I'm going to buy new audio setup, but what to buy?

[True Buie]

Heyo everyone!

I've chosen to finally upgrade my audio at home/desktop. I've chosen to go with the Beyerdynamic 770 Pro 80 Ohm's. One of my friends have them aswell, although he's using them with an DAC and AMP, and he says that this will make my sound experience soooo much better. I'm in situation though that I don't what AMP and DAC I should buy.
I'm not really an expert on this area, and that's why I'm asking you guys now. Any suggestions to what set I should buy? I'm pretty lost on this, but I wan't to get the best possible setup
My budget for the DAC/AMP is -+ $150

Thanks for taking your time to read this!
Thanks in advance to anyone who suggests.
