Axelwahl,
I have a 10" Continuum Copperhead and a 12" DaVinci Ref Grandezza mounted on my Raven AC-3 and I can hear no increased distortion on the Copperhead over the DaVinci on the same recordings.
I agree with Dan_ed that without correct alignment, the 12" arm will sound just as poorly as the shorter one without correct alignment.
