Hi, adi, its me again. I need to correct something I said in the previous missive. I said a doubling of the volume is equivalent to 10db. This is incorrect; Danny used the correct figure of 3db. It still applies that 3db is what occurs when someone turns it up a little; because our hearing is logarithmic, larger and larger changes in volume are required for us to perceive a difference. Strange but true, a sound measuring 120db is 12,000,000,000,000 times louder than one you can barely hear, so if your ever tempted to tell a friend that your system plays a million times louder than his, you probably on safe ground! Luck...Jeff
