The sound of the UD-384 is really impressive. It is extremely transparent, detailed and involving. The amount of resolution and detail it manages to extract from a recording will leave you breathless, it will bring you closer to your favorite recording, every thing snaps in to focus with greater accuracy, you'll hear those little details you never noticed before. What's more the UD384 does all this at a price point that is normally only achieved by much higher priced converters.

 

It's small, it's beautifully styled, and the most important thing...it sounds brilliant, what are you waiting for?

Soundstage:

What surprised me about the Kingrex is the spacious and well layered soundstage. Just before receiving the UD384, I acquired the Audiophilleo2 which I have been using with my reference DAC, the Audio-gd dac19dsp. The AP2 was already an improvement in the soundstage department in comparison with the previous transports I was using (namely the Battery powered Jkeny MK1 and the tweaked A-GD DI).

But the UD384 (with the UPower in place) was definitely better in the soundstage department. While it was perhaps not as wide as the AP2 + A-gd DAC19DSP, it was definitely deeper and more layered. Along with the Beyer T1, the soundstage was gigantic (in certain tracks) and there was still a pinpoint accuracy.

Though, I should probably mention that the soundstage was much better at 24/96 sample rates and higher than it was at the RBCD 16/44 frequencies. The UD384 belongs to the class of converters that can benefit noticeably from upsampling. While some might view as a negative, I personally view as a positive since it allows the end user to try out different upsampling modes for different "flavors" and results.
