On the subject of neutrality - I always thought that the HD650 was more neutral than the LCD2s. To expand further, in that more random tracks sound tonally correct on the HD650 than LCD2 to me. But I suspected in the past that its hard to gauge without a visual reference to know the physical distance and intention.
I was watching movies again late at night, which I don't normally do, or even use headphones for movies in general, but was able due to a recent back injury that has put me out of work temporarily. I came to the absolute conclusion that my R1 LCD2s are actually overall more neutral to me than all my other cans for watching movies. I love movies - good ones and hold the highest rentals by far in my DVD store.
I find the human dialogue with visual distance cues makes pointing flaws in tonal balance so much and easier than music without visual reference as I don't always know what the intended effect is. I explored this in a thread I started in my early days of headfi here, in which I criticised the K701 and eventually settled on the HD650 because it was much better to me.
So continuing from there I use the HD650, but quickly realise that the male voices were too chesty even when the characters were portrayed at distance - intimate when it shouldn't be, a bump at approx mid bass. It started to annoy me - and I thought I needed something between HD650 and K701, and the HD600 came to mind. So I will purchase a HD600 for movie watching.
Just for giggles I tried the LCD2s - because they are too heavy for movies for me. But WOW. I have the R1s and I don't think they are perfectly neutral, but they come closer than anything else I have ever tried. The HD650 midbass boost in male voice were corrected - still not perfect, but more able to sustain an illusion of making me feel like I am in the movie. If I had to EQ - something along the lines of Ham Sandwiches posts previous would suffice, just a touch more in the upper ranges, but it wasn't absolutely necessary.
The only problem is, I can't buy a HD600, even if they are more tonally perfect for movies, because if driver speed does such wonders for instrument definition, so that I can't really go back - the affect for movie audio is no less profound and at least equally as astonishing!
So many times when sub bass kicks in - I freak the hell out that a subwoofer has been left on - except I sold my subwoofer ages ago, and they were never that good! Yes trucks actually sound like trucks, industrial equipment sound exactly as such - like I have never heard them recreated so accurately. They never cease to amaze me these LCD2s, and I only have the R1, I need these R2s whenever my finances recoup.
