Hello Gemini,
Re-visit your entire setup and verify that your VTA is set correctly - that the rear (bearing) end of the tonearm is not too low.
Your starting point should be a headshell mounting surface that is parallel to the record.
If you have any sort of tapered tonearm wand, place a small, parallel sided block on your platter to compare against the under side of your headshell. This will help you from getting confused by all of the funny angles.
If you own a Rega tonearm, you may be in for some grief, because they have limited VTA adjustment (depends on the thickness of the armboard). This, when coupled with the fact that Dynavectors are taller than most cartridges can mean you have your work cut out for you ... or not.
The vast majority of cartridges are within .1mm of 17mm in height - vertical distance from the top (under side of the headshell) to the record surface. Your 10x5 is specified at 18.8mm tall (the XV-1s is a "manly" 21mm tall, BTW).
You can check all of this on the Dynavector site
