The high output power of 1300 mW + 1300 mW allows the amplifier to drive hi-fi headphones with ease. The three gain levels and volume curves allow the listening experience to be adapted to headphones and earphones with different impedances. The timeless, slim design of the K11 R2R allows for flexible placement. The high-quality display shows all relevant information.
