It depends on the size of the bit. I'ts a lot easier to hear a lot
of small bits than it is to hear one large bit. The lowest level is
believed to be 3 teledynes per root Hertz for a little bit.

You can get any resolution you want by using a Cockcroft-Walton type
multipler. Remember, though, that the upper limit will be bondwidth
limited by the package size.

No need to apologize, degression is normal in the morbidly obese.
Getting back to the point, however, any system will be equalized to
the norm if you make sure that your finals are class "C" with
tracking notch filters. It cannot be emphasized enough, however,
(since you have sensitive ears and can appreciate the difference)
that your speaker cables should be 0 AWG fine-grain centrifugally
cast directionally solidified silver clad with at least 251 migrons
of hard gold. It's not generally known, but the gold cladding keeps
oxygen from migrating into the surface of the silver and causing
inverse skin effect, which keeps the high frequencies from
propagating along the outside of the cable, where they belong.

40WRMS means 40 watts Really Mean Service, which is generally
accepted to mean that it's a heavy-duty system meant for outdoor
use. 500WPMPO means 500 Watts P.M. Power Output, and this is
basically a rating for musical instrument amplifiers which are used
at night, when it's cool.

By all means follow the advice given by the "golden eared" crowd.
Since you all have fat heads and sensitive ears the numbers won't
mean/matter much to you anyway, and you'll be more easily swayed by
those in the same boat (barge?) as you.
