You may have misunderstood. I was saying it is important for anyone to play with DSP to understand the difference it makes to educate themselves on different sound profiles and the impact of frequency ranges which will help them understand what they want, buy accordingly and avoid GAS. Using DSP to "correct" a system wasn't what I was trying to say, that is another topic. I also don't believe in using DSP to "correct" issues unless they are severe, my approach is to use DSP to shape sound to preference. Essentially what many companies do is flavor the sound, that is what I think DSP should be used for, instead of being stuck with the sound the company made, you are free to experiment as you please. I don't agree that DSP should be used just for the bass, I think people who say this are either lacking in experience/knowledge of DSP or they have a product to sell such as expensive speakers, where if one would flavor with DSP to achieve similar results, their product would loose interest.
You are right, to each his own.
