From Plus to PRO, I noticed the most improvement everywhere. Imaging turned out to be more 3D, not exactly “holographic” but definitely more 3D, I can pick up each individual instrument with ease, there’s more transparency, everything sounds cleaner and clearer, mid/high resolution has improved as well as the lower frequencies (cleaner/tighter). Inside Ableton Live this made all the difference as it helps me choose sounds easily, have a better sense of what’s going on, due to improved separation and detail, and helps me make better mixing and mastering decisions. I use a high-end audio interface with the greatest DAC’s and clocking and high-end monitors and headphones and even so, there was room for improvement. Every seasoned music producer should use this.
