I have owned two C712s but never used their phono stages. However one of the guys I got one from did and he thought that for the money, it was quite good with strong bass, good coherence, and nice soundstaging - just like the line stage. Use it for a while and make your own decision.
Of course, if you spend more money on a separate one you can do better. But that is left up to you and your budget.
