Seems like many agree there is a difference. What made me ask is that I bought a Canadian copy of Pink Floyd's Dark Side of the Moon awhile back. Although it seems to be in excellent condition, the sound does seem to be on the overly warm and boring side. Bass is a little out of control. Wasn't sure if it was just me or what. Decided to pass on buying more Canadian classic rock records. (no offense to Canadians!!!)
