Mine are pretty closely matched but I bet if I was able to somehow label them precisely, I'd find a slight difference as well. Same thing with the NuForce HA-200 in monoblock mode. It's basically the nature of a potentiometer to have slight variation from one to the next - even for really nice ones. This is why I prefer to use DAC volume control (or a preamp, if that better fits your system).
