Yeah, I think that's it!
I don't think they need any mods right now with the 900X pads, I find them sonically very pleasant.
I will of course try the Hifiman velours and leathers but I wouldn't be disappointed if they don't work
It's strange with the off-balance thing because I didn't have this with other headphones but I don't think it really is a mismatch. When I run a driver matching 10 - 20.000hz frequency test that sweeps the whole frequency range, there seem to be bass only in the right channel only and then up from 100+ it goes back to center where it should be.
Then I swapped the sides and it's still on the right, What???
So... it's not really present in any songs as when the bass is center in it, it is center, when it is right/left is is too...
I dunno, must be THE MAGIC WOOD!!!
I still do regard them as a refined 900X though - Better highs extension [I was hoping for it], the bass is tighter but can punch too, it is more coherent and linear IMO, midrange is better balanced, soundstage more accurate. I didn't notice any minor differences in it's width or depth but it is expansive.
Oh, and it's so pretty and lightweight!
[The 1000X pads should be banned as a torture device, seriously?! both thinner AND smaller than the 900X pads?! How is that supposed to fit me!!!]
