Setup Dynavector XV-1s on SME V help


I am having all sorts of issues getting it tuned in. I do have it sounding very good but my settings leave me confused. My tracking force is 2.4 in a dynamic balance. My antiskating is set at 2.5 or abouts & the damping dip stick is all the way down. When I cue in the tonearm it always jumps right into the 1st track, never setting smooth. ON the Hi-Fi News test disk it flys across the blank space & then jumps over the next track almost to the end of the track. Kind of crazy. My VTA is level. I am loading it at 1000 ohms to great effect now & I can track the 4th track of the HiFI News & Record Review bias test track but with a lot of buzzing. I have almost no buzzing on the 3rd track. The arm resonance is about 9 hz or so in horizontal but harder to detect in vertical, but seems about the same.

Now w. my VdH Condor I had no tracking issues & itbehaved perfectly in the SME V. The Dynavector on the Ikeda never had any problems on the lead in groove (no jumping our bouncing) but it just didn't sound good (might have been the break in or the Ebony headshell I was using. I am waiting for a Dynavector headshell to use as the stock Ikeda headshell won't accomodate the Dynavector.

Anyone with any experience please chime in as I am totally lost.

Nsgarch,

Blue Tack was removed w. the Condor. I use an outer ring. The distance between the tonearm rest & outering is 1/8 an inch or so. Exactly between the 2 lines. Maybe it is out of adjustment. This would work very well, as I can pull the rest further out from the turntable and run w. no antiskate. The position of the arm rest would give me antiskate anyhow (I am not sure on this, but I think from the design principle, this would be correct, but it might be opposite as well.) You can test for this by placing the tonearm in neutral balance & seeing which way it will move once you lower the arm. The antiskate will pull the arm outwards from the spindle. It makes sense that you will need more antiskate the further in towards the center your stylus moves. The diameter of the circumfrence of play is getting smaller, changing the ange and creating a greater inward force on the tonearm/ cartridge. I wonder if the antiskake can be progressive as the tonearms moves throughout the record. Is it possible the tonearm has 2 different directional changes of antiskate as you play through the record due to the angle of the tonearm?? In a linear tracking this must be a continous change.
Dgad, Linear trackers don't require anti-skate because there is no torque created around a pivot point as in a conventional arm.

It sounds like your arm is set up OK, and I think the Dynavector must just need some more run in (especially since if I understand you correctly, the Condor is doing just fine with the same setup.)

If you want to check the anti-skate setting visually (which shouldn't be too hard to do looking at the front of the XV-1s) just shine a strong light at the front of the cartridge and as you lower the stylus into a groove in the middle of the first band of a record, try and see (it takes a little practice) whether the cantilever appears to deflect left or right just as the stylus hits the groove. If left, reduce the anti skate, if right increase it. Because the XV-S1 has a rather low compliance, it isn't going to deflect that much in any case, so you'll have to watch carefully, but you can certainly tell if it's way off either way, so start by turning the AS off, and then all the way up just until you get a feel for what your looking at.
Darren. Harry from VPI has always stated he believes antiskating is a crap shoot as it changes at every position as you play the record.

XV-1s takes about 300 hours to settle down. Must admit I never noticed any stifness in the cantilever, but then again I change VTA on most records. Is it sounding better?

cheers Shane
Shane,

It is finally getting there. In fact it is finally not jumping on the lead in groove. Things are fuller & much more life like. The Condor reignes supremem in the bass & detail camp so far. Not necessarily a good thing. I will listening to Bob's Kaya last night & while on the Condor I could here tons of pops on the record w. the XV-1s it was much more listenable & enjoyable.

Nsgarch. I am going to try the lead in groove test. I did try it & it is so difficult to tell because if you are not positioned centered over the groove you are going to deflect to drag the cartridge in one direction or another. Correct me if I am wrong. It is very tough. I did try using your system but found it very tough. Thanks though.
Dgad, You do this test lowering the stylus into a grove somewhere in the middle of the first recorded band, not into the lead in groove.

Yes I imagine it's a bit tough to read the movement of the cantilever with as low a compliance cartridge as the Dyna.
