7,14,or 20dB. The result is accurate and perfect signal amplification, free from
colouration and yet highly adaptable, the ideal for outputting to power amplifiers.
A separate high-performance power supply unit further guarantees an
interference-free working condition. Panasonic FM electrolytic capacitors stand on
guard along critical paths with their dedication to extremely low ESR. Both the
preamp and the PSU are housed in all-aluminum chassis. A special feature is the
sliding door on top of the preamp opening up to phonostage settings: MC(moving
coil)/MM(moving magnet) with high/low gain and 6 pre-set resistive loads.
Boasting impressive full frequency range with THD as low as 0.0005% and dynamic
range better than 126dB, the PREference will be the chosen one for discerning
audiophiles.
