DD ddHiFi TC44C

ddHiFi TC44C Review

ddHiFi’s latest USB dongle DAC-AMP is announced today, the new TC44C.

Acoustically, dual-channel balanced.
TC44C has dual DAC chips Cirrus Logic CS43131 for decoding, which provides better SNR, dynamic range, signal range of the audio source, distortion and fidelity. The 3.5mm, 4.4mm and USB-C ports are well arranged in a straight line despite their different sizes.
OCC copper internal connection line
The headphone socket, especially the 4.4mm, has many pins, so opening holes on the circuit board may seriously affect the circuit’s wiring. The circuit board design of TC44C simplifies the wiring by separating the socket from the mainboard. Moreover, OCC copper is for connection and lead-free soldering tin with 3% silver for soldering.
Shell craftsmanship goes one step further
Exquisite frosted metal with a rounded waist for a comfortable grip. There are no assembly gaps around the headphone sockets, which are susceptible to electromagnetic interference. Also, the thick bottom cover shields the USB socket thoroughly.
The concealed LED indicator
The transparent 4.4 mm socket can transmit light to indicate the status: Blue indicates PCM output, and green indicates native DSD decoding output. However, when the 4.4mm socket is plugged in, the light will not be visible.
Provided OCC copper USB cable
ddHiFi provides a high-quality OTG decoding cable named TC05 in the package, released and sold separately on the market. The cable is made of high purity silver-plated OCC with Teflon and TPU double insulation. The plug is integrally formed, which is sturdy and durable but also ensures high-quality sound.
Limited leather case
ddHiFi also prepared a limited quantity of 600pcs genuine leather case with hand stitching as free gift.
