The Sennheiser HD-600 work best (and I am pretty sure were designed to work) with a headphone amp. I had been using Grado SR 60 headphones and just recently upgraded to a HD-600/Creek OBH-11 amp combination and I find the combination quite good. I am recovering from spine surgery, so the headphones are getting a good workout.
One observation is that well recorded CDs benefit from using a headphone amp. Poorly recorded CDs sound just sound louder and worse.
