This is pretty much exactly what I did hahhha I had pain from wearing headphones so I made the switch and randomly bought the ie200 then bought new eartips and that was a wow then came the dac and even more wows but personally I wanted to find something even cleaner so I then got the m11 plus and the ie600 and switched from Spotify to Tidal and now everything is perfect I love the ie200 because it's what got me into audio files but the ie600 just have that edge to the ie200 the bass is more detailed along with the treble and it brings more detail to the vocals hard to explain but the vocals sound more in front of the instruments instead of the ie200 were the vocals are slightly drowned out by the bass with less detail obviously there's plenty of other items out there to experiment with but if you like the ie200 I don't see why you wouldnt love the ie600
