"I was used to mixing in the box, and I knew my way around it. You always need to make more room. I realized I wasn’t doing that anymore, and was not needing many of the tricks I used to do to get closer to what I was hearing in my mind, so I wanted to learn how much headroom I got. I fed my converters with the hottest signal in the center of the panorama and started automating the faders around it. Soon enough, the magic happened: the summing box started purring like a happy big cat and I knew that was the sound I always struggled to reach, the famous and legendary “warmth and openness of analog” I so many times read about. "The analog sweetspot".

          
Why No A/B comparison tests?
Every studio setups are different, different mixing strategy, different style, sound and production, can't reproduce Your studio environment,  your studio setup, your monitor type, sound, preamp, amp, gain adjustment, cable, and etc..etc...
