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 have been using copper beading cones inserted into copper end caps. The former are really hard to come by lately. You need to do a Google search. The latter can be had on Ebay. Since I have never used SR's HFTs I cannot comment on how they compare. All I can say is that if you find the right positioning the results can be very impressive with a DIY version of SR's HFTs. I have over 70 in my system -- total cost about $70 vs. $4,200 for 70 SR HFTs. How's that for getting a bang for your audio buck?
Adding mass to smaller speakers, like exercise plates on top.

Blankets, pillows and tapestries can be useful experiments in room acoustics. Pillows especially around the speakers and on the floor, bean bag chairs, etc.

Best,

Hey Sabai thanks for the DIY transducers. I'm using 14 with good results.

 I read about this one on Analog Planet, the use of turnbuckles. between your rack and back wall. I bought 2 pieces of threaded rod and 4 nuts and the results were not subtle. The best $5 bar none!
Everyone here has heard about using the Magic Eraser as a stylus cleaner ( use scissors to clip a 2mm triangular wand off of every corner of the block and then use it to flick the stylus back-to-front like a stylus brush).

You can also use the Magic Eraser to polish/de-oxidize spade lugs, speaker terminals, tube pins, male xlr contacts and male AC plugs... without any harsh chemicals. You can see it is polished, i don't have the patience to do before/after listening tests.
Happy Ears
