Hello. i have Xonar DX on my pc and bought Denons ah-d2000 cans. I found out that Xonar is to weak for it. I am mostly a gamer, playing bf3 with 6-channels on and dolby headphone. If i get a Amp+Dac to it will i loose this 3d effects or what? What about an amp only? 
Thanks

Impedance is resistance, measured in Ohms.
You want the impedance of the headphone to be at least 8 times the impedance of the headphone jack the headphones are plugged into.
 
The Xonar DX headphone output jack has a high impedance (100-Ohm?) and your AH-D2000 are only 25-Ohms, that is the cause of the audio problem.
So you need to get an external headphone amplifier with a low impedance, like 3-Ohms or less.
 
O2 (Objective 2) portable headphone amplifier, $155, impedance is something like .5-Ohms, works fine as an ac powered desktop amp.
 
Fiio E11 portable headphone amplifier, low impedance, like .5-Ohms, for $61.99 you can get the E11 with a spare battery (BL-5B) and a simple battery recharger.

So E11 wiill not change any sounds effects channels which sound card produces? Will just better drive headphones?

Correct, sound effects will not be negatively affected and your Denon AH-D2000 will sound way better.
You might want to leave the E11 on the low voltage and low gain setting to conserve battery power.
You can also get a few extra batteries (BL-5B) off eBay, the OEM ones from China may not hold as much of a charge as rated (mA),
but the price is so cheap, they are still a good value.

Thanks a lot. Is there any similar quality/price amp but with ac or usb power?

If you switch to a USB connection, like the Fiio E10 (USB-DAC-Head amp.) you lose most of the features of the Xonar DX, like Dolby Headphone surround sound.
An external add-on amplifier that is AC powered and has a low impedance just cost more.

Thanks! Going to buy it after payday.
