About the SE84CKC Set

The Decware SE84CKC Zen Triode Stereo Amplifier is a Class A single-ended triode amplifier designed for audiophiles who appreciate simplicity and purity in sound. It delivers 2.3 watts per channel into 8 ohms, using a minimal signal path with only six parts in the audio circuit, including 2 EL84/6BQ5 output tubes, a 6N1P-EV signal tube, and a 274B tube. The amplifier features zero negative feedback, point-to-point wiring, and Decware's proprietary UFO wide bandwidth output transformers. It is stable down to 1 ohm loads and is optimized for high-efficiency speakers (minimum 89 dB sensitivity). The SE84CKC has a frequency response of 20 Hz to 20 kHz, input sensitivity of 2V, and supports speaker impedances from 4 to 8 ohms. It includes two analog stereo inputs, a front-mounted volume control, and top-mounted switches for input selection and bias setting. The amplifier is hand-built in the USA, weighs 17 lbs, and measures approximately 8 x 6.125 x 12 inches. It comes with a lifetime warranty to the original owner and is recommended to be left on continuously for optimal tube life, which is about 5,000 hours. The design emphasizes a Zen-like utilitarian aesthetic and sonic purity, making it a cult classic among discerning audiophiles who pair it with efficient speakers such as Klipsch RP-260f. The SE84CKC is the successor to the original SE84C and is noted for its detailed, revealing sound despite its modest power output.
