    Here is a document from 2013 on Cadmium.

    My personal choice is to avoid cadmium containing devices where there is a practical alternative, but everybody is free to make their own choices.

    as is the case with encapsulated types why deny yourself a better audio experience ? I think we are going round in circles.
    I would like to know what Colin has achieved,
