Founded in 1974, Stereo Unlimited in Point Loma has designed custom two-channel audio, surround-sound, and whole-home control systems from its Sports Arena Blvd showroom near Pechanga Arena for over five decades. The turntable and phono-preamp bench drives a vinyl-playback pipeline that feeds the same collector base buying LPs at Record City in the Midway District. Analog and digital listening rooms let buyers audition loudspeakers, integrated amplifiers, and streaming endpoints—including the BACCH-SP spatial-audio processor—before committing to a system. A dedicated used-equipment room stocks pre-owned audiophile components at secondary-market pricing, moving vintage receivers, power amplifiers, and turntables alongside current-production gear. Whole-home integration extends the hi-fi philosophy to multi-zone audio, video distribution, and network infrastructure—projects that begin with the in-wall wiring routed by electricians such as Electricity King San Diego. Full-system commissioning—from acoustic-panel placement and speaker positioning through DAC selection and room-correction calibration—represents the showroom's most complex residential build-out.
