Adorned with K2HD Technology and crafted from Japanese stainless steel, the Kensei represents the pinnacle of our refinement in the GO bar range. \nTailored. Sweet Sound.\nListen your way with four bespoke digital filters and two analogue processing modes, each designed to enhance different music genres. Bit-Perfect delivers natural tones, making it ideal for all genres. GTO enhances sound details and density, particularly suited for vocal tracks. Minimum Phase produces a warmer sound, blending the characteristics of Bit-Perfect and Standard, making it perfect for soul and jazz. Standard offers a tighter sound with controlled highs, ideal for pop music and movie OST. XBass+ boosts bass, while XSpace creates a spacious soundstage.\nCompact and Powerful.\nThe GO Bar Kensei, crafted with Japanese stainless steel, offers maximum rigidity in a compact size (65 x 22 x 13.2 mm), similar to a USB flash drive. It’s the perfect travel companion for mobile, tablet, or MacBook Pro users. With USB-C connectivity for plug-and-play convenience, it delivers up to 477mW output power—10 times more than an iPhone 15. It features iEMatch for high-sensitivity IEMs and Turbo mode for power-hungry headphones, effortlessly driving a wide range of premium earphones and headphones.\nCut the Crosstalk.\nConnect to the GO bar Kensei via 3.5mm S-Balanced or 4.4mm Balanced headphone outputs. iFi’s exclusive 3.5mm S-Balanced* technology cuts crosstalk and noise by 50% with regular single-ended headphones.\nAdvanced chip. Accurate clock.\nThe GO bar Kensei’s DAC section features a 16-core XMOS microcontroller programmed by us to optimise sound quality and perfectly complement the 32-bit Cirrus Logic DAC chipset.
