Well stunning job, I want this in mine, even when i love mine the way they are, just let us know if you are planning to made this for sell, you could begin to get some serious income out of this mod.....
Now, for the cable tweaker, please I would like to know which cable are you using for the replacement, I was thinking in the Canare Star quad, but it is a little heavy, though very flexable...and I have never seen the mini version...any suggestion here, now i have two pairs of CD3000, so modding one should be nice to compare both after......
BTW and FYI the original cups are not cheap plastic as many had stated, they are indeed made of an expensive "organic composite" according to Sony...LOL... sound quality apart of course.....
BTW, the new ones I got were a brand new batch, just imported, fresh made and targeted for the American market, with all the manuals and warranty card, in English, so the rumor of that they will be discontinued is everyday more and more in the dark......
