Did anyone ask @drbond what the goal is with another arm? Improvement over the Reed (which looks very nice)? A second arm for mono or a cartridge that likes to see higher mass?
If you want an amusing read, go find j.g. holt's original review of the Transcriptor's arm- it is a hoot to read and the back and forth with the manufacturer in the follow up comments to the review are equally funny.
I have no overarching view on the merits of various tonearms- since I'm not looking at specs, and have to hear them in situ.
@mijostyn 's comment about the lack of bass from a conventional linear tracker is fair, but somehow, changing the cartridge-- Koetsu stone, adding subwoofers and readjusting the entire system to a new room gives me dimensional, very filled in bass that sounds natural on the lower registers with acoustic instruments- piano, double bass, etc. So, even that "truth" about the lack of bass in the conventional style linear tracker can be shaded by context and may be system-dependent in my experience.
