If it does maybe I can try it myself and help modify the mods so it gets similar improvement with less work where even non-DIYer can do it, then you don't have to go through the trouble of becoming MOT.
My modded pair just arrived on today's mail. Everything OK, just played a tune to see they work well.
Interesting, very first impression is of a very balanced sound, kind of "bold" tonally and quite open and airy spacially.
Since I don't think they have more than a couple of hours of burn-in, I'll be playing them for the next days before making any judgement.
Mark did a great job preserving the lettering on the cups. No one would say those cans have undergone some surgery. Just for the pads being thicker and a bit harder on touching the skull than what I recall from the stock ones, but still very comfortable.
I've tried another mod, in addition to the ear pad mod. I put a some foam near the back part of the pad, but so it touches the ear. It angles the drivers further in front of my ears and pushes the drivers away from them as well- resulting in a huge increase in soundstage, does not compromise bass either.
I am still debating if I like it or not. It works well for some music like jazz and classical. But vocals seem to be too far away for rock oriented music. I need to find a way to make it easy to attach and to remove, so I can tweak it for different music.
Hey, markl. I'm getting ready to dive back in and update the mod (if you don't remember, I'm one of the first to do the original). One question on the foam that you added on top of the Dynamat... are you using anything to make it stay in place? The picture makes it look like it's sticking to something but I can't find anything in the directions that verifies this.
