Does anyone have any feeling about the use of equalizers (graphic or
parametric) and the phase changes (distortion?) they introduce?  I'm
about to build a pre-amp that does not have tone controls, so I'm
considering adding an equalizer to my system.  Any suggestions about
types, designs, or manufacturers?

Are there any sources for tone controls as a separate processors?  What
about using parametric tone controls (i.e. only bass and treble but with
variable frequencies)?

I'm also considering buying or building a spectrum analyzer.  Does anyone
out there use a spectrum analyzer in conjunction with an equalizer
(and a noise source) to compensate for the room acoustics?
