re. grilles on or off, i tried very diligently to enjoy the sound with grilles on for each model of harbeth i have owned. the sound was overtly soft compared to other speakers i like. grilles off sounds excellent with no negatives really.
the idea that amplifiers sound the same if at the same volume is also something i simply have not witnessed.
