I've been listening to a Dynavector 20XH on my Rega P5 for around a year. Although I feel it's a pretty good cartridge I don't wake up to find album covers strewn about my listening room.
Today I ordered a Soundsmith Boheme cartridge. It's priced about the same as the 20XH. Apart from the sound, one advantage I see is that Soundsmith services and rebuilds their cartridges at very reasonable prices.
If you're considering the Dynavector you may also want to consider one of the Soundsmith offerings. I've been hearing and reading good things about them. I talked with the owner today and made my decision to try the Boheme.
