First to disappoint you all. No, I did not create a markl type mod for the ath-m50, sorry for getting your hopes up. Now for the point of the thread.
The problems that the markl mod fixes in the Denon Dxk line seem to be the same problems that many people have with the Audio Technica ath-m50's: to much bass and recessed mids. So lately i have been thinking -- what if someone were to create a markl type mod for the M50's? Have any of you tried to create such a mod? Discuss!
