No, AKG400 was with stock pads, I have taken them to listen about year ago. Do AKG601 need some warming to show their potential? I was a little dissapointed - I waiting them for a long time, at least buy them and such sound... Can't say anything about high and mids - they are very clear and airy.
Hello. Such a big tread. :-) I also have a pair of AKG 601. But I think they have a weak bass. I know that they are open and dont wait a bass like a Denon AH-D2000 from them. But AKG 400, that I listened earlier have a more bass I think. Is this normal? Or I must warm them? They are not new, I bought them on Ebay. Thank you!
P.S. Dont punch me hard, ok?
