It's generally reccomended that you spend more on your cans than your amp and dac. I would say to refrain for the bursons and instead grab the JD's labs atom it's an amp that rivals even $1000 amps in how clean it sounds. As well as grab a dac like the topping d10 or d30 or if you can find a grave design sdac go for that. What kind of music do you like and what do you prioritise in sound? Is it voices , little minoot details , spalshy highs? Or big boomy bass.
