Hi
Helene is far from bright by any means.
You mentioned that you used xlr output with pseudobalanced input of Genus.Helene xlr being floating output is incompatible with pseudobalanced(Genus xlr input is pseudobalanced) as this creates high pass filter which you will get tilting freq responce which is audible from first seconds.Strange that you were hearing with this connection for days(floating xlr into pseudobalanced ....
Rca connection only when no true xlr input is present.This is what i adviced,not that Helene is bright
Mind if I ask for some clarification on what a pasudo balanced input and floating balanced output are? Are tjose just SE signals over a balanced connector? Or something more complicated?
