10 Best Tube Preamplifiers for Audiophiles

These devices are designed to amplify weak signals from audio sources, such as turntables, CD players, and streaming devices, to a level that can be processed by power amplifiers and speakers. Tube preamplifiers are known for their warm, rich sound, which many audiophiles prefer over the more sterile sound of solid-state preamps.
