The iFi audio GO bar Kensei is a portable USB DAC and headphone amplifier designed to elevate your mobile audio experience. Weighing just 2.3 ounces, this compact device connects via USB-C and features a Cirrus Logic Master HIFI DAC and XMOS USB chipset, supporting PCM up to 32-bit/384 kHz and DSD up to 12.4 MHz. It offers both 3.5mm unbalanced and 4.4mm balanced stereo headphone outputs, delivering impressive power with a balanced output of 477 mW RMS into 32 ohms and an unbalanced output of 300 mW RMS into 32 ohms, making it suitable for a wide range of headphones.
Match your amplifier's power output (Watts RMS) to your speakers' sensitivity and impedance (Ohms). Do not obsess over astronomical peak wattage claims; RMS is the true measure of sustained power. Available from $449.
Amplifiers have practically zero ongoing costs aside from electricity, which is highly variable based on usage volume and class type (Class A uses more power than Class D). Good amplifiers can last decades with proper care. Consumables are virtually non-existent unless using tube amps.
Common Failure Modes
Solid-state amplifiers are extremely reliable. Failures usually stem from blown capacitors, overheated output transistors, or physical wear on volume potentiometers. Proper ventilation prevents 90% of heat-related failures.
Match your amplifier's power output (Watts RMS) to your speakers' sensitivity and impedance (Ohms). Do not obsess over astronomical peak wattage claims; RMS is the true measure of sustained power. Class D amplifiers run cool and are compact, while Class A/B offer traditional warm sound at the expense of heat and size.
Solid-state amplifiers can last 20+ years. Capacitors may eventually dry out and need replacement.
