Easy for you to ask. I doubt any store has the device. And the equipment required to amplify .00000000001 dB to an audible level would take up the entire room. There is no such thing as a .00000000001 dB signal Whats stops a .00000000001 dB signal from existing? Nothing, it's just indistinguishable from a 0db signal. In other words it's about half the amplitide of a 3db signal... It's a logarythmic scale. Bye. Jasen |
