Maybe they got the RCA part right but made a mistake on the non-existing XLR part? Hard to know now if the whole thing was not a mistake. Probably some other edition has a footnote correcting the values, but who knows where and where.
A shame the Canton itself does not provide measurements to begin with, but unfortunately this is the rule in the market. We are spoiled having the detailed measurements from Amir and others of items reviewed here in ASR, and a few Chinese companies that publish detailed measurements, but they are the exception...
To be honest I am almost pulling the trigger in such a unit if I had more confidence in measurements and real world usage (free of issues, etc). Canton should really loan more units out for review. I think they are a German company mostly selling to German market, but when there is almost no competition worldwide for such a product (small affordable AVP) they are missing out promoting it imo.
