Description
The Delta Stereo distills Classé's amplifier engineering into a compact, high-performance stereo component for situations where dual mono amplifiers can't be accommodated. The first 12.5W per channel run in pure Class A, with a total of 250W per channel (over 350W/channel into 2Ω) driving loudspeakers with confidence and exceptional channel separation.
Features
- Up to 12.5W per channel delivered in pure Class A operation
- 250W per channel total
- Massive, high-quality power supply with custom toroidal transformer
- Hand-laid, 6-layer circuit boards for shortened signal and power pathways with lowest noise
- 22 4-pole Mundorf capacitors
- Custom-made Navcom feet to absorb vibrations
- Furutech rhodium-plated RCA and torque-guard speaker connectors
- Custom-designed illuminated VU meters displaying power output for both channels
