I am not sure if I mentioned this a while a go. Did anyone try to remove the outside grills? I tried this with my lcd-x a while ago. The results were very nice. The soundstage decompressed quite nicely. It was so decompressed that it gave HD800 a very good run in size, but also being more natural. Besides this, the bass good deeper and more detailed and the instruments were better extended.
The treble was more present and sparkly without the grills.
Curious if anybody else tried this.
My relationship to the LCD-X is quite ambivalent. Important to know, I bought a very early one from the very first batch. Long before you could actually buy it here in a shop. I bought it directly from Audeze, despite warnings, that Audeze previously had some issues with early serial production. Me idiot just couldn't wait.
So what happened? Via my LCD-X the upper bass was (with a lot of my music) bleeding into the lower midtange and making the whole ptesentation sound matt, muffled, intransparent. With some cinema-style loudness and whatever else effects treated music it created great results. But with "just" realistic, rather untreated music the result remained unsatisfying, however long I burned it in. Whatever cable or amp I used (some tube amps with suitable music were even on killer-level, but again, only with the "right", enhanced music as for example Yello and alike)....
I was considering to take the grills off, but thought that alone impossibly could make that difference. Well after reading your comment, I thought I just give it a try. I took off the grilles, removed all the syntethic felt behind the grill and put the grill back.... and what shall I say, I do not recognize this headphone anymore... it is a completely different league. The mid- and highrange came forward just enough to make it now a balanced sounding headphone, open, transparent, clear and with serious punch... all there.
Shame on me that I didn't try that earlier, especially since I am quite a DIY guy.... well, better now than never.
I saw other comments here saying they didn't like it without grills. I can imagine, if you have an LCD-X that already sounds "correct" with grill and syntethic felt, it certainly will be too bright / harsh without it. So what I write here might only be valid for my specific LCD-X.
...so @dan.gheorghe, kudos to you...
Thanks and cheers!
