I just need a desktop dac/amp connected using usb. Yes. I just need to be able to connect my headphones to my computer and hear them clearly. Since without an amp/dac I can barely hear anything and the sound quality is horrible.
How loud do you want to listen to your headphones? That is important to figure out and in the end only you can do this.
Buying from a seller with a good return policy lets you test at home.
Your headphones are not that difficult to play very loud (I’ve the dt880 Edition 250 Ohm that is similar for loudness). Headphone output into around 20 mw for 300 Ohm worked very well for me for most of my listening unless the source was quiet or very dynamic, or I wanted to listen loud. For me around 100 mw was more than good enough and that is ca 6 dB louder where 10 dB louder is considered as twice as loud perceptually. A doubling of power gives you 3 dB more loudness.
There are a number of excellent DAC/headphone amp combos that have 100 mw into 300 Ohm but they cost more than $100 and more around $200, but far cheaper than an audio interface.
For this I recommend going to audiosciencereview where many of those devices are measured along with user experience.
