Guy and I can switch roles this time. The parametric equalizer goes 
between the component that you want to adjust (the module) and the 
final output (amp). If you want to play with one of them, be prepared 
to spend at least a little money. Alesis and Aphex have something in 
the range of $350-$400. I'm not sure whether these units have as many 
as 5 or 6 bands. Others in the higher end will set you back thousands 
of dollars. If you want to include adjusting for standing waves in 
your room, you'll have to work out the affected frequencies by the 
particular room dimensions, diagonals, etc., which ain't easy on 
paper. There is room analysis software out there, and some of the 
better home audio receivers and processors are beginning to use 
something like it to determine surround levels in home theaters. It's 
a brave new world. Keep us informed about what you do.
