Topping Releases New Firmware V1.24 For D90 MQA DAC.
As with many DACs out there, particularly brand-new ones using AKM's latest AK4499EQ DAC chip, there is always the likelihood of adding minor improvements and fixing little glitches via a firmware update. In the case of the D90 MQA, Topping went ahead and issued firmware update V1.24, which addresses small issues for USB input users, allowing a new bit-depth for MQA users along the way.
It appears that Topping's engineers have been working hard on fixing the few bugs D90 users brought to the surface, and have therefore issued firmware V1.24 for the D90 DAC to address a few issues.
Topping D90 MQA DAC Firmware V1.24 Changelog:
Topping has declared that firmware V1.24 includes the following changes:
