I've found I have a little spare cash burning a hole in my pocket right now and figure I might as well upgrade my audio setup a bit. Currently I am running digital from a PC through USB to a Schiit Modi, then analog into a 1976 Sansui 331 Stereo Receiver, and finally out to a pair of Beyerdynamic DT990 Pro 250 Ohms.
I like the way it sounds but feel it could be better, and the Sansui occasionally drops the left channel which is a bit of a pain. I'd like to upgrade it with an amp that's a bit more modern, and I'd like to give tubes a try, though I know nothing about them. Bonus points if the amp also has outs for a pair of speakers, and even better if it has a switch for turning the speakers on or off but I know this is a stretch.
My listening habits are mostly edm, hardcore, and math rock.
Alternatively I would also be willing to invest in a new set of cans if that would get me better performance per dollar.
Budget is ~$200, up to $250 if necessary. Thanks!
