Cartridge suggestions for Rega P9


I have a new Rega P9 with the RB1000 and I am using a Van den Hul MC10 Special cartridge. I have Naim equipment and was wondering if there are suggestions for a better match of cartridge? I sometimes feel that I am not getting enough out of the current one.

The Denon DL103 will work in the Rega arm and sounds superb. Only around $200. Sounds alot like a Koetsu black. I use one and really like it. Also recommend Shelter 501 or 901, superb carts. The 901 is a contender for one of the best, and costs about $1300.
The low output MM/iron Grado Reference line sound fantastic on the Rega tables. You'll need a spacer ring, but it is cheap and simple to install.
Thanks for the all the replies.
I agree that the Van den Hul MC10 is a very good cartridge and I will probably consider a pre-pre amp.
The P9 with RB1000 is a fantastic sounding TT. Much more detail and more full sound compared to the P3.
Has anyone tried either the Sumiko Blackbird or the Ortofon Supreme MC30 on the P9 + RB1000?
