I don't wear earplugs. If I want to be up front at shows, I generally go in with the attitude that the sound may be spotty. This hasn't always been the case - The White Stripes at the Amphitheatre in '07 sounded killer in the front section. However, historically, the amphitheatre's dead-sounding zones are in various areas of the 200-300 levels. I don't think Toronto has many consistent acoustic-friendly mid-sized venues, not including the new Opera House, Queen Elizabeth Theatre and newly renovated Royal Conservatory and Sony Centre. Standing by the soundboards at clubs and bigger venues is usually a good idea, but even that doesn't always work. I think the Kool Haus is just too cavernous for some some bands to handle. It's all a crap-shoot.
