Zero distortion is not a tuning problem, it is a physics problem

The phrase "zero distortion" is used far too freely in the audio industry. The usual fate of an adjective that cannot be falsified is to be treated as a slogan — or, worse, as a tuning target: if sounding "cleaner" is better, then simply flatten the curve in the DSP.

But if genuine zero distortion exists, it has to exist at the level of physics. First, any form of compensation introduces its own phase and latency error — active phase correction sounds more "accurate" only because it relocates the error somewhere less controllable. Second, active correction presupposes a trustworthy reference, and where that reference comes from remains a problem.

BitDiamond takes a third route: do not correct, eliminate. Remove the permanent-magnet gap, levitate the voice coil actively, make the rear chamber acoustically transparent — no step introduces a new compensation chain, each one simply takes an error source out of the system.

This is not a claim that compensation is useless. The CIM compute-in-memory design holds inference latency under 45 μs, and the VWDF-MLP weight modelling algorithm allocates bandwidth dynamically according to programme content — both are valuable. The difference is that these algorithms are responsible for allocation, not correction. Getting allocation wrong is a design problem; getting correction wrong is a problem of concealment.
