ASR Mini Basis Exclusive HV

Phono preamplifier for Moving Magnet (MM) and Moving Coil (MC) pickup systems. The technology of the “small” ASR phono preamplifier Mini Basis is installed like all ASR amplifiers in a housing made of high-quality, slightly transparent acrylic glass.

A variety of adjustment options through input resistance and amplification allow any pickup to fully play the inherent sound qualities.

Not least due to the elaborate power supply, the ASR Mini Basis sounds very dynamic, with a very powerful and controlled bass. The sound image is of precise spatiality and associated with a very good detail resolution.

The sound is typical as for ASR products, very relaxed and unobtrusive.

As with the emitter, many additional customer requests can be realized in the area of equipment.
