I'm currently looking for a pc-fi solution for SRH1840 to listen in my dorm(Also has a pair or HD600 but I probably only use them for classical music).
the budget for the entire system excluding USB cable and headphones is  around 2500$.
Mostly listen to J-rock like NICO TOUCHES THE WALLS, metal like NIGHTWISH(not much, I consider their piece a bit too soft for me...), Slipknot and Halloween. Some Jazz piano, and some bit of Eric Clapton unplugged...
Prefer a slightly-heavy, more dynamic, deep bass(not a big amount of bass),a mild mid, and a textured high frequency.
The things I'm looking now Is 
Schiit Gungnir with Ragnarok or something
The lyra2 or callia from Prism sound
meridianprime(My high school audiophile classmate suggest me to buy this, however I don't even know where to buy them lol)
 
Dac+amp all in one is preferred since I will live in student apartment. If possible I also don't want to use a heavy power source unit like these in RSA Raptor.
BTW how did full size amp users find price for their equipment? I searched for Prism sound lyra2 and callia in their official website but didn't find a price but only a dealer locator, they say There's only one universal dealer in china but my friends told me there are some authorized resellers who get authorized products from this dealer. I just got totally confused...
Same thing happened to meridian prime but this time when I search for it I only got reviews but nothing about official webpage and price...omg...
request you help guys... I'm a bit messed up about my first set of non-portable stuff...
