Very good product, simple, effective. I use it connected to a MAC STUDIO with several DAWs and virtual instruments, I wanted a card without frills, without DSP... It meets my expectations. I had bigger, more expensive UAD X6, I didn't hear any difference compared to the use I make of it. One flaw for me, the levels of inputs 5 to 8 are low in my opinion, I would have liked to have gains (not necessarily physical knobs, but at least digital) on the analog inputs 5 to 8 located at the back.
