Mad Scientists Audio Nano Tweaks

My dear Audiophile friends...My curiosity has drawn me into trying many crazy tweaks to try and nudge a hint of better sound out of my system. Obviously nothing can substitute for actual quality components so that's a given and on that front I've put my focus. HOWEVER, if using a marker to blacken the center and edges of my CDs helps I'm in. (And yes it does help, double blind test) So from boutique fuses. system disks, upgraded power cords, to Nano disks, if the item isn't too expensive and provides money back guarantee, I'm willing to be a potential sucker. Two issues, well three, come into play. Placebo effect, change of tone misinterpreted as improvement, and volume consistency while evaluating. We all grasp the meaning of the placebo effect. The second issue is much more subtle. A change in the sound which brings out different unheard details when actually nothing is improved overall. You may like the change when your stale music collection can sound new again. There is a value in that.  Then the problem of volume. I caught myself turning up the volume beyond my usual level (DB meter is key) when I was evaluation a new items. Playing louder will obviously allow you to "hear" more within the music. These factors can easily bias a reviewer. Third day after installing multiple Nano things at key spots around my system and I hear #1. a difference which does not seem to be merely rearranging the tone but truly improving the sound. #2. At both high and low volumes enhanced clarity is undeniable. #3. The placebo effect "appears" to work without regard to cost of said "snake oil." My theory is placebo effect works infinitely and without regards to cost. therefore one can "perceive" improvements in the system Curiously this placebo effect often works on visitors who have no knowledge of the "enhancements"!  Therefore I highly recommend Mad Scientist Audio tweaks. Very inexpensive and appears to trigger full utilization of placebo effect! COST? $100
