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.

As long as it is driving the speakers to your satisfaction, there is no issue with turning it up so high. Remember, in most cases, a volume control reduces the volume by offering progressive resistance to the signal such that full volume is the actual gain of the amplification stage. So the less resistance used by the volume potentiometer, the better the sound.
You might be able to find a used Nova Phonomena within your budget. Excellent phono stage. If you prefer new, check out the Parks Puffin.
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.
