I mainly listen to lossless music through my ipod or laptop connected to sr 60s or m50s. I'm thinking of upgrading to the 225s. I'm terrified of tinnitus, so I usually listen at half the volume or below and that's plenty for me. Given that I don't need extra volume and i use low impedence phones, what benefits would an amp provide? Would something like a total bithead be worth the expense?
