100+ Head-Fier
Well that'd be annoying if that's the case! As I say, on some recordings I do notice it slightly with other pairs, its just that the 540II makes it unbearable, so I'm working on the assumption that its something in the system first. last night I was hoping to rule out my soundcard as being the problem, so was going to try hooking up a spare dvd player to my headphone amp and play a cd, but apparantly the thing has died since I last used it, and my bluray player doesn't have a line out. I did try reseating the op amps, as I know that has caused problems before, but no joy there. I'll have to see if I can pick up a cheap cd player from somewhere. Only other thing that I could try is that I do have another soundcard that I could try swapping out for, which uses a different dac chip, which could have a less bright signature (though not as detailed) but oviously that wont be removed from any pc-related power noise if that is the issue.Have a bad feeling that in your case the hd 540 has a damaged driver.
So far have owned 4pairs of 540rg 600ohm, 1 pair of hd540 rg 300ohm version. 3 hd 540II, 1 hd 250, 1 hd 560 Ovation, 1 hd 560 ovationII, 2 hd 480s and a hd 480classic. All of them where in ideal condition except for hd480 classic. All of them also had the impedance pretty much as advertised, except for the hd480 classic which reports 20ohm less than what it's supposed to be. The sound it produces at lower levels is ok with a bit pronounced s sounds, but once you get to normal listening level it's painful and unbearable. Both drivers are broken, have no idea of exactly how, but suspect voice coil may have developed shorts or something. No modding or dampening can fix this, only a new headphones.
Best bet is if you know anyone with a pair aswell go to them and compare to yours, these headphones should not have any issues like that.
Another way to see if it's dampening/pads at fault is to remove the pads and all foam and have a listen holding them closer to your ears, if they sound good it's the materials of foam that are at fault, if not the drivers are faulty.
