This is my first stereo compressor. I have been slowly acquiring gear for my home studio as it is my goal to get out of the box and more into the analog domain. My reasoning for getting out of the box is that I find myself paralyzed by too many options via plug-ins. I just want to make a decision and move on. Since I own no other stereo compressor, I do own a 6176, it is difficult to give a fair comparison. But I can say, without hesitation, that purchasing the 2500 has increased my productivity, inspired me to use my gear more, and increased the quality of my recordings. I am so inspired that I just ordered an API 5500 to boot.
