I've owned the LCD-3 and heard the SR-009 only at audio shows so far, so take my opinion with a grain of salt.
I wouldn't call the LCD-3 a poor man's SR-009. I might call the LCD-2 r2 a poor drunk man's SR-007 though (which is being generous), and I'd definitely call the SR-007 a poor man's SR-009. While that might logically imply the LCD-2 r2 is like the SR-009 though, I wouldn't stretch it that far - IMO, there's a huge gap between the LCD-2 r2 and SR-009. There's already a big gap between the LCD-2 or LCD-3 and SR-007, IMO, and replacing the SR-007 with the SR-009 just widens the gap.
The closest dynamic headphone equivalent I've heard to the SR-009 is the discontinued (and increasingly expensive to acquire) Sony Qualia 010.
I'd like to know which posts you're reading, as I haven't recently seen anyone write that the LCD-3 and SR-009 are somehow comparable.
I'd describe the LCD-3 as a physical- and tactile-sounding sounding headphone with a highly pressurized (and satisfactory) bass - actually the most physical-, tactile-, and bassy headphone I've heard (eclipsed by only the AKG K340 in the bass aspect, though the Audio-Technica L3K and Grado PS-1 might come close) with a somewhat aggressive sound and a compacted soundstage. Actually now that I'm writing this and thinking about it, I can't help but wonder if the LCD-3 and AT L3K might be sonically close. That'd be a comparison I wouldn't mind doing if I had the chance.
The Stax I've heard aren't remotely aggressive-sounding and are very neutral. I know "neutral" is a word that's thrown around on Head-Fi a lot by a lot of people, but I personally don't just casually toss that word around for just any headphone, and "neutral" for me is pretty much only the SR-007 along with a select few dynamic headphones like the Grado HP1000 and Senn HD600, and the JH Audio JH13 IEMs. I wouldn't call any other headphones as being neutral-sounding, and I've heard most of the current flagships. By that frame of reference, I'd call the SR-009 relatively neutral too. I can put it this way too: I consider the LCD-2 assertive-sounding and the LCD-3 aggressive & forward. Compared to the LCD-3, I view the SR-009 as downright passive & laid-back.
And for anyone looking for bass in headphones, that just makes me want to ask what kind of music you listen to, because if it's pop, rock, metal, industrial, or electronic, which are all bassy forms of music, then I'd probably advise against stat headphones in general. None of the stat headphones I've heard are exactly bass monsters. If you want bass, I recommend Audeze, AKG (the K340), Beyerdynamic (DT770). I'd recommend the SR-009 for more refined types of music - classical, jazz, non-bass-driven electronica (i.e., ambient), bluegrass/folk, etc.
I just recently posted impressions from an audio show where I heard the LCD-3 and SR-009 btw: http://www.head-fi.org/t/612958/t-h-e-show-2012-newport-beach-ca#post_8454665
I've also written reviews of the LCD-2 and LCD-3 that can be found here, along with other threads covering some electrostatic gear like the SR-007 and BHSE: http://www.head-fi.org/a/asr-head-fi-threads-compendium
(I compared the LCD-3 to the LCD-2 in my LCD-3 review btw.)
I'll add this too: anyone who can't afford an SR-009/BHSE combo can get some of that awesomeness on an SR-007/KGSS. Anyone who can't afford the SR-007/KGSS can get a murky idea of it (and by "it" I'm referring to the SR-007/KGSS, NOT the SR-009!) on either an LCD-2 r2 + B22, or the JH13 IEMs. Anyone who can't afford the JH13 or LCD-2 r2 + B22 needs to either pony up their wallet or just go home.
