BTW, T50RP now about $76 with the 17% off:   http://www.amazon.com/Fostex-Semi-Open-Headphones-Commercial-Applications/dp/B0002MT6RY/ref=sr_1_1?ie=UTF8&qid=1417846197&sr=8-1&keywords=t50rp

nm...

Got both ESW9A and A900X, will see which one I like

Hmm, listing ended. Hopefully seller honors these few purchases.

Yea, whatever, it's 4 bucks, got 3...hopefully they are legit.

Yea, still not decided on which one though. Want to hear them first hopefully.

Yea, I've read that too. Maybe I will look at the K545 instead of K550 if I do AKG.

Guess I'm going to have to flip a 4-sided coins...840/k550 or k545/HP100/ZMF

O geez, that is a lotta information . I will start sifting through...   Hmm, I see. That ZMF thread sells it pretty well. Damn, now I have several headphones for consideration from all the reading and this thread, but I have no means of auditioning any of them :(

Hmm, maybe I will give modding T50RP a shot. Is this the thread for ZMF you are talking about (http://www.head-fi.org/t/667870/review-zmf-modified-fostex-t50rp-superb)?   I'm looking for closed cans for portable use, that's why I'm looking at the A900X.

Thank you that was quite informative! Do you know anything about a few of the others ones I listed (A900X, HP100)? Also what do you think of the Mad Dog as a portable (assuming you drive it with something like the X3)? Or the T50RP even?

bump

Yep, already done.

I see. Though the A900X are a bit more affordable. Would the A900X benefit more from a meatier DAP than the momentums? Need to try more. More suggestions are welcome!

Interesting. I never really thought of it that way. On the other hand, do you think the typical Head-Fi'er buy new gear that often? IMO, Head-Fi'ers buy new gear here and there, then trade or sell to get new gear. Are speaker enthusiasts able to trade/sell as easily as Head-Fi'ers? Also do...
