The Audio Note (UK) Conqueror Stereo Power Amplifier is a tube amplifier that uses the 300B triode valve, which is well known for its sonic qualities, as the output tube. This power amplifier is designed as a pure class A single-ended design, which means that it operates in class A mode at all times, even at low power levels. This design is known for producing a very natural, transparent, and detailed sound, but it also has relatively low power output compared to other amplifier designs.

The Conqueror Stereo Power Amplifier is designed to prioritize sonic performance over technical specifications and meets the Audio Note (UK) Level 3 criteria. Some of the key features of the Conqueror that contribute to its performance include the use of pure class A operation, zero negative feedback, single-ended output stage design, valve rectification, which contributes to a smoother and more natural sound, directly heated triode operation, and finally, the materials and component quality used in the amplifier are also important factors that contribute to its performance. High-quality components and materials are used throughout the amplifier to minimize distortion and provide a consistent and natural sound.

The Silver version of the Audio Note (UK) Conqueror Stereo Power Amplifier is an upgraded version designed to further improve the sound quality of the Conqueror Stereo Power Amplifier, providing a more natural, transparent, and detailed sound. The Silver version uses Audio Note Tantalum film resistors. These resistors are designed to provide a more natural and detailed sound compared to standard carbon film or metal film resistors. It also uses Audio Note (UK) Copper Foil signal capacitors known for their ability to preserve the nuances and subtleties of music and provide a more detailed and dynamic sound. Additionally, the Silver version of the Conqueror uses IHiB C-core output transformers, which are designed to provide a wider frequency response and lower distortion compared to standard output transformers. 

The Conqueror Stereo Power Amplifier Silver Signature version is an even further upgraded version as it features several additional improvements compared to the Silver version. Using Audio Note (UK) Copper Foil signal capacitors, Audio Note (UK) Tantalum film resistors, and Audio Note (UK) IHiB Double C-core output transformers, which are designed to provide an even wider frequency response and lower distortion compared to the IHiB C-core output transformers used in the Silver version. Double C-core transformers are known for their ability to maintain a more accurate and natural sound compared to standard output transformers.
