I was wondering if you felt the kobiconn setup needed a ground on portable battery powered devices such as the clas db when connected through a balanced cable to a portable battery powered amp?
I recently received the headphone lounge spc kobiconn cable that I ordered. I must say I am completely blown away by the balanced sound of the 650 paired with the duet and db. So much so that I haven't used my jh13pro fp's. Complete sonic bliss.
