The Black Magic 20 stereo amplifier is the perfect blend of form and function and the ideal choice for serious music listeners. It is conservatively rated at 20 watts per channel in stereo mode and 40 watts in monoblock mode. This stereo amplifier offers outstanding performance that is difficult to believe, with a high impedance input, an automatic DC restorer and bias circuit for each channel. Output tube idle current is very low, which greatly increases tube life. It has ultra-wide bandwidth output transformers with interleaved windings capable of the most nuanced voice as well as huge peak output capacity. From a listening perspective these amplifiers provide a warm, rich sound with a sumptuous and enveloping sound stage, a great front to back depth of field, and very tight, pinpoint imaging within that larger acoustic. A special current feedback circuit allows the amplifier to "listen to the room" via feedback from the speakers acting as microphones (using the law of reciprocity). The room-speaker-amplifier interaction provides a sense of believable ambience and acoustic space that is thoroughly realistic and quite enjoyable. Additionally, the transformer output impedance allows the signal to follow the impedance curve of the speaker system, allowing more voltage to be delivered to the loudspeaker at very low frequencies - providing an exceptional and satisfying low end response.
