I have Ultrasone Pro 900 headphones (40 ohm impedance) and am going to buy an amp because I want:
- more overall volume
- better / stronger / more impactful bass (very important)
- better overall sound quality
- a good looking amplifier that fits nicely on my desktop
- to spend less than $300 (looking for good value)
I have been considering the following amps:
Hi-Fi Man EF2A Tube USB DAC Headphone Amp - $169
Little Dot MK III Headphone Tube Amplifier - $244
Q-2 Tube Amplifier - $99
FiiO E7 and E9 combo - $180
Considering these amps, their prices, and my headphones (Ultrasone Pro 900), which do you think is the best? I don't want to spend too much money, but I also don't want an amp that won't considerably increase the sound quality. I don't have a DAC, and I'm currently listening through on-board sound on my desktop PC. I think I'll be happy with either tube or solid state amps although I like the look of some of the tube amps. I listen mostly to metal and bass heavy electronic music. I'm totally new to amps and have no technical understanding of them, so I would highly appreciate any advice. Thanks!
