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.

Try the Mobile Fidelity . I have one on loan at home waiting my costly pre to be fixed. Very very good. Timbrally well textured, balanced and dynamic. Music flows easily. It’s very surprising.
The HI-VI analog guy on YouTube (Ian) likes the Schiit better than the Mo-Fi. I believe he has a video where he compares them head on. Good stuff
I feel your content with your set up, and the costs attached with achieving the level of performance your receiving.
If you do get the itch to change Phonostage, have a look at the Mr Nixie DIGNA.
I am a owner, and this is one that thoroughly satisfies my requirement.
It has multiple user settings as well,  the options to make changes, when using a MC have a great effect on how a cartridge interfaces with a system and the SQ.
