I have a dilemma. I bought a vintage pair of K240 DFs some months back. Basically, I love the mid range and treble on these things, they are so flat, neutral and clear (despite missing the very top end, it sounds), but I cannot abide their lack of bottom end any more! I bought a tube amp (Bravo Audio Ocean) in the hope of driving them better and warming them up, which worked to a certain degree, but I realise that they are never going to satisfy me with their lack of bass response. My question is whether I would be able to retain that open and neutral mid and top end plus get the extra low end response I want by upgrading to one of the K702/Q701/65th Anniversary editions? I do hear that those cans also lack low end punch? I'm not a basshead by any means and that is reflected in my enjoyment of my HD598s, but I wouldn't want to invest in these next level AKGs and be disappointed again.
Can anyone with relevant knowledge chime in?
Thanks in advance!
