I have both HD555 and HD650 and a Shanling PH100 headphone amp.
I've moved to a speaker system for all music and a decent 5.1 for computer gaming...
Sometimes when I play games, I need to use headphones so I have HD555 plugged into my receiver. The HD650 w/ Shanling PH100 amp just collecting dust. Do you guys think it's worth using the 650 over the 555s with the receiver? Should I just stick with the HD555 and sell the other stuff? I don't see myself ever needing to use again really... the speakers are better and more convenient
