I'm tired of the Astro Mixamp, so I want to buy something as a replacement. I've been looking at the ASUS Xonar Essence One, but it is quite expensive, so what other opportunities to I have?
I'm using a laptop. I am looking for a device with really good sound quality and the option to connect microphone (for better mic. quality instead of what my laptop greats) is a must.

What sources are the MMXs going to be plugged into?
Win PC? Mac? gaming console?

  Unfortunately, I'm using it on a laptop, and the amp is not available in Denmark :frowning2: But thanks for the answers though.

Audio-GD NFB-15.32 DAC/Amp, 190 Euros + shipping

I've had my 15.32 for almost 3 weeks, does a nice job of driving all my headphones
EHP-02D, DAC/Amp, 190 Euros + shipping
Comes USB and line-input
A FiiO E10, USB/DAC/Amp, price?

  Can I also connect my microphone to those devices?

They do not come with a line-input for microphones.
But you can still plug a microphone directly into the laptop or get a USB microphone.
I would assume a decent quality USB microphone would offer better audio quality, over plugging a microphone directly into the laptops line-in/microphone jack

I fail at reading comprehension, your using a laptop. You should look at the asus u3 and a good headphone amp.

Thanks a lot, is the U3 for microphone only or what effect does the headphone amp have that I need if I buy the u3? 
If the U3 is for the microphone only, what quality will it give me? I know that the Beyerdynamic MMX 300 has a high quality mic, so I want to use its potential.

I inferred, maybe incorrectly, that you would be using this for gaming. I recommended the U3 because it would give you dolby tech, and would be a good place for the mic to go, and because it is a great value. I was recommending that you use the u3 for your mic/dac and have it feed a decent amp. If you dont want dolby headphone for gaming/movies, I would just get a decent headphone amp and call it good. You will probably need a cable extension for your mic in either setup. 
So to summarize : Laptop's usb->Xonar U3 (provides dolby headphone, and a good mic input)-> headphone amp.  In this scenario you would plug your mic into the U3 and your headphone into the amp. This is pretty versitle because in the future if you want a better DAC you can feed it through the U3's optical out and still retain dolby headphone. 
2nd option if you dont need dolby headphone: Laptop Line out via -> amp -> headphones. 
You might also look into the Asus xonar essence u7, and the creative line of external sound cards that will be a tidy all in one solution. These would have enough juice to do your headphones justice. 
Something to consider, since you already have a mixamp, you could just buy a better headphone amp and feed it from the mixamp.

No problem, once you get the U3 in hand, you will see how to hook it up. Pretty useful piece of kit for ~30 bucks.
