Hello, some days ago I bought a new pair of headphones - HiFiMAN HE-400!
I'm now looking to buy an Amp. It has to be better than my current (Asus Xonar Essence ST headphone amp)
I feel like I could use some more bass and I like warm, fun sound.
I listen to Hiphop and Dubstep.
Budget ~300 euro
Feel free to inform me what's good for my headphones, budget, preference and upgrade-worthiness.
Edit: It's gonna stand at home @ my computer so no need portability.
Matrix M-stage may be perfect for you, it has a nice warm sound and plenty of body. You can roll op-amps too if you're looking to adjust the sound. Cost me around 200 euro shipped from China.
