The Korora is a battery powered phono pre-amplifier, equipped with built in recharge circuits and high performance Ni-MH batteries. The Korora enjoys an extremely high S/N (close to -100db) performance when powered by the battery, which is the recommended method of use. The Korora can be used with either moving magnet or low-output moving coil cartridges. It utilizes a whole new creative and innovative passive RIAA filter. Switches allow the selection of capacitive load, gain (51, 54, 58, and 69db), and resistive load (10 ohm, 43 ohm, 100ohm, 47Kohm and one free spot).

Circuit Design: OPA2227 for main amplifier, current boosters NPN/PNP power transistors
Class Class AB / DC amplifier, coupling capacitor less
Output Resistance: Extra low output resistance (Zo < 0.05 ohms),high current capacity
Frequency Response: 6Hz~300Khz ,-1dB at 32 ohms loading, very low noise -110dB (A)
Max. output: 6Vrms external gain control switch
The Cute II BATTERY is a high end headphone amp that compliments any digital front end. Connect it directly to your CD player, laptop, iPod, MP3 player or other portable device and experience detailed, dynamic sound.
