Of course **I** can hear the differences in preamps !
**I** can hear the differences in sound that accrue from the slight magnetic anomalies as the Earth wobbles on its rotational axis !
But most people can't. That is why i urge blind tests......preferrably in a magnetically-shielded, zero-gravity, anechoic chamber.
