Prototype – Using the DB4.2 as a benchmark we designed a new model to incorporate the best quality IR2093 transistor platform with SMD technology.
V1 – Power ratings to remain similar to DB4.2 but audio quality will be significantly better than the DB4.2 to justify the higher price point of the 4.3. Was originally intended to be launched as bluetooth but we were unhappy with the software and so we deleted this from the specification until we can see revisions.
V1 – Production was initiated to a final design in Q3 2017 with first customer deliveries in early Q1 2018. The sonic performance of the DB4.3 exceeds expectations with musical performance that belies its class D architecture. Heat is well controlled and the high level inputs work very well indeed. Please note strange wiring of rear high level input, mentioned in instruction manual.
