Cambridge Audio Azur 640A V2 phono stage.

I have just got hold of a C.A Azur 640A V2, which has no phono stage, so I am currently using an old Pro-ject Phono-box MK1.

Has anybody compared the Pro-ject to the optional CA phono board, and is it worth getting one fitted, instead of the Pro-ject?

My other option is keep the Pro-ject, and save up for an improved external stage.

Thanks
