Okay, I listen to my ipod nano with typical "junk files". I simply don't have the time and energy to upgrade my 1000+ song collection to 320 or lossless at this time. Maybe a couple years from now when my newborns are older and I have some free time. Looking into "upgrade" or just something different from my Grado RS60i powered by FIIO E6. Just something better or more fun to listen to. Budget $100-$500 Sennheiser Momentum Sennheiser Amperior Beyrdynamics DT1350 or "Forget it dude stick with your Grados, not worth the effort or money with crap files"
