A: Technically yes, but not recommended. You would need an older .bin file and the same USB process. Downgrading may reintroduce bugs.

For the discerning audiophile, the Audiolab 6000A represents a sweet spot in high-fidelity integrated amplifiers. It combines the warmth of a Class A/B amplifier with modern digital connectivity, including a high-quality ESS Sabre32 DAC, Bluetooth aptX HD, and multiple digital inputs. However, like any modern piece of digital hardware, its performance and feature set are not static. They are dictated by firmware.
