Perusing pro-audio magazines, books, and web sites it appears that the qualities searched for in a monitor include (1) accuracy (2) resolution so as not to miss flaws (3) reproducible settings when working with the same monitor in another setting and (4) lack of fatigue - so that one can work for many hours.
classical label monitors
Does anyone know what monitors are used by classical music labels such as Harmonia Mundi, Linn, DG, EMI, Decca, Pentatone, Chandos, and the inhouse label that produced MTT's Mahler cycle? I know that Telarc uses ATC but I have not found a source for what these other labels use.
