Our favorite reviewer quotes:

  • "My first tube experience is a success thanks to the GR40. It provided such a unique, warm and rounded sound that is unlike anything I've heard." (https://audionotions.com/fosi-gr40-review-from-a-first-time-tuber)
  • "This kind of sound is so refreshing to hear after all the samey dongle DACs and amplifiers littered in the market and provides you with a sound that you might not have heard before on your favorite headphones." (https://audionotions.com/fosi-gr40-review-from-a-first-time-tuber)
  • "Arguably the strongest sonic feature about the SK02 is how much it improves the dynamic range of the headphones I plug it on. The nuances in music, especially when listening to higher resolution files are evident with how the nuances are more prominent and the space in between instruments make music sound more immersive than other sources that I've tried." (https://audionotions.com/fosi-sk02-review-the-best-under-100)
  • "The MC331 expands the soundstage, creating a greater sense of openness and depth while enriching both male and female vocals. This added character enhances the overall presentation, making instruments and voices more engaging and organic." (https://primeaudio.org/fosi-audio-mc331-review)
