ASR MINI BASIS EXCLUSIVE HV

High-end phono preamplifier designed to deliver excellent performance even in a compact form. Its architecture integrates carefully selected components such as ultra-fast ICs, high-capacity 200,000 µF electrolytic capacitors, and ASR Magic Cord power cables, ensuring a stable current and extremely clean power supply, essential for precise and controlled musical reproduction.

The preamplifier’s design combines the best of the analog and digital worlds, with high-fidelity differential circuits that achieve low noise, minimal distortion, and exceptional dynamic range. Every detail is engineered to enhance the musicality of vinyl, providing deep and controlled bass, clear resolution of subtle details, and a stable soundstage.

The Mini Basis Exclusive HV features a phono input optimized for MC and MM cartridges, with selectable impedance and capacitance settings to accommodate virtually any cartridge. Users can adjust gain and loading via internal DIP switches, allowing precise calibration based on the type of vinyl and cartridge sensitivity. The output is available in traditional RCA configuration and optionally as a balanced XLR, offering versatile connectivity to high-end amplifiers and audio systems.

The chassis is made of slightly smoked transparent acrylic, a material that minimizes resonances and unwanted vibrations while allowing a view of the meticulous internal construction. Solid brass heat sinks and a carefully laid-out circuit design further contribute to stable, interference-free signal transmission. Users can personalize the front panel with chrome or gold lettering and choose WBT Nextgen RCA connectors in copper or silver.

The Mini Basis Exclusive HV is the result of ASR Audio Systeme’s expertise, a German company with over thirty years of experience in phono equipment design. This preamplifier represents a “mini” version of the celebrated Basis Exclusive models, transferring much of the flagship’s sonic quality into a more compact and accessible package. While some features such as battery operation and dual fully independent inputs are omitted, it retains refined musicality, with rich, natural mids, deep and controlled bass, and engaging dynamics.

The Mini Basis Exclusive HV is ideal for vinyl enthusiasts seeking faithful and detailed reproduction, suitable for living rooms, dedicated listening rooms, and high-end installations. Its compact size and moderate weight allow easy placement without compromising quality. The attention to materials, German engineering, and high-quality components make the ASR Mini Basis Exclusive HV one of the most refined and reliable solutions for modern vinyl listening.
