Question about Creative X7!

I have an X7 and I want to know if the RCA in’s analog signal goes to the ADC or the headphone out ?

Is it like (A) or (B):?

(A) RCA_IN > ADC > DAC > headphone out
(B) RCA_IN > headphone out

I have contacted two major reviewers and I get a conflicting answer, some of them say its (A) and some say its (B) …

I have also contacted Creative but I didn’t get a proper answer.

Is there a way to check ?
