In fairness, I feel I should give an example of how this might play out:
You load up the new software update, but when you listen to the favorite presets you have been using, they don't sound very inspiring (too bright, too dull, too much gain, too little bass, etc). So now you set about tweaking these presets, and sure enough, they end up sounding much better! The hard part is knowing if they really are better than before, or if you are just wowed by the before & after comparison, or if your own tweaking skills have improved enough to have made a significant difference. This is in no way to minimize all the amazing work Cliff and the Team are doing (free of charge, no less) ~ Only to say that the differences/improvements are harder to recognize/substantiate when the 'playing field' has been somewhat re-arranged.
