Couple of questions for the owners here, firstly I have a friend that has an E12 but only get to chat via phone with him due to distance so do not get to hook up to often thus have not heard the E12 yet for myself. His E12 (which he likes the SQ of a lot) is having a buzzing sound occur in the left channel only and is not to do with the bass boost feature and happens whether anything is connected to amp or not and this is just on battery power.
The buzzing has gradually got slightly worse in sound elevation meaning it is obvious to hear when listening to music. Has anyone else had this happen with their E12 or know what could be causing it at all?
Secondly is anyone using these with 400 or 600 ohm can's at all and if it drives them with good authority?
Oh, lastly is there anyone who can compare how this sounds to a TTVJ Slim if they have one.
Thanks in advance.....
