DDJ RZ phono pre amp - playing vinyl

I have read a few posts regarding the phono pre amp circuitry in some of the lower end controllers being poor and only suitable for DVS use.

Can anyone shed some light on wether the phono pre amp circuit in the DDJ-RZ would be of the same standard to these? 

or if not, what is the equivalent in the DJM mixer series?

I am looking to buy turntable, and need to know if i am not likely to get an acceptable sound from routing them through the DDJ-RZ internal mixer.

I don't mind if it's not audiophile quality, but don't want to spend out on a turntable if the quality is going to be poor.

Any advice on this would be greatly appreciated :)
