DynaVector DV505 is it worth the hassle?

Dear Erik: As all those post I agree that the 505 is very simple to set-up even is more simple to setup in an arm board because you could need no drill holes to fix it ( of course if you want it you can fix through screws. ), you can do it using only a double sided tape ( like the one used to fix carpeting/rugs.
This is the way that I use it all the time in different TTs and works really fine and you can mount it evrywhere in any surface type.

Now, Albert point out some VTA/warps problems because the 505 design, well I have to say that I never had any single trouble or sound degradation due to what Albert post that certainly he had.

This is a " surprise " to me because a big part ( main ) of the 505/507 design is really that: the very high tracking " resolution " of the tonearm, here it is what we can read in the 505/507 Dynavector manual:

+++++ " Conversely, the
vertically movable sub-arm is made so light that it never lets the stylus jump the groove of even a disk
with warp(s) previously unnegotiable. " +++++

Lewm, both the 505 and 507 are dynamic balance design and as I already write here I never had/have a single trouble about and in all my audio years of experience this is the very first time that a Dyna tonearm owner has a complaint on the subject.

Dear Lewm: Take a look to the 505 manual here:
" 6. Arm resonance in low frequency range " , it is very objective to understand what you ask.

Now, the 505 has a low effective mass ( sub-arm ) against the main arm. It is light, you speak about the 15gr headshell weight but this is the weight not the effective mass that has a direct relationship from at what distance ( from the pivot ) is that weight ( 15grs. ) that in this case that distance is extremely short and this fact gives ( on the vertical way. ) a lower effective mass than the 15gr. weight.

Here it is what you can read on the 507-MK2:

" 2. What is the bi-Axis inertia controlled tonearm.
The tonearm is required to fulfill two functions so that the cartridge can reproduce the exact signal from the record groove. One of these is to hold the cartridge stationary at audible frequencies so that the stylus and cantilever motion is translated into a music system without losses.
The other is to allow the cartridge to track warped records.
These require totally contradictory properties from the tonearm and so all conventional tonearms are a compromise between the two.
However, a very reasonable solution exists in the bi-axis tonearm.
The bi-Axis inertia control tonearm is in effect two arms in one - the main arm beam has an effective-mass that is 3 or 4 times higher compared with conventional tonearm
but moves only horizontally. On the other hand, the sub-arm has a lower effective- mass than any conventional tonearm but moves only in the vertical direction.
This combination means that the high effective-mass in the horizontal direction holds the cartridge steady at audio frequencies, especially at low frequencies and high groove excursions, whilst the low vertical effective-mass allows unmatched warp riding performance. "

Lewm, you can always ask directly to Dynavector whom can/could give you a lot better explanation that I can.

I think that we can give you only what were/are our each one experiences with that tonearm design.
