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.

Ordering
We do not recommend purchasing a key system component without first auditioning it carefully, which is why we have demonstration rooms and a flexible home loan policy.
However in certain situations it can be difficult for people to get to our showroom and for those instances we can offer our mail order service.
