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.

   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.

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
