all i can say is I require about 6-7 clicks more volume of my Moon neo 430 on the LCD-4 than the HEK......the LCD-4 is a beast to drive but a great sounding can....I go back and forth between my HEK and LCD-4 and when I listen to one i say I like it best and then when I switch over to the other I say I like it best....
This is correct.I too have both the LCD-4 and the HE-1K and the LCD-4 requires more power to drive them than the HE-1K.
This happens to me too as I switch between headphone . The one I like best is always the one on my head.
Now I went and complicated matters more by adding the Sennheiser 800s to the mix. All 3 are great in their own way and on the same level IMO.
Thanks. Seems my LCD-4 is performing in line with everyone else's. Think I will check again with my dealer whether he loaned my a 100ohm or 200ohm model (he said it was 200ohm).
