That's what I needed to hear. I've got a vali on the way to me from @Textfeud.
What dac are you using with the vali and the hd560?
The thing is. I bought these headphones used and when they arrived i washed the earpads and replaced the inner foam because i couldnt afford new earpads at the time. So basically it's the first time i hear these headphones the way they should be heard.
The definition declined a little bit but i guess i prefer it this way. With the old earpads i could hear every imperfection and feel almost every vibration from the drivers. That was really uncomfortable...
The bass tightened and is more pronounced now, the highs became more tamed (no more cringing), the sound now feels that comes from the air and not directly from the earcups. Even if i concentrate on the sound i can't distinguish exactly from which earcup is playing what. I feel that is closer to listening to music on loudspeakers, airy and open sound. I can almost distinguish the height of each instrument is being played. In terms of depth i don't think is that pronounced compared to the height. I guess that's what you guys call a big soundstage.
The violins for instance now became sweeter. I can hear the violins on this piece (http://www.chesky.com/vivaldi--the-four-seasons.html) and i can almost smell the wood that made that beautiful instrument. I know it sound crazy. I can't find better words to describe the feeling. =/
In terms on comfort its obvious that the new earpads make a huge difference and in lookd too. The headphones now look and smell like new xD
The 2 only downsides are: 1- the price. i paid more then 50€ (including shipping). 2 - when i hear musics which contain words with the letter "s" i feel that the s is very pronounced. It's weird.
Anyway, all of this to say that the earpads make a HUGE difference in sound. Conclusion that the folks in the HD540 thread have discovered long ago =P
Do your HD560IIs contain a foam disc in each earcup? I feel that both HD540II and HD560II benefit from a foam piece in each earcup as this helps to bring down any excess treble energy which would otherwise be interpreted as a hint of harshness/brightness. The driving configuration is also important. If the source has sibilance, these headphones will also have sibilance. Tight headband clamping force will also affect the sound and as you say, the earpad shape and materials are also very significant.
Hmm. This thread's getting kind of Freudian.
