In general I think a trial and error approach without benefit of math can get kind of expensive. The tweak you are suggesting seems harmless enough and shouldn't cost much more than a little time (always in short supply )!

Keep in mind that I don't doubt you hear a difference. However, you probably shouldn't be so sure that other people will also hear a difference unless you've used a little more rigor in your testing than just your own observations.

I don't think you will find much outrage here as you will a healthy dose of scepticism around sound 'enhancement' claims. Perhaps this is the case because there are so many science/INTJ types here.

It's all good as long as you're happy with the results.
