Sad to hear that. I, however stick to everything I wrote, I even bought LCD-X and I love it
LCD 2 has problems with the dynamics, sector in which both x and 3 are quite better.
You may not like neutral sound. Maybe you prefer the more colored sound of LCD2, that is ok
.
However, I found LCD-X to be quite in another league than LCD2.
When i got HD800 at first I still liked LCD-2 better. In a few weeks or so, my LCD-2 gathered dust as I was listening more and more with HD800 and started to see the technical limitations of lcd2. This doesn't happen with X and HD800, or with LCD-3 and HD800.
I see you don't like HD800 either as you returned it. It may be that you don't like this type of sound and X comes closer to HD800 in some regards.
I also say that you think HD800 is lifeless. I didn't find them lifeless at all. Actually the dynamics on HD800 are wonderful. However you must be aware of the fact that if you put them just after the audezes, they will sound thin and maybe lifeless at first. You have to let your ears to adjust to them a little.
At first while having lcd-2 and hd800 the first day I ended up not liking either of them. After HD800, LCD-2 sounded muddy and damped and after LCD-2, hd800 sounded thin and lifeless.
Also, at first when I listened to LCD-3 vs LCD-2 I didn;'t realise how big of a difference there is between them and I thought that it doesn't deserve the money. After getting HD800 and got accustomed to them, I realised what good dynamics, micro-details and details are, what fast transients sound like, etc. This made me appreciate LCD-3 a whole lot more. So actually HD800 made me sell my lcd2 and buy lcd3.
You can see my evolution in my blog:
First encounter with LCD-3:

Then I started to realize the power of HD800

and started to appreciate LCD-3

So, I learned not to rush into the opinions from then. However, it is interesting to see the journey as it was.
