Editorial Reference
Model context
Position within the Cary range
Fully balanced valve monoblock from the Founders Edition line, featuring three class modes (A, A/B, and B) and 845 output valves.
Why choose this model?
When high-power balanced monoblocks with three selectable class modes are required, surpassing the SET of the CAD-805RS.
For which system does it make sense?
- Reference systems with balanced monoblocks and selectable operation modes.
- Demanding loudspeakers requiring up to 150 W per channel in Class B.
- Installations where the range name "211" identifies the FE series, not the output valve.
Differences compared to similar models
Greater power and three class modes compared to the CAD-805RS SET. The CAD-211FE employs 845 output tubes despite the "211" in its name, according to the official documentation.
Architecture and Design Decisions
Fully balanced monoblock from the Founders Edition line featuring two 845 output tubes, two 300B driver tubes, a 6SL7 input tube, and a 6CA7 in the power supply. Three modes: Class A (70 W), A/B (110 W), and B (150 W).
Compatibility and Use
RCA inputs (100 kΩ) and balanced XLR (200 kΩ). One block per channel; balanced preamplifiers recommended.
Official specification limits
The "211" in the name refers to the series, not the output valve (845). Do not confuse it with the CAD-805RS SET, which delivers 50 W.
