I have the 900 pro or whatever they’re called with 250 ohms and they run perfectly fine from my pc. If I had them louder I’d probably get hearing damage. Is there really a big improvement with an external dac?
That depends what kind of soundcard your PC has. For example some MacBooks feature a DAC with support for high impedance headphones. Most „standard“ PCs don’t have a very good soundcard, so you would definitely benefit from using a DAC. Maybe not from a volume level standpoint, but with regards to audio quality.
