It is important to understand that, in ultrasound applications, it is generally best to have as much gain as possible within the circuit; a wider dynamic gain window allows the amplifier or system to better handle signals with a wide dynamic range. Contrary to popular belief, dynamic performance is not a function of power output; rather, it depends on the extent to which each stage within the circuit’s gain window limits dynamic signal peaks. However, because the gain is so high, the power amplifier’s sensitivity can lead to issues with the background noise floor.
All Audio Note™ power amplifiers feature silver-plated RCA inputs and speaker terminals, with output impedances of 4 and 8 ohms.
Although full-power amplifiers have low output power, their ability to drive speakers—even those with very low efficiency—naturally limits the playback volume; however, speakers with an efficiency of 86dB can still be used, even in smaller rooms.

Peter Qvortrup, proprietor of Audio Note UK, maintains that analogue sound remains superior in our digital age. ANALOG technology possesses unparalleled capability in rendering subtle nuances and delicate resolution. Perfection in sound cannot be achieved through multiple sampling or pitch control. The lost details within music cannot be compensated for by digital technology. All apparatus is handcrafted from the finest materials to each client's unique specifications. Delivery times for appliances are 3-4 months following order placement, which is considered acceptable within this category. We appreciate your patience and understanding. The grade markings on the equipment facilitate straightforward system selection. While it is not essential to pair appliances of the same grade, selecting appliances with significantly differing grades may prevent you from fully enjoying the advantages of higher-grade components.
