Below are excerpts from the review:
As the name implies, the ddHiFi TC44Pro is a step up from the smaller TC44A, leaning more toward the TC44C territory, the basic A version.
While the A version only comes with a single DAC, the Pro one enjoys the same dual CS43131 chipset, seen on the higher-grade TC 44C. The same architecture found in olds-but-mighty AstellKern SR25MKii and Cowon’s Plenue D3, two great players, sonically speaking.
As you’d expect, you get better dynamic range, enhanced SNR and lesser distortion, leading to improved performances overall, thanks to the dual-channel, balanced circuit. On paper, we should get better performance than the previous models, with enough power to drive moderately hard to drive headsets, like the Meze 109 Pro, or planar IEM like the Letshuoer S12 Pro..
