I've done some research, and I think the SRH1840 will be a great match for me. A lot of people will say otherwise and they are usually said to be avoided for rock and metal, but I'll explain why. I also want to point out that I will be using these for gaming a lot, so these being good for gaming is very important. I want a big soundstage for imaging and powerful bass to make for a fun experience (lots of bass will give emphasis to explosions and such). While the LCD-2 will have an excellent bass for gaming, it's soundstage is said to be poor which is a problem for me.
First off, these are said to lack bass which is one of the reasons they are not recommended for rock/metal, however, there is a mod which improves the bass (along with better imaging, timbre, and balance) by a lot, and if done properly, it won't bleed into the mids. It isn't permanent so I can just mod it again if the bass is too much. It's mids are said to be great, and even comparible with planar mids. It's treble is said to be very detailed and airy and it's soundstage is said to be great.
To sum it all up:
-excellent mids (Good for guitars and vocals)
-detailed and airy treble
What more could I possibly want for rock/metal + gaming? What are your thoughts? Please feel free to suggest a headphone that be even better in case there is one. My budget is 1000 dollars.
