With the Dynavector cartridge, why not try the Dynavector P-75 MK-II phono pre-amp?
It's gotten great reviews and retails for roughly $800 US. I had one with my Dynavector DV-20X Low MC cartridge and the combo was very special especially when configured in Phono Enhance (PE) mode.
If not, you should also take a serious look at the Ray Samuels F-117 Nighthawk MC/MM phono pre-amp. It retails for $795 US and as most reviewers have suggested, this thing can beat phono pre-amps up to $4000. I've been using one for about 1 week now and it is truly an amazing phono pre-amp. Don't let the price fool you.....
