I owned the LCD-2 for two weeks. Think I was in the second or third batch... I never did try them out of a system that was supposedly ideal for them. The bass wasn't the worst. It's definitely linear on paper. High notes are a completely different story. Wood winds and brass playing the very highest notes and their harmonics: had to pinch quite hard to hear anything... The HD800 did this much better (out of that one system) and I made a conclusion that they have much more potential than the LCD-2, in both bass and high note department. It was much more relaxing to listen to as well. In comparison, the LCD-2 tended to sound monotonic. For a musician, with whom I made these observations agreed that the HD800 were much more clear if he were to tab notes, for instance.
I have to add though, that for the two or three weeks when I had the LCD-2, I noticed that they were very picky with regards to the amplifier. Tried different tubes, solid states, visited different shops: ended up sounding the best out of an iPod. Out of a Naim headphone amp, the K701 even bested it. It brought absolutely nothing to the table, instead of some monotonic low-bass rumble, no other headphone which I've heard, can reproduce. But that might've been the setup as well... Don't get me wrong, I probably could have lived happily with them if not for direct comparisons. I thought I heard everything, but I didn't
On paper though, the LCD-2 seemed to show some very low frequency ringing, if I remember correctly. Even if it's inaudible, might it have some kind of an effect on the higher bass-frequencies? I understand most of the basic graphs, but am no expert. Sorry for derailing.
On topic though, I have not acquired an SRH940 yet. They are not my reference and I have not formed a real conclusion yet. I like how people say they
don't have any "visceral bass". One fine head-fi poster noted that headphones indeed are not able to reproduce natural reproduction anyway (at least when it comes to a physical feeling), so why not concentrate on what we're able hear from the music. "Bass-light" cans just tend to make every note audible to their pitch, much easier than a bass-monster, from my experience.
Correction! I reread my post and did not mean to say the LCD-2's have bloom exactly, it was just "monotonic" in comparison. Still better than many other headphones, especially Ultrasones.
