👎 Cons
- The "reference class" status and advanced features suggest a higher price point, which might be prohibitive for budget-conscious home studio users.
- Being a tube microphone, it typically requires a warm-up period before optimal performance is achieved.
- The need for an external power supply and specialized cables (not explicitly mentioned as included) can add to the setup complexity.
- The microphone's sophisticated controls and multiple polar patterns might present a steeper learning curve for novice users.
- Its large diaphragm design, while beneficial for sound, may require proper acoustic treatment in the recording environment to prevent unwanted room reflections.
