Below are excerpts from the review:
With its balanced design, The TC44Pro E2 is a potent dongle DAC with class-leading resolving capabilities, particularly in complex treble arrangements and textured bass-synth combinations.
It maintains a neutral tonality with little to no coloration, yet it excels in emphasizing details and resolution in the higher frequencies.
In simpler arrangements, the E2 tends to play back both male and female vocals in a more forward manner. Its staging performance may be a little lacking given the listed power output, but it makes up for it with its pinpoint imaging.
