Rega P5 W/RB700 Cartridge Match / Mate ?

OK, I love analog but I am a plug and play individual. 2 questions
Have a Rega P5 with the RB 700 and for now I have the Dynavector 20XH which is 2.8mv. I use MM on my Phono Pre.
I do have the outboard power supply for the Rega.

Question: 1 The internal wiring is Klotz what ever that is. I read about the Incognito Wiring and wonder?

Question: 2 I will keep the 20XH in place for now as I am getting a new Phono Pre next week and really want to hear it the way it is. I like change, or at least to try other cartridges. What cartridge is a good mate for this arm?

I read all these specs and after done reading I still don't know any more. I think it's a audio brain lock when it comes to analog.
I don't want to take out a loan on this cartridge so lets keep it 1000.00 or under. ( give or take ) a little.

I do like the Dynavector sound but I am not married to it.

Suggestions would be appreciated, "Incognito - Cartridge"
