Anyone else find Neumann KH 120 II fatiguing for arrangement work (not mixing)?

Used KH 120 V2 daily for 3 years, 5+ hours a day, both mixing and arranging in Logic Pro. Great for critical mixing — neutral and accurate.

But during arrangement specifically (adding layers, picking tones, building ideas) I get fatigued fast and lose motivation within 45-60 min. The analytical sound makes everything feel less exciting creatively — every flaw is so exposed that it's hard to just enjoy a tone early in the process.

3 years in, so I doubt it's an adjustment thing.

Anyone else dealt with this? Did adding a warmer second monitor (Focal, ADAM, etc.) for arrangement actually help, or is this more about listening levels/habits?
