Well maybe "sound signature adjustment" instead of equalization ? As far as i know the different treble, midrange and bass adjustment on my speakers are done by leading the signal trough 3 different type cable paths with a jumper.Although I understand the message, I think we should reserve the word "equalizer" to devices that change in a measurable way the frequency response. IMHO cables do not act as equalizers and no equalizer can reproduce the action of a cable in a system - they act in very different ways.
The same for room acoustics.
Curiously my system is using all Mogami signal cabling for today - 2791 and 3103. What types are you using now?
