### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Awesome combo for the money
  

*by B***N on Reviewed in the United States on September 18, 2023*

This DAC AMP combo sounds awesome! Smooth and transparent. Plenty of power for 99% of headphones. The only issue I had was with crackling in windows even with the SMSL drivers installed. They need to figure that out. Random crackling sounds on 2 different windows PC's. Other than that, this unit performed excellent in all regards. Hope they update the drivers soon for everyone.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Great detail but....
  

*by P***R on Reviewed in the United States on November 2, 2023*

Coming from a Schiit Audio Gungnir DS version I sold it and bought the DO300ex based on the new AKM chipset 4499. The 300ex is a good dac with great detail, air, separation and bass slam but after a week my ears are hurting, and the overall sound doesn't seem natural to me. The unit lacks soul and emotion to me so I just returned it. I hope this helps your buying decisions. I'm still on the hunt for something new but in the interim my modi multibuilt OG works perfect for now.Happy Listening,
