Thank you for the input guys. I konw next to nothing about EQing but I might as well try before replacing the HE400i as it will cost me nothing. I have a magni 2 right now but planning to get a Violectric V90 if I go LCD2 route.
@chry5alis
Can you elaborate a bit on why you prefer Teaks over LCD2?
First I must say, with the vegan pads and headband attachment the lcds are the comfiest headphone Ive ever worn, ideal for long listening sessions. But the sound was always a disappointment to me - very narrow soundstage for an open headphone. The bass was present but nothing special, imaging and delivery were good. I tried eq'ing but couldnt get the sound I was after and ended up spending more time on my fidelio x2.
The teaks are a lovely headphone, very sharp and fast, strong mids and good quality of bass. Soundstage is surprisingly good. I love that when I begin to tire of the sound I just swap the cups over to rosewood and start off again with a completely different sound sig. Its the rosewood cups that I have on just now.
Tl:dr
Lcd2 are an open can with a closed sound
Emu teaks are a closed can with an open sound
