IMO, the Spirit One doesn't sound like a $300 headphones.

Well it looks like you can get it new for about $200, and even less for open box models, had me thinking for maybe a little less than what I paid for the 591 I could get the spirit one, which you HiFi(I think it was you) said it was the better sounding cans.
Anyway to mod the 591 to sound a bit less dark?
In case any one is interested, it seems like ourfpshero is selling his for $150 (http://www.head-fi.org/t/637751/pioneer-se-mj591)
LOL!
Hahahaha! 
Sorry battle, not laughing at you. It's just that, well, almost everyone who has ever owned these cans can understand that sentiment exactly.
On some songs it's perfectly acceptable, while other tracks makes you wonder why did I get them. I guess now I know what you guys mean about these cans. This is the third pair of headphones I got this week, and so far this one has me the most confused on if I like the sound or not. If I return it, I think I may just save up for a P3 or something a bit less dark(that isn't overly bright).
TELL ME ABOUT IT! 
Actually, here's the thing. If you just listen exclusively to the MJ591, you'll be just fine. Seriously, no worries, and happy as a clam.
But the minute you put on another pair of headphones... any decent pair of course (i.e. not crap)... you're gonna have a WTF moment. Not saying it's good or bad, just very very different. The SE-MJ591 is truly in a class of its own (I can hear Beagle lolling from thousands of miles away).
Having said all that, Beagle did look under the hood and mess with it a bit. And he swears it sounds better (which I have no reason in the world to doubt) after he did what he did. Though I'm pretty sure it will void the warranty.
Also, I believe that both HiFiGuy and I have moved on from these being our mainstay portables. Not sure what HiFiGuy is listening to these days (one of the new UEs I think?). I'm on a pair of lovely IEMs at the moment (RHA MA450i), and I'll be transitioning to a pair of V-Moda M-80 soon.
Also, haven't heard the P3 so I can't comment on those.
Well my main portables are the Klipsch X5, which are really something when it comes to IEM. I was just looking to use at work, and home when I want to get lost in the music(where the X5 is for everything else), and my other set of cans are the old Sennheiser HD495, but those are open.I must have skipped it, but what did Beagle do to adjust these?
I wish the Magnolia at the BB near had those AKG 451 on the floor to try. Was about to get those when they told me if I get the AKG now, I can't get the 591 at the price I got it, because the pricing error would be corrected after I leave. :-\
How do the similarly priced HD25 II(with the faux leather and w/velour pads) compare to these?
You there, sir! I hereby award you the "I-accidentally-mentioned-the-one-pair-of-cans-that-are-more-or-less-the-exact-opposite-of-the-MJ591" award!!! Congratulations! 
He is 100% correct.
So disconnect from Head-Fi immediately, enjoy your music with your MJ591 and live happily ever after!
Is there a Nicorette sort of thing for Head-Fi? 
Hum, perhaps new sub-$150 FOTM headphones...? 
Can you elaborate a bit? Like give a quick comparison of their sound difference?
I would be perfectly fine listening for the most part exclusively to the 591, but I own some Klipsch X5, that I also use regularly. They sound is almost totally different, but yet there is something about the X5(or something lacking in the 591) that stops me from fully liking the 591. I think I am going to give it a few more days of full listening before making a full judgement. But, so far it's better than the other two I tried last week.
Yeah so my Sennheiser HD495 were sitting next to my computer and I had to put them on just for a fair comparison. The 591 has much better SQ and the pads are very soft comfortable, but total comfort the HD495 has it, which can really matter after long periods of listening to music. So, I guess I am going to have to return the 591 as they were tight, but didn't realize how tight they were until I tried another pair of can. :-\
Thank you though.
Let's not tempt fate. 
Well, the HD 25-1-II (I'm assuming that's the one you're referring to) has a prominent and punchy bass response, with reasonably good extension so as to be pleasing for genres like EDM. The mids are - as you would expect - a bit veiled if not recessed. The highs are ever so slightly thin, but otherwise have a good snap to them.
OTOH, the MJ591 has a smooth bass response that (for me) rolls off a bit prematurely. The mids are RIGHT UP IN YOUR FACE ALL THE TIME. And the highs are blanketed.
So depending on what genres you favor, you're most likely going to like one of them very much... and the other one decidedly less so.
Just out of curiosity, what were the other two?
Hmm, I had forgotten all about that. I tended to not mind the tightness at the time because I used them as a portable. So their ability to stay on my head during the hustle and bustle of city life was very much appreciated.
