It sounds like a rhetorical question, and perhaps it is. For as much as you can read about any other piece of gear in a hi-fi stack, you read and hear very little about pre-out software equalizers. I've been using them for a long time and they can improve _any_ stack or headphones I've thrown at it. The degree of the improvement, of course, highly depends on how good your gear is -- or, said another way, it makes great gear even better. Am I not looking at the right forums/websites? Are they perceived as net-negatives by the rest of the community? Or it a matter of lack of awareness?
