What are the differences between A30.3 and A30.3 MK2?

Tuesday, October 13th, 2026 |

Imported from the Zendesk Help Center (created 2021-11-18).

The differences between the A30.3 and A30.3 MKII are predominantly running production changes, in part due to the longer product life span of Primare models. As such, the changes subtly effect long term reliability (capacitor change in the power supply) and a somewhat more open upper frequencies (as a result of resistor and capacitor change in output stage). In both cases either model should provide long life and excellent performance.
