My relatively conservative Grado SR80 headphones have served me well over the years. I've been interested in buying something new, primarily the Sennheiser HD 650.
If I buy the HD 650, I also want to run it through a desktop amp. My question is, will having a hi-fi headphone powered by an amp be detrimental to my hearing versus a simpler, non-amped headphone? I am always keen on preserving hearing and I don't listen to music overly loud.
