Hi Brooko, I trust your measurement and is firmly in the camp of if measurement shows no difference there should not be difference. However, I've tried using a Mee Audio P1 cable on my Orion and it changed the sound DRASTICALLY, thou in a bad way. I believe that would actually shows up in measurement although I've no way of measuring it here in SG. I'd love to do it if I could. I'm not sure how big is the difference in the impedance is between the Mee Audio cable and stock Orion cable. But I really was caught by surprise how big of a change there was because I *did not* believe in cable at all prior to that, so there was no perception bias too in my case. Off-topic: is a FR measurement equipment expensive?
