ASR Mini Basis – Phono Preamplifier

Description The ASR Mini Basis is a high-performance phono preamplifier engineered to deliver reference-level analog playback in a compact and elegant form. Designed and handcrafted in Germany, this precision-built unit combines the sonic excellence of ASR’s larger models with a minimalist footprint ideal for any hi-fi rack or audiophile setup. Supporting both MM (Moving Magnet) and MC (Moving Coil) cartridges, the Mini Basis features adjustable gain and impedance settings via internal DIP switches, allowing fine-tuning to perfectly match your cartridge’s characteristics. The result? Exceptional tonal balance, dynamic range, and low noise floor. Its standout feature is the advanced power supply design: a robust 72 VA shielded transformer, ultra-fast Schottky diodes, and over 200,000 μF of filtering capacitance. This ensures steady, interference-free power delivery for cleaner, deeper sound. The transparent acrylic chassis not only reduces resonance but also showcases ASR’s meticulous internal layout and attention to detail. Whether you’re spinning jazz, classical, or modern pressings, the Mini Basis reproduces your vinyl with startling realism and emotional depth. Ideal for audiophiles seeking maximum flexibility, high-end performance, and understated visual appeal, the ASR Mini Basis is a true gateway into the world of ultra-pure analog playback.
