I’m using a focusrite Scarlett as a dac just because I already had it. You don’t necessarily need a dac but if you’re plugging into a pc for example there’s a lot of electronic noise on the motherboard dac that an external dac won’t have

I don’t plan on upgrading for a long time

After debating on spending quite a big chunk on headphones I pulled the trigger and bought the hd6xx and little dot mkiii as my first set of real headphones and amp a couple of months ago. I can’t believe I spent years listening to music on crappy gaming headsets or stock apple earbuds and didn’t know how bad it was. This setup has been my most used possession since I bought it and I can’t wait to continue listening to more music with it.
