• 【All-in-one DAC & Headphone Amplifier】Multiple digital inputs: USB, coaxial, optical, HDMI-IIS, XLR,etc.for versatile connection.Outputs:RAC,6.5mm monitoring + 4.4mm balanced output, compatible with mainstream HiFi headphones.for versatile connection.
• 【Flagship Decoding Chip】Adopts high-end ESS ES9039PRO flagship DAC+8X OPA1612 op-amp,and the XMOS-XU316 USB chip, supporting 768kHz/32bit, DSD512,SNR 140dB,DNR 140dB,THD -125dB.
• 【4.4mm balanced + 6.35mm monitoring headphones output 】The Kaiboer DAC-K7 features the Matrix Power headphone amplifier architecture, achieving an astonishing output noise floor of <3μVrms. 4.4mm balanced output can easily adapt to headphones with impedances from 16Ω to 800Ω, with a maximum undistorted power of 1000mW@16Ω/23mW@800Ω, delivering clear, stable, and powerful driving force.
• 【Stable dual-band WiFi 6 + Bluetooth 5.1 for high-fidelity audio transmission】Natively integrates mainstream streaming protocols such as DLNA, AirPlay 2, TIDAL Connect, and Spotify Connect.Qualcomm QCC3084 Bluetooth module,Most mainstream HiFi apps can stream to the DAC-K7 decoding output.
• 【Ultra-low noise,Deep-sea level tranquility】Two studio-grade linear power supplies, combined with a voltage regulator matrix and a self-developed Silencewave 2.0 architecture, achieve ripple below 20μV and microvolt-level noise suppression, allowing for accurate music reproduction in a pure and quiet environment.
• 【Windows-Specific Driver】With a customized Windows-specific driver, unlike ordinary universal drivers for DAC equipment, the DAC-K7 is compatible with mainstream Windows systems (Win7-Win11). After connection, a dedicated pop-up window appears, and the brand is displayed on the system desktop, allowing users to achieve long-term stable compatibility with PC-HiFi or professional audio monitoring.
• 【Dual femtosecond crystal oscillators, professionally designed for different sampling rates】Two independent femtosecond crystal oscillators, 45.1584M and 49.1520M, respectively cater to the 44.1kHz and 48kHz sampling rate families. This results in more stable clock precision, purer signal transmission, reduced harshness and dryness common in digital audio, and a warm, transparent sound with clear and realistic imaging.
• 【Sturdy metal chassis effectively reduces electromagnetic interference】Kaiboer DAC-K7 features an all-aluminum chassis enhanced by CNC precision machining and anodized finishing, delivering unparalleled product texture. Equipped with a 4.3-inch LED color screen, it can display function scheduling, spectrum, audio sampling data, and real-time dynamic VU meter. Volume adjustment is available in dB levels, supporting 0.5dB, 1dB, 2dB, and 3dB. Unlike conventional encoders, it supports both knob and remote control volume adjustment.
