I could be listening a bit louder than you, won't argue that. Would love to measure it, but have nothing to do it with. I usually just turn the volume up until the vocals get right sound. But with magni 3 there seemed to be some issues with power, they jsut somehow did not sound full. While my 600ohm reference version did. This is one of the reasons I say they are completely different headphones. Second set of these babies is a good idea nowadays, after all they are no longer being made(I would go as far as to say nothing like them is being made anymore). Perfect reason to get two. Though would suggest getting the gold if you get a chance for them, they are definitely worth the extra costs. Depending on where you live these can be easy to find. By the way which pads are you using? I ended up repairing the original ones, by cutting them open on the outside and replacing the foam with Brainwavz xl memory foam in them, seem perfect so far. Every other that I tried changed the tonality by some amount. Like the Brainwavz hybrids where the worst, treble sounded squishy with them and over bloated bass. Velours seemed the best ones so far, though stock ones still rule, with Brainwavz velours next t best option. Sennheiser's own pads are all to thing, the original ones where 2,5 -3cm thick. Wish someone made pads like the original ones, seen one guy selling his hd 540's with pads made from similar cloth but no idea where he got them from.
