Turn your equipment on a couple of hours in advance; start your listening session after midnight; listen in total darkness (except for the glow of the tubes, if any) - which may mean putting electrician's tape over annoying indicator lights; and eat a bar of chocolate at the beginning of the listening session.
Know of a "Dirt Cheap" tweak?
I am looking for tweaks to improve the overall sound quality of my audio system. I recently purchased some TPC contact cleaner and it made a believer out of me. I noticed a signicant improvement, as if a veil was lifted my system sounded more clear and transparent. Bass got tighter too. Do you know of any cheap tweaks that have made a SIGNIFICANT improvement to the sound quality of your Hifi system...let us know... :-) Comments welcomed!
