Whatever you have. If you don't have anything look up some reviews here, there are pretty good chipamps these days, I'm happy with my SMSL but there are tons of options.
And I would like to get those for my table PC setup
For nearfiled use I'd personally always choose coaxials. KEF Q150 might be within your budget when on sale, but they can't fill anything but a very small room. The DBR62 don't struggle too much with that, but of course all small speakers benefit from a subwoofer for bass extension and SPL.
Get an amp with a subwoofer (or line) output.
If you are on PC just apply room correction with REW, you can use any microphone you have to start but be aware that dynamic mics will roll off significantly at both ends of the frequency spectrum and thus some manual tuning of the response will be required.
The DBR62 have about +/- 20° useable vertical angle which is pretty good for a conventional speaker, and midwoofer and tweeter are not spaced too far apart meaning they sum up at reasonably close range. And they don't look too bad in person either (although no real wood veneer of course). They're really decent speakers without major flaws which is something to behold at that price. As an allrounder they are a good chioce and definitely worth the extra money over Debut 6.2 and similar offerings - those too have their place, but for daily use investing a little more is worth it imo.
