Associated Equipment: HP Pavilion Laptop, Windows 10 OS, iTunes version 12.10.2, Massdrop IEMS; Tenz P4 Pro, Ultimate Ears UE900s and Noble X Universal. All of the music selected for this evaluation was ripped from CD’s using the Apple Lossless codec.
Musical Selections: A playlist comprised of Rock, Jazz, Classical, Blues and Electronic music was used for the evaluation of the Zorloo Zuperdac-S.
Presentation: The unit arrived via USPS in a plain white box containing the Zorloo Dac and three USB cables. The Zorloo Zuperdac-S is about half the size of a USB thumb drive. It has a standard USB C connection on one end and a 3.5 mm headphone jack on the other end. There are two volume buttons along the body of the unit and a lighted power indicator on the opposite side.
Initial Set Up: The Zorloo Zuperdac-S was connected to an HP Pavilion Laptop using the supplied USB cable. The Pavilion immediately found and downloaded the driver after which the Zuperdac superseded the internal sound card of the system. An IEM was attached to the Zuperdac –S.
Evaluation: I can confirm comments from other reviewers, the cables supplied with the Zorloo Zuperdac-S are garbage. The cable had to be placed in a particular position to hear anything. If the cable was bumped you lost signal with great amount of crackle and noise. Throw them away and use a USB cable that you already own or buy a new one. A Cosoos 9 inch braided cable was purchased from Amazon for $6.99 and was used throughout the evaluation.
The initial test is always to turn up the volume to 100% and listen for any hiss, hum or noise. In this case there was dead silence.
Next several music selections were chosen from iTunes.
Bass presentation was deep and tight with nice extension. I heard no muddiness or boom.
The midrange was accurate and vocals sounded natural and clear.
The treble was crisp and clear. There was no sibilance or distortion. The Tenz P4 Pro sounded a little bright but then they have that tendency.
The soundstage was as big and full as any that I have heard with an IEM. The imaging separated the instruments and the vocalist quite nicely.
All of the IEM's sounded great bu in my opinion the most engaging performance was pairing the Zorloo Zuperdac-S with the Noble X Universal.
Conclusion: The Zorloo Zuperdac-S is an excellent alternative to the native DAC supplied with most electronic devices. I am very pleased with this DAC’s performance and have recommended it to friends and associates.
Would recommend to a friend.
