iBasso Audio can't stop and won't stop loading Cirrus Logic DACs into their sources. DC07 Pro is their latest balanced 4.4mm dongle supplied by a quad of CS43131 DAC chips from the DX180 music player, working controlled by iBasso FPGA-Master technology.
It's landed right on Headfonia's Recommended Buys list. DC07 Pro's state-of-the-art decode flows onto a fully-balanced analog path counting on common-mode rejection and claiming 134dB of signal-to-noise ratio. Audiophile-Heaven have added it to their Hall of Fame.
An OLED screen basically adds to the illusion of music player levels of detail and fidelity even from USB's 5 volt supply are possible with DC07 Pro. A thoroughly regulated circuit and clean power form the basics here, as with every iBasso.
It's solutions like DC07 Pro that continue to see USB DAC/amps raise their game. Further pushing decoding precision is an outboard clock that means DC07 Pro does not rely solely on its USB receiving chip for a master clock, but its FPGA. [See Product Desc. For More]
Said FPGA sees DC07 Pro overachieve by supplying its CS43131s DACs the same pure I2S as iBasso's bigger DX180 and DX260 DAP alternatives, pushing down DAC phase noise and jitter for a stable decode.
After decoding, iBasso's generous use of negative feedback quashes distortion and claims up to 134dB of signal-to-noise ratio.
The employment of this feedback also sees DC07 Pro achieve bandwidth that's effectively flat from 10Hz to 75Khz. That means phase reproduction in the audible human hearing region is perfectly preserved, for the totally realistic portrayal of dynamics and natural transparency – a triumph of iBasso's budget DAC dongle.
Powerful op-amp output buffers can supply nearly one watt of power. iBasso's little wonder promises high power and damping factor while maintaining its low distortion into low impedances typical of IEMs, Focals, Fostexs and Rosson Audio Designs.
Still the closed-loop internal gain remaining after the application of negative feedback around DC07 Pro's op-amp IC analog circuit remains high. So where she really shines is in swinging volts, opening up the sound of any high-impedance Audio-Technica, Sennheiser and ZMF Headphones while barely breaking sweat.
The quality of DC07 Pro's signal will translate to nearly everything you choose to drive from its balanced 4.4mm output, or 3.5mm – turning it into a miniaturised DX180, if you would.
Flying the dongle DAC/amp flag high is DC07 Pro, till you turn to iBasso Audio's DC Elite here and other upgrades here, or others in our catalogue here.
