Hi Mapman, you point out the potential problem exactly... While I evaluate the audible performance of a device purely on the merits of, well... Its audible performance, there are a number of components to any of my published scribblings.... And one of the components is an -- as musch as possible thorough -- ddescription of internals, based on my own informal transcription of my recorded discussion of published/publishable technical features, that I have had with the primary source... Usually this being the designer or the manufacturer.
I disregard completely any third party information that I am not able to confirm/corroborate from an open and willing primary source... Hence, third party reports of internal features are cheerily ignored... Nor do I go spelunking inside a component without written authorization by the manufacturer.
In general, doing a review of a mystery box is something that would leave me a little disconcerted. G.
