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!

lexphin,

I'm very glad to hear you are getting such spectacular results -- like me. Franck Tchang did not create his guide out of thin air. He is the original master regarding resonator placement. Everyone else followed him. Of course, variations and adjustments may further refine things. But my experience is that he got this dead right. Your experience reinforces my feeling that his placements are a good place to start -- and possibly to finish.

geoffkait,

Have you actually tried what I and lexphin are reporting here with Frank Tchang's placements using DIY resonators -- and then tried out your own theory to compare? Or is this all just speculation on your part? With all due respect, it is one thing to quote Franck Tchang for the sake of debate. It is another thing to talk from your personal experience. Since you said in your post, "Who knows ..." may we assume that you do not know from your personal experience and are just enjoying the debate?
No need to be snippy, Sabai. I started designing and selling acoustic resonators before acoustic resonators were even a gleam in Franck Tchang’s eye. That’s why I know that a SPL meter is the only real way to determine where resonators should be placed in any room. Now, I'm not saying that using Franck Tchang's diagram won't work, it will. It will get you around 50% of my SPL meter method.

have a nice day

Now, if you opt to do ALL of the above.....

Cups, tile, bricks, sandbags, BB's, metal plates, floor braces, et all...

Your gear will resemble a construction site that needs 'tidying up', and edging towards my 'steampunk' speakers' in general appearance.

Please post pictures....curious minds need a good laugh. ;)
