"it's interesting. nobody has endorsed an equalizer. why ?"In my case an equalizer constricted the soundstage, even when in the bypass mode. I had it modified such that the bypass mode now emulates a hard wire connection, and the soundstage degradation is no longer audible for me--IF the equalizer is in the bypass mode. I'm told (by Duane, a dealer friend of mine) that the only equalizer that didn't degrade the sound was the Cello by Levinson, but it was priced at 14,000 dollars.
