I've 9" and 12" Jelco 850 arms on a well-fettled 401 so I can make direct comparisons. Bass is a little tighter and the overall sound slightly drier on the 9". The 12" has more authority, liquidness and musicality with more dimension to the soundstage.
Tone arm length
I assume this question is not brand specific.
However my question is specifically related to the Clearaudio Innovation Wood with the Universal tonearm, 9 or 12" options. The cost between the two is minimal, but I'd love to hear opinions on why one or the other is preferred.
Thank you.
