I liked them the short period of time I listened. Unfortunately I have a very short head (ears to top) and I couldn't adjust the headband small enough so that they would fit. My short period of listening time involved holding the LCS-2s (or maybe they were even LCD-1s, can't remember) in place with my hands. That's fine for a short time but rather awkward for real listening.
If Kevin will make me a free sample silver, balance cable for my HD800, I'll shill over there day and night.
Like Antonio, I haven't tried the HE60. For me, the HD800 gets out of the way of the music better than any headphone that I've listened to for more than 1 hour. I also like the fact that they are light and very comfortable. That's very important to me.
To me, the HD800 sound best being driven by a reasonably powered tube amp. This is despite what Kevin said about it. I really love the sound of them out of my KG-fixed SP Extreme and it's even better out of my Nugget Audio Menace TCLite. Maybe the tubes tame the highs a little for them or maybe it's just my expectation bias. Don't know but I like the HD800 well enough to sell a really nice HP2.
Again, the fit and comfort of the HD800 play a large part in me liking them.
