AMP I Genie Integrated Amplifier Wifi Bluetooth Stream Pre-Amp

SW1X Audio Design™ AMP I “Genie”

Performance Level 1/2
Integrated Amplifier


AMP I is essentially a 2 gain stage Power Amplifier coupled with a High Quality Pre-amplifier.

EL84 power pentodes are known for their energetic and musical qualities being a very popular tubes due to their usage in the guitar amplifers and radious in the 1960s.

The Triode Connected EL84 maintains that musical & energetic sound character plus adds the refinement and drive of our higher performance amplifier range.

Available in different output stage topologies and versions: PSE and the Push Pull (PP) version with integrated Phono (LPX) or DAC (DX) options and different power output transformer options.
