I've had some more time to take in these cans with fazor, rear grill, and pad mod.
It's amazing.
I did not try the mods individually, so I'm not sure which one did the most for the sound.
When I wrote about my first impressions I was being conservative. I didn't want to be too influenced by the placebo effect.
The more I wear them, the more I'm starting to hear details I haven't heard in the prior ~20-30 hours, and actually haven't heard in any of my prior cans (Shure SE215, Beyer DT770, Senn HD598). I'm finally hearing the "expansive reverb" I liked in the SE215 and HD598. I'm hearing a lot more space between the details that was flat before. I'm hearing more clear sparkle where there was harshness before.
There is one downside, I have found a handful of recordings so far that sound a little too warm, for example Daft Punk - Random Access Memories. Although certain details don't have that excessive warmth, so I suspect maybe I'm hearing the warmth they intended all along...?
Prior to doing the mods, I eq'd the bass to be louder up to 77hz because I thought, "even if I don't like these cans for everything, at least they have good bass". Since doing the mods I mostly listen to them without eq, except for certain genres. Even when flattening the eq, Daft Punk - RAM seems too warm, but maybe I just need to get used to it.
For custom designed pads visit our site (google my nickname). We had many orders for m1060 pads last months. Hope there were headfiers among customers and someone will share impressions here.
I might be interested in trying out some nicer ear pads in a couple months. I don't love the Velpad I'm using now.
There is a typo on your site:
