My personal experience is that it is a small percentage of consumers that like truly flat sound. If you flatten out a room, it may sound too “neutral” to them.
If you go back to two channel days, the bass/treble/loudness got considerable tweaking.
If you belong to any two channel vintage groups now, and you see pictures of systems with graphic equalizers, they will almost always have the “smiley face” adjustments in play.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
