exquisite sound experience
Aura ALPHA RIAA
AURA Fidelity's RIAA is a technological splendor. Separate MC and MM input. No noisy switches, and no op amps, only analog circuits with discrete components.
In MC mode, the actual pick-up works in MASTER mode. It directly controls a specially designed circuit (HEAD_AMP) where the coil energy is multiplied by 20. This circuit is supplied from a "phantom power supply". The MC one is, in practice (not loaded) 100k for earth. The result is an incredible dynamic with a soft and natural musicality. Noise is minimized to an absolute minimum.
The MC / HEAD-AMP roles can be easily changed if desired.
It must be heard - to read the spec. is not enough.
