Winner of 2010 Excellence Award by AEx
BLO-0299 is an audiophile quality headphone amplifier which is housed in beautiful natural wooden box. Its compact size is excellent for desktop use. BLO-0299 can drive balanced headphone (also two single ended headphones). Balanced headphone listening provides a more natural, musical, and detailed sound with great stereo imaging.
The BLO-0299's Integrated circuit was designed to provide great detail and clarity. The circuit design is clearly better than even the best discrete designs. High quality metal film resistors are used, no electrolytic capacitors are in the signal path. All passive parts are hand selected to provide close matching and even the solder used is high grade. BLO-0299 has achieved ultra low noise and distortion, very flat frequency response, and great phase property. The BLO-0299 was designed for true musical tone.
