Really? I found them to be a night and day difference, literally (dark and bright).
The LCD-2's sound is much darker than that of the SRH940 and the soundstage is very narrow in comparison to the SRH940 as well. Treble presence and sparkle of the SRH940 are in a completely different league than the LCD-2 from my experience (like LCD-2 vs HD800 or HE-500).
I agree with the bass though. Although the SRH940 is lean on the bass compared to the LCD-2, the LCD-2's bass seemed a bit bloated to my ears, making the mids seem very thick and warm.
Yeah, highs in terms of performance were completely different, but soundstage differences don't register well with me when it comes to open vs. closed. Just a personal nitpick I suppose. I still love how the 940's work for every genre. IF EQ'D RIGHT
