A lot of mixes of contemporary pop and dance music has unnatural and ridiculous amount of low frequencies, it may not sound right or enjoyable to you when you hear an accurate presentation of it through reference speakers or the LCD-2. And just because you prefer the way SR009 or HD800's present it doesn't mean it's accurate or good. If you go to a live Classical or Jazz concert, the double bass doesn't get very loud because it is not a very loud instrument naturally, but in a CD mix, the double bass can sometimes be over emphasized. A lot of the punchiness of the bass drum is actually in the high mids, being able to hear the tightness doesn't mean it has a lot of sub bass contents, a lot of the time, sub bass is about actually feeling it physically. Like the HiFi system in my Lexus isn't particularly good, but one can physically feel the bass drum pounding when one listens to Maroon 5 with it, which no headphones in this world (at whatever price) can ever produce.
I've demoed the SR009/7, HE6 and I own a pair of HD800 myself, they may all be great headphones with super details, but I wouldn't call them accurate or neutral. Besides, being accurate isn't what audiophiles are looking for anyway, having an enjoyable listening experience is the main thing, isn't it? I would consider the LCD-2/3 as reference sounding personally, whether they are better or worse than SR009/7, HE6 or HD800 is all up to personal taste and preference.
