FW version 4.11 (04.18.2024)

– Fix: removed red status led inside chassis flashing on volume change. Otherwise, all is the same as 4.10.

FW version 4.10 (04.04.2024)

– Redesigned volume control, now featuring a snappier, less laggy feel and better overall dynamics and distribution.
-Disabled the “Volume Limiter” setting while using headphones.
-General code maintenance.

FW version 4 (20.09.2023)

– Added a ‘tube flash’ to standby/off command while volume button winds down.
– Added commands and compatibility with new remote model. See remote PDF manual here. (All basic commands are compatible with legacy remotes).
– Fixed “volume bump” bug on upper volume ranges.
– Enhancement of remote operation and volume response curve in the high extremes. Your usual listening volume position will probably shift upwards, but overall amplification is the same.

FW version 3.03

– Added a ‘tube wink’ confirmation to standby/off command.
– Enhancement of the volume response curve: lower minimum volume; greater range of control, especially in the low and high extremes. Your usual listening volume position will probably shift upwards, but overall amplification is the same.
– Debug of the remote volume command: the volume and hold command direction would mix in some instances.
