100Wrms / channel single-ended tube  hybrid power amplifier

This is one of our state-of-the-art hybrid power amplifiers that combines both the advantage of transistors (tight bass and good speaker control) and vacuum tubes (warm and sweet sound with good depth, sound stage and air). The transistor output stage is a voltage to current converter circuit without any NFB or voltage gain, so the non-linear sound of transistors can be eliminated. Left behind is the high damping factor that controls the speaker more efficiently. The tube section is working in an optomized single-ended operation mode. If you were unaware this was a hybrid amplifier and you judged the sound quality by listening only, you would believe it was a pure tube power amplifier.

The upper picture model shown is an enhanced deluxe version with an extra KT88 as an intermediate driver stage. This gives the sound a fuller and much richer quality. True balanced inputs are also available as an option.

The red MDF chassis model is an enhanced power capacitor version with an input level control option.

The gold Aluminum chassis model is an enhanced tube version with add-on 6550 as power driving tubes.

The Black oak chassis model is a Balanced input version with add-on EL34 used as power driving tubes and volume control.

The lowest picture set is a 3-input integrated amp version with a black piano finish.
