The combination of CUBE with good dynamic headphones gives a lot of fun listening to music. You can feel the power of the headphone amplifier and the quality it offers at a reasonable price. Prodigy Cube in its price range offers a rich, dynamic sound, and its presentation is bright, clear, full of details and fast punctual bass. The characteristics can be changed using a replaceable opamp.
 

SOUND
The sound is rich in colors, the instruments are quite well separated from each other (there is no confluence), the high tones are beautiful and shiny, the vocals are clear and understandable (you can feel the nostril in the voice), the bass is as it should be, it does not come to the fore and it does not play a dominant role, but it is fast, punctual with great dynamics, you can feel its power and where you need to, it can surprise you with its dynamic attack. The whole thing gives a beautiful insight into the recording, you can hear many details and nuances, and the stereo image is beautifully presented. The PRODIGY CUBE works best as a headphone amplifier, and it was probably created for that, because with the appropriate adjustment of the headphones it can surprise with what it can present. It probably does not offer what the Chord Mojo killer does, but let's not compare two different eras and price ranges. The CUBE performs worse as a DAC, it does not offer the compatibility of the drivers with the data streaming standard ASIO (from Audio Stream Input / Output). and support for DSD. 
 

CONCLUSION

Due to the limited possibilities, the described Audiotrak should be classified as a simple, good-sounding external sound card, rather than as a real DAC. The low range of 96 KHz at 24 bits and the lack of ASIO support and support for the developing DSD unquestionably exclude it from the favorites list. It should be mentioned that it is relatively cheap as a replacement for the internal integrated PC or laptop sound card. It offers decent sound quality for those listening to music rather than paying attention to the specs. It can easily compete with similar products from companies such as the well-known PC world: Creative or Asus. Certainly, it is not a gaming product because it does not have the ability to handle multi-channel sound, but in stereo, despite some limitations, it maintains a strong average level.

Audiotrak offers a wide range of audio accessories, including the once appreciated DR.DAC and the well-known inexpensive Prodigy HD2 internal music card. Prodigy Cube is a good alternative if we want to enjoy good sound, and our source is not a desktop computer, but a laptop. Cube is very different from the high-standing Dr. The Dac lags slightly behind the internal Prodigy HD2 card, but it is definitely a good solution as a good headphone amplifier and external sound card for a portable computer. It can compete with the more expensive and well-known Audins HUD MX series based on the same Tenor TE7022L chip and compete with Creative Labs cards. Thanks to the DIP socket for the OPAMP in which it is mounted, we get the opportunity to change the sound characteristics cheaply, and the external USB source, which is the Prodigy Cube, will be free from the pain of internal noise of sound cards.
