Cambridge Audio RIAA-Phono Stage "CP-2" (CP2, similar to AZUR 651P) vs. new Model DUO

A friend of me would like to buy one of the above mentioned models. According the images from inside the old model "CP2" is the better choice - so I think.

Who have heard both models ?

Thank you for comments.

Is the newer DUO discrete or IC in the input stage?

The older CP-2 model shows encapsulated "discrete low noise MC input stage" and same of the MM. Is the newer DUO discrete or IC in the input stages?
