity, detail, and overall audio performance. XB Clock Modification: Upgraded internal clocking circuitry designed to improve clock stability and reduce jitter. Condition: The unit is in excellent overall condition, with only minor cosmetic markings on the top and bottom surfaces from being installed in a rack. These are purely cosmetic and do not affect functionality. This is a great opportunity to own a professionally upgraded Apollo x6 without the expense and turnaround time of having the modifications performed yourself. Please feel free to reach out with any questions. Thanks for looking!
