25Wrms / channel class AB single-ended tube hybrid power amplifier
|
This is one of our state-of-the-art hybrid power amplifiers that combines both the advantage of a transistor amps high current drive (tight bass and good speaker control) and single-ended vacuum tubes amplification (warm and sweet sound with good depth, sound stage, and air). The transistor output stage of the standard version is a voltage to current converter circuit without any NFB or voltage gain, so the non-linear sound of transistors can be greatly eliminated. Left behind is the high damping factor that can controls the speaker more efficiently. The tube section is working in an optomized single-ended operation mode in order to achieve the purest and most natural tonal quality.
