Hi Poppa,
What you noticed from that vocal session is where I basically keep my levels, 
for the last 13 years using PT.
I've gotten very good results keeping it up there.
I will admit you half to be very diligent while running levels up there!
Heres some further clarification of the level discussion from my "design 
Engineer" friend.

>From tom Graefe
"My ANALOG console  has a dynamic range greater than any Protools system.  The 
-20 dB standard by Sony I set for the SDDS system I designed.  The -20 dB is a 
reference for a nominal sound pressure level when mixing motion pictures.  It 
allows 20 dB of headroom for the loud passages and a nominal sound pressure 
level to be the same in all Theaters.
If you gave this guy some real test equipment and show him how to run it he 
would be surprised how foolish he really is.  I have a $20,000.00 Audio 
Precision test set.  If you run an IMD  (intermodulation Distortion, a 4 to one 
mix of 60Hz and 7KHz) at -1dBFS and then do the same at -18 dBFS  the IMD can 
be up to an order of magnitude higher.  Your Buddy has no idea about how 
Digital audio or A/D converters work.

Later

So in conclusion!
You can record at any level you want, that will determine the "LEVEL" of 
quality you get!
I always refer back to the Creator for the real story!
Your Signal to noise ratio mileage will definitely vary! :)
