Working on a single reference monitor for years creates an anchor that allows reliable mastering decisions

Mastering engineers stress the value of working exclusively on one well-understood monitor system, in one room, for years. The engineer builds intimate knowledge of how that system reveals sonic characteristics — an ‘anchor’ enabling rapid, confident decisions. Switching between different-sounding monitors during a session destroys the anchor and leaves the engineer lost, because each speaker has a different character.

Examples

Glenn Meadows: ‘if I start listening on different-sounding monitors, then I’m completely lost. But on the monitors that I’ve worked on for 13 years in the same room, I know how they sound.‘

Assessment

Why does an experienced mastering engineer avoid switching to secondary monitors mid-session even at a client’s request?
