Review on 🎧 Sabaj DA3 Portable USB DAC Headphone Amplifier with OLED Screen, SABRE9018Q2C, DSD512 32bit/768kHz by Josh Kim

First, it's very weak and requires a separate amplifier if you want decent volume levels. Second, it doesn't work well with iPhone (can't speak for Android). I tested it with an iPhone 6, 7 and x with the camera adapter turned on and none of them were able to turn it on successfully. The screen flickered on and off. Third, the sound is very cold. Compared to the top nx4 dsd it sounds dull to me and has more noise. All in all I would suggest looking elsewhere depending on your needs. mx3 is a much better desktop DAC and nx4 is a much better mobile DAC/amp combo. I can't say exactly where this DAC can be useful other than its balanced 2.5mm output and its size. Even then it's still overpriced imo.
