Hi Head-Fi ...
I have a Beyer 990 250Ohm, for desktop listening with a laptop. I'm comfortable with a below-$300 budget. I listen to electronic music which are bassy, using a 1964 Quad on the go.
My friend uses a GoVibe Vulcan with his 990. From looking around Head-Fi I've seen suggestions like:
Modi + MAgni
There're so many DAC/Amp options I'd very much appreciate some help!
