About the 28K
The Aragon 28K is a remote control preamplifier designed with advanced features and military-grade components, including Tiffany gold RCA connectors. It uses a fully discrete Class A circuit from input to output, with matched transistors operating as a single transistor to create a pure and simple signal path. The design eliminates output coupling capacitors to provide deep, controlled bass without phase shift. It includes an encased toroidal transformer power supply to reduce noise, laser-trimmed rotary potentiometers with motorized remote control for volume and balance, and dual outputs for biamping or headphone driving. The unit is highly regarded for its neutrality, transparency, and dynamic sound, offering performance beyond its price point and is sought after by audiophiles. It is made in the USA and weighs approximately 21-27 lbs with dimensions around 19 x 11 x 3.5 inches (44.5 x 38 x 16 cm).
