The Quest is a line of Pure Class A Single Ended Mono Valve Amplifiers designed and manufactured by Audio Note (UK). These amplifiers utilize a single 300B triode valve per channel, resulting in a level of performance that is considered to be significantly superior to many contemporary designs.

The use of Pure Class A amplification, coupled with the single-ended (SE) design and the 300B triode valve, contributes to the Quest’s reputation for producing a high level of performance achieving Audio Note (UK) Level 3 criteria. 

The Silver version of the Audio Note (UK) Quest Mono Power Amplifiers enhances the already excellent performance of the standard Quest model by incorporating several component upgrades. Including, Audio Note (UK) Tantalum film resistors, which are known for their exceptional precision and low noise characteristics. They provide improved accuracy and stability in the signal path, contributing to enhanced audio quality. Secondly, the addition of Audio Note (UK) Copper Foil signal capacitors to offer excellent electrical properties and contribute to a more transparent and detailed sound reproduction. Finally, Audio Note (UK) IHiB (Interleaved High Bandwidth) Double C-core output transformers, which are designed to provide extended frequency response and improved transient response. These transformers play a crucial role in shaping the amplifier’s output, ensuring accurate and dynamic audio reproduction.

The Silver Signature version further enhances the performance of the standard Quest model by incorporating significant upgrades. The first notable upgrade is Audio Note (UK) Copper Foil Signal Capacitors, which are known for their high-quality construction and exceptional sonic characteristics. These capacitors contribute to improved transparency, detail retrieval, and overall sound quality. Secondly, Tantalum Film Resistors, manufactured by Audio Note (UK), which are renowned for their precision and low noise properties. By using these resistors, the amplifier benefits from enhanced accuracy and stability in the signal path, leading to improved audio performance. Finally, the IHiB (Interleaved High Bandwidth) Double C-core Output Transformers from Audio Note (UK) designed to provide extended frequency response and superior transient response.

With these component upgrades, the Silver Signature version of the Audio Note Quest Mono Power Amplifiers aims to further elevate the overall performance, delivering enhanced sound quality, detail resolution, and musicality. These upgrades contribute to a more refined and immersive listening experience for the discerning audiophile.
