Alpha 6 It is a power amplifier 100 pwatts per channel into 4Ω, characterized by a wide frequency response from 10Hz to 50kHz and a signal-to-noise ratio of 100dB, guaranteeing silence and sound detail even at high volumes. This separate configuration allows for optimal control of the audio chain and reduces electrical interference.romagnetics between the pre-amplification section and the power stage. The damping factor of 50 The Alpha 6's precision control ensures precise speaker control, while low distortion and high dynamics make this pair ideal for those seeking authentic yet powerful vintage sound. Perfect for hi-fi systems with moving magnet turntables, modern digital sources via an external DAC, and medium-efficiency bookshelf or floorstanding speakers.
