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.
