Korora

Korora MM/MC Phono Stage Amplifier, with passive RIAA Filter
Standalone solid-state battery powered phono stage preamplifier, equipped with a built in recharge circuit and high performance Ni-MH batteries. It can be used on battery power alone (recommended), or while charging. The Korora has an extreme high S/N (close to -100db) performance when powered with the battery.
Firestone Audio Engineering centre has made big efforts to get he Korora at the stage where it is now. At lonely hight, and can be compared to units that are much higer in price !
