Dynavector DV 507 MKII

Dear iSanchez: Do you already try it in static way?, no?: why don't you try it and share with us your findings?. Thank you in advance.

Regards and enjoy the music.

In my experience the dynamic gauce is presice with some combinations of headshell/cartridge and not so with others. More important: Going back and forth and the dial will show the same value.

I just tested setting the VTF static yesterday and in my opinion the arm sounds more open and faster in the midrange this way. Kind of similar to less damping fluid in other designs if you understand.

In my system (Acutus/DV507MKII/XV-1s) I must say I prefer this over the pure dynamic force.

It is just as easy to adjust VTF this way as you could arrange the weight to your minimum value and apply additional dynamic weight.

Or, combine the two to find the optimum amount of "damping".

Thanks Raul.

Do you fasten the different screws hard, loose or something in the middle?

I'd like an explanation as to how you think this is possible.

I've used 9 cartridges with 3 different headshells and couldn't disagree with you more.

The only possibility IMO is you do not have the arm leveled in exactly the same position at "0" VTF.

Thanks in advance.

Hello Raul,

I ran a quick test this morning and my first impression is that the sound is more articulate and it has more dynamic contrast with the dial set to zero and using the sub weight to set the appropriate VTF. I also perceived a bit less bass weight, but I cannot be completely sure about it. It might be simply the effect of tighter bass.

From a more technical perspective, with the dial set to zero the sub weight needs to be closer to the pivot in order to achieve the desired VTF. This creates less moment (m=d*f) as the sub weight mass vertical movement is shorter, hence creating the opposite of a craw bar effect.

The less moment generated with the sub weight closer should produce even a faster vertical recovery when the short arm maneuvers a bump or a warp, which is one of the unique design features of this tonearm.

Thanks a lot for the tip. I never thought about it, but it makes sense now that I think about it. I discussed my notes with a engineer friend of mine and he says it makes sense as well.

Best,

iSanchez

all you guys that have experience with the DV 507. How good is it? Any down side? (except the price)?
