Challenges and Creativity – The AX4B-533 Tube Motherboard
The challenges that AOpen engineers have encountered in this endeavor are many-fold in terms of
providing a faithful music reproduction scheme to be combined with the motherboard – commonly referred to
as “On-board”. Our engineers have remained undaunted by those challenges. The design of such a novel
concept involves not only digital know-how, but also linear electronics and acoustic know-how. Musical
aesthetics also play a big role, right from the concept stage, all the way to the testing of such a unique creation.
Meeting the criteria of so many existing playback environments is also a consideration that AOpen engineers
have taken into serious account.
