EDIT: The guy got back to me and confirmed the Y cable approach to be doable.
I just got my second Golden Age Preamp and have one Golden Age EQ., which gets linked with the preamp via a balanced jack.
A guy from Thomann told me I will need a second EQ in order to be able to use the new preamp. But I’m still wondering whether a Y cable (below) would do the trick
Thoughts?
