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 controls the speaker more efficiently. The tube section is working in an optomized single-ended operation mode to achieve the purest and most natural tonal quality.
If you were unaware of this amplifiers construction, and you judged the sound quality by listening only, you would believe it was a pure tube power amplifier and not a hybrid.You can then have both the smooth and silkyness of single-ended sound with very good punch, rich and controlled bass.
Upper photo set is for standard version (C$1,680), mid photo set is budget version (C$1,380) built with additional dual volume control pair(optional C$100) , you can choose to use either 6922x2 or 6SL7/6SN7x2 (optional $80) when placing the order
Second to lowest photo sets show the budget version with 6SL7/6SN7 upgrade
Lowest photo sets show an ultimate integrate amp version with 6SL7 + 6L6G plus upgraded power supply
Balanced input version available with additional cost
