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? _____________________________________________________ "One more red nightmare..."
