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!

geoffkait,

In my system Franck's basic diagram works very well. Franck eliminated a lot of the guess work for me. YMMV.
So, anyway, has anyone played around with 1/2" diameter bowls? Just curious....

Two things improved the overall sound quality dramatically. I re-terminated the speaker cables, replacing the spades with the locking banana plugs. (if your amp has some fancy binding posts with a large contact area for the spade you don't to need to). Another thing I did was to move the speakers away the back wall. By the way I noticed that the OP started this thread 16 years ago. Wow.

   Just a quick note on the Franck Tchang placement. I was really not expecting much.....HOLY CRAP!! was I WRONG! The soundstage opened up in height, width and especially depth. Vocals were so much clearer. I do have a fairly revealing system, so others results may vary, depending on their gear, but this is one cheap tweek everyone should try. About 3 hours of labor including research, pick up of supplies, installation and about $20 out of pocket, yielded what I would consider a $1000`s worth of improvement!

Who knows, if you had used a SPL meter instead of a rough guide you might have considered it a $3000 worth of improvement. When you don’t place the tiny little bowls precisely on the sound pressure peak you wind up with a local maximum. If you’re off by 6" you can miss the peak entirely. Hel-loo! In addition, Franck Tchang points out that the recommended locations are intended for HIS resonators, I.e., the locations are specific to his GOLD, SILVER and PLATINUM resonators, depending on location. Which IMHO is all the more reason to look deeper into the placement of whatever resonators you’re using. For example, Franck Tchang writes,

"Step 4 should only use the Silver or Gold Special models. This position is very effective to open up the corners. The wooden base must be installed on the sidewall but butt right up against the front wall. It should sit slightly lower than the center resonator of Step 3 but no lower than 5cm from the ceiling."
