The iBasso DC-Tonfa is an 8-channel R2R dongle DAC/amp designed for desktop use and condensed into a dongle form factor. It incorporates a 24-bit, 8-channel discrete R2R architecture in a portable size. Using 8 R2R channels in a truly balanced, fully differential configuration, it achieves vanishingly low distortion and improved linearity at low levels, preserving the musicality that makes R2R so beloved while delivering detail and performance that surpass traditional R2R designs.

Features:

• Compact size with authentic R2R appeal
• 312 high-precision metal-film resistors — three times as many as in typical R2R dongles
• Resistor network made up of 312 matched metal-film resistors, stabilized at low temperature
• Resistor correction network with 60 high-precision resistors
• Precise resistor-tolerance control through FPGA software algorithms
