Optimized Tuning

ddHiFi's 4.4mm balanced DAC dongles have gone through the first generation TC44B, the second generation TC44C, and now the current TC44Pro with its sound tuning once again optimized further. The brand-new internal wires and soldering make the tuning orientation more balanced, and the alignment of digital plugs and analog sockets has been further streamlined.

True Balance via Dual-DACs

The TC44Pro features dual Cirrus Logic CS43131 DACs. And for a more stable signal-to-noise ratio and dynamic range, the mainboard is symmetrical and designed without openings. Furthermore, the headphone and USB sockets are manually soldered with silver solder.

Carbon Fibre Panel

The back of the TC44Pro is covered with a special 1800D carbon fibre panel. This flexible and lightweight carbon material has a low coefficient of thermal expansion and high thermal conductivity, effectively protecting the internal PCB board.

Pro-level Craftsmanship and Thoughtful Features

The TC44Pro features an integrally formed aluminum alloy shell, and the wavy surface reflects the delicacy of the new PRO-series titanium color.

It also comes with a leather lanyard that's not only a good decoration, but also allows you to easily carry the device and avoid losing it.

The TC44Pro's helpful indicator light keeps you alert of your current track's output quality and type:

  • Blue: PCM output
