My ex needed some speakers when we split and she got her own place. I recommended Edifier (available for $100-$500 on Amazon, etc.), and really enjoy them for the price when I've been over. They have amplification and a dac built in and can connect to your computer via bluetooth. Different models have additional connection options (usb would be ideal for your situation).
I read about Edifier here and all the positive things people had said were true.
