The Infinity F.E.T. Preamplifier was a notable component in the audio landscape during its time. It was characterized by its innovative use of field-effect transistors (FETs) which contributed to its performance and sound quality. Users appreciated the design, which was considered ahead of its time and distinguished by a certain aesthetic appeal. Many audio enthusiasts reminisce about its capabilities, often comparing it to competing products like the Audio Research line. Despite mixed initial reception, the F.E.T. Preamplifier has retained a degree of nostalgic value among vintage audio collectors and enthusiasts. Some highlights include its efficient amplification and low noise operation due to FET technology. The preamplifier was designed to deliver clear and transparent audio, catering to audiophiles seeking high fidelity in their sound systems.
