Need help finding a new phono stage.


I just purchased the Marantz tt-15s1.
It has a dynavector 10x5 installed on it.
I have a Cambridge audio cp1, and it sounds great. Which I'm not fully understanding because I thought that stage was for mm only? Can someone help explain this?
My amp is set 3/4 the way up for the volume level I like.. but even at full tilt it doesnt sound distorted or anything!
I guess my main question, and my next step is what is a good phono stage to upgrade to??
For now though I am happy. 
Thanks in advance.

I likely sold the cheapest ph10 few days ago and that was still above ops budget at $976 plus shipping.

Great phono though I have to agree but it was time for a change....
Really appreciate all the feedback. Thank you.
First real system and starting to truly shape up.
Every component has been purchased used but well taken care of and I've saved a ton from what I'm told.
Got the azure 740 a for $350
The cp1 for $100
The Tt-15s1 and dynavector 10x5 for $1400
Starter table was a new Rega Planar 1 with Nagaoka mp-110 I believe it's called.
All Canadian currency.
   three easy payments probably has the best advice. A high output MC and MM carts can be used with a phono stage with just a MM capable phono stage. If you want to go with a strictly standard (low output) MC cart be prepared to look at $$$ for one of those of quality.

   Turntable setups are one of the most challenging in the world of audio. Equipment and room have so much to do with sound quality that's it's impossible to follow suggestions from anyone. But, that's what these forums are for. To point out blaring "stay away froms" and intricate points based on personal opinions.

   If you have determined to use a particular cartridge, do some research on that. Don't rule out the used market either for a phono stage. I was able to obtain one. It is a Graham Slee at a reasonable price ($700). If you Google that you'll find gobs of info. Important about the Slee units is to use his dedicated power supply (PSUI).

   I'm sure others have suggestions based on there own experience. Good luck to you.
