I've had these for about 24 hrs now and my initial impressions remain.
Some more thoughts.
Comfort: For some strange reason these are more comfortable even though they're heavier than the LCD3s. The microsuede is softer than the leather on my 3s so much so that sometimes, the tips of my ears touch the drivers inside. There's a nice snugness to these and I could easily wear them for 5 hours continuously.
Fit & Finish: Absolutely gorgeous looking. I've owned the L3000s and if those were the Rolls Royce, these are certainly nothing less than the Bentleys. The microsuede smells like the interior of a spanking brand new car. Yes, it actually does!
OK. Now that we've got the extraneous out of the way lets get down to how they sound.
The highs: Sweet. That's one word which keeps coming to mind. Sweet. Quite a bit more extended than the 3s. There is absolutely no shrillness or even a hint of harshness. This was one area where I thought the LCD-XCs easily beat the LCD3s
The mids: Very clean and neutral. No sibilance with female vocalists, which for me is very important. Brightness I can endure, sibilance, absolutely not. Male vocals sound real and natural.
Here the 3s take the cake, although the XCs aren't far behind. Just that the softness, the delicacy, which I get from the 3s, is missing.
The bass: Theres a heft to it which is missing in the 3s. Better slam and a nice punchy feeling to it. Only the texture is still better on the 3s.
Maybe it's because the XCs are faster.
The LCD3s are a great pair of headphones, my personal favorite and the fact that these come very close and infact are better in certain aspects, speaks volumes about the LCD-XCs.
I think we've got a winner here.
Thats it for now, more later with photos...
