DynaVector DV505 is it worth the hassle?

I get it. The vertically pivoting portion of the tonearm can develop a relatively high effective mass AND be "light" in weight at the same time, due to its short length. I am especially intrigued by Raul's mention that it can be used with no drilling, by fastening it to the mounting board with double-sided tape.

Lewm, ONLY the 505 can be fastened to the amrboard without drilling. The 507 is another story. You need to drill to install the 507.

Hope this helps clear things out.

I am also considering a Dynavector for my new Raven. In my research I came across another curiosity. Dynavector uses Stevenson's alignment rather then the more common Lofgren or Baerwald. Is this something to consider when choosing an arm or are the differences really just academic?

Motnic,

The mounting template that the 507 MK II comes with has a pivot to spindle distance of 226mm and an overhang of 15mm for an effective length of 241mm. Null points are at 60.1mm and 116.5mm. I don't know what alignment method this is, but I've tried Loefgren and Baerwald and both worked fine for me. I currently have it set up based on the template and the cartridge mounting gauge provided. I use what was provided with the arm because I find the cartridge mounting gauge very convenient and it allows you to set up the null points as well.

If the tonearm is mounted based on the template provided and then one decides to use Lofgren to set the overhang, the Dynavector headshell barely has enough room for the cartridge to slide to where it should go. I experimented with a Sumiko headshell and had no problem setting it up since this headshell has long mounting slots for the screws.

In my experience, either using Loefgren or the template provided with the arm, I always got clean and undistorted sound from the arm.

Best Regards,
