Once you get past the setup (which can be a headache if you're on M1), this interface performs exactly how you would expect.
The sound quality is great, with low noise levels and true sounding output when ignoring the unison preamps. The controls on the hardware are easy to use after the initial learning curve.
The onboard DSPs are super useful for zero latency tracking, you just have to be careful not to max them out. Certain UAD plugins hog the space quite a bit, so I recommend removing any tracking plugins after you're done with them to make room for others when you're mixing.
Overall great product, only con is the initial setup and slight learning curve for the UAD software. UAD plugins themselves are high quality and sound amazing. The included plugins are more than enough to get you started.
