Lehmann Audio Decade Phono Stage
The Lehmann Audio Decade is a superb phono stage that fills the gap between the Black Cube SE and Lehmannís reference phono stage. The Decade consists of two identical cases, separating the audio section from the power supply, providing excellent isolation and superb audio performance.
Featuring passive RIAA equalization between two linear gain stages, discrete Class A output stage without global negative feedback, PWX II (with supply outlets for two audio sections) and front switchable gain and soft bass roll-off filter this is a serious piece of equipment that needs to be heard to be fully appreciated.
- The passive filter network between two linear gain stages realized with high precision MKP caps (Epcos)
- Several resistive and capacitive loads as standard
- Front switchable gain (36dB - 66dB) and soft bass roll-off (6dB/oct. 40Hz)
- Onboard slot for custom impedance
- Zero global feedback Class A output stage technically identical with the highly acclaimed Black Cube Linear.
- High-quality gold-plated PCB mount RCA connectors for audio.
- Neutrik connector with gold plated contacts for supply connection (as with the Silver Cube).
- Faceplate anodized aluminium - black or silver
