I know this has been asked before but I'm wondering why sound is so different when listening from Kemper headphones output and from my Saffire pro headphones output. Kemper is connected to audio interface analogically. ( Main outs to Inputs 1 & 2). Sound is very rich and full when listening from Kemper headphone output but very flat and dull when listening from audio interface headphone output. (by using same hi-quality studio headphones) Settings should be OK. I also checked Saffires settings and they are ok.
Any ideas?
