yep! i've got a k5 kicking around on my desk, a proper dac is good stuff. they've still gotta make one we can cram 60W through though!
ed: i guess i should add that i just use a pair of bluetooth cans or even bone-conducting set when i am listening to stuff from my phone 'cause it's just podcasts and youtube videos
I bet it’s better to just have a product like this compared to a smartphone headphone jack with a run of the mill DAC:
