Hello Daryan I also have gefells and I have schoeps.
I like to run the gefells XY and I never run the schoeps that way. You will find many gefell owners run xy.
I am aware they are one of Mr Oade favorite mic for rock music. This is one of his posts regarding gefell configuration.
Hello !
Yes, they have an amazing amount of depth and spatial detail, the
best of any solid state mic I have heard. Cards will always record
more of the room and have a "softer" sound than hypers ( your
friends "louder"), which have a more forward or aggressive sound (
true of most all brands). I run the hypers in most indoor venues due
to poor acoustics, but will use cards or omnis outdoors. I feel the
MG mics sound best run X-Y, I have tried most configurations with
them and come back to X-Y for all of their directional mics. They
also have a very present sound, noticeably lacking any film, again,
tube like in this regard, I love em !

I am not saying this is the only way to go but I am aware he has much experience with these mics.
Peace out,
Wiggler
