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!

You can home in on the very best locations for almost any type of acoustic resonators like the tiny bowls or even tube traps using a SPL meter and a test time of say 315 Hz off one of those test CDS. This will allow very accurate placement of the resonantors where there are peak sound pressure levels that are say, 6 dB above the average sound pressure in the room. For example, in the upper room corners and first reflection points. You would be shocked at just how many of these exceedingly high SPL peaks there can be in a room. Oh, and don’t forget other rooms of the house.
lexphin,

Copper is good. There are also silver cones but they are not easy to find. Franck Tchang's placement is perfect in my system. I would be interested in knowing your impressions. SR uses crystals under the screen. Audio-Magic copied this in their bells, but with no screen.
Hi Sabai
    Yes, they're copper. I followed Franck's placement as close as I could, my room is a bit asymmetrical. Have not listened with this position, will report back with "perceived" changes. 
Any extras you can put on other components and tweaks. I have them on DAC, transport and other devices.
lexphin,

You were lucky to find them. Are they copper? Franck Tchang's placement is mandatory here. Google Franck Tchang acoustic resonators placement. This will take you to the page on his site with the diagrams. He is the master. Everyone else followed him.
Sabai,

I got the cones from Joann's a local craft shop, the end caps from a plumbing  supply shop. For placement I followed  Synergistic Research suggestions. I will look into Franck Tchang too. Thanx for the tip
lexphin,

You're welcome. Glad to hear. Where did you source the cones? For placement you need to follow the diagram on Franck Tchang's site. This makes a big difference.
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
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!
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,

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?

Use teflon tape (plumbers tape) to wrap around the outside end of power cords iec’s. This will make the iec a tighter connection and may also provide some damping.

You can make your own HFTs for about $1 each instead of buying them from Synergistic Research for $300 for a 5-pack. HFTs are actually resonators, not transducers.

$4.99 at Party City. Much more if sold here.

It appears my decision not to offer Mr. Spock Ears prosthetics for audiophiles 25 years ago was somewhat premature.

Kasboot - here’s a few tweaks...

PHONO CARTRIDGE TWEAK:
I epoxied a brass plate to my Denon DL103 Cartridge. It increased the mass of the cartridge which improved the compliance match to the arm and resulted in superior performance - best $12.50 ever spent.


http://image99.net/blog/files/category-denon-dl-103.html

I probably wouldn’t try this on a real expensive cartridge - but the Denon is reasonably priced and i wouldn’t trade it for anything - so resale is not an issue.

However - I did the same thing with a Denon 103 rebuilt by Soundsmith and the performance improvement is incredible - again, I will not be selling this cart either :-)

ISOLATION FEET TWEAK:
I make my own isolation feet by epoxying a ball bearing to a washer, then add a layer of Sorbothane between the washer and the component foot - works great on the granite isolation plinth - cost about $20 for a set of 4

ISOLATION PLINTH TWEAK
I make my own isolation plinth using a piece of MDF and some rubber drawer liner - but I just upgraded to a piece of granite in place of the MDF to improve the dynamics and looks - cost around $30 each

OUTLET REPLACEMENT:
I use Pass and Seymour MRI grade outlets everywhere - they are affordable, clamp like a vice, non magnetic and extremely good at transferring power

Just a few of the more "affordable tweaks" on my web site

This is pretty much a free tweak.  Put your audio equipment device or interconnects into the freezer for 2 hours.  Then move to the fridge for 1 hour (slow cool down).  Then take out and let it sit for at least 5 hours to allow any condensation to dry.  What this does is additionally solidify the solder points and allows for a closer/tighter electrical transference.  Since there is less resistance over the solder points, it can also allow some components of electronics to run slightly cooler.  I have found additional resolution and soundstage from this treatment.  Keep in mind that since you are changing the metallurgy of the components somewhat, you would want to burn in the electronics again for at least 20-30 hours before making any judgements on the sound quality.

Non-solder components like speaker cable can have a subtle improvement by extended freezing (like 3-4 days).  It's somewhat akin to a poor-man's cryo treatment.

@rodman99999 I still remember starting this discussion many-many years ago at the meet of Chicago audio society (hope I am not the only one from that meet who is still drinking'n'smoking) and the general consent was Yellow Pages on top of each box. I bought a bunch of Shakti Stones, they look better on top of my Naim amps and power supplies (better than Yellow pages I mean) but in terms of sonics - shoot me! I cannot return them so they stay
Some decades back VPI was manufacturing what was called a Magic Brick by many(their DB-5).   Nothing more than transformer laminates, inside a wooden box.   I still have a pair atop the power transformers of my Cary monoblocks, which cause an obvious(not at all subtle) focus of my system's imaging and sound stage, which isn't too shabby to start with.    If you can find them, they're popular and costly.    Whether one ascribes the benefit to them attracting magnetic flux(away from circuits) or damping vibrations(by their weight), or both- they DO improve performance.   Similar benefit can be achieved by obtaining simple steel BBs and filling plastic boxes with them.   Placing these above and below components, especially digital devices, will make a wide variety of changes(both improvements and detriments), so- experimentation is KEY!    The OP wanted, "Dirt Cheap" and this fits the bill: ( https://www.amazon.com/Silver-Zinc-Plated-Metal-4-5mm/dp/B01E9JUGU6/ref=sr_1_9?ie=UTF8&qid=14811... )  &  ( https://www.amazon.com/Maymom-Plastic-Hinged-Crafts-Jewelry/dp/B00ZNPWR4E/ref=sr_1_6?ie=UTF8&qid...  )   There are bigger boxes available of course and in some instances, more weight/more steel is beneficial.
KAVAKAT1  be a man and fight for the dedicated listening room: its your house!! When I was younger I could do it, not any more :-(    Thats why you see headphones and portable CD player next to my "sweet spot" Big'n'Loving family successfully neutralizes all the benefits of my hi-end rig...
The cheapest one I know of was mentioned (I think) by Stereophile: take your glasses off. Works only for the eyeglass wearers of course, but for the "lucky ones" it provides an extra benefit of Total Immersion into music. You wont be able to read/text/surf, only music! Goes well with "Immersion Box" sets by Pink Floyd ;-)
Last week was lube time for my TTs.  This time used 5w30 Mobil One Synthetic.  It might be expectation bias but I like what I hear.  
Plus you get to spend time in the narrow confines under the house, where, I assure you, no one is going to come and bug you. 

Completely agree with Kavakat1. Reinforcing my subfloor from beneath the crawlspace has been on my to-do list for some time now. Finally got around to it a few weeks back. I'm very pleased with the results. I cemmented 3 pillar blocks with 4X4 attached to the joists. Additionally I reinforced the joists by screwing 2X4 on each side butted up to the subfloor. Maybe overkill, but now my system sits on a much more solid foundation, close to a solid slab of concrete. Total cost was approx $200 in materials and 8 hrs. of labor.
If your home has a crawl space or basement, placing supplemental support by way of jacks under the floor where your equipment rack, your speakers and subwoofer(s), if you have, are, will clean up the sound, especially the bass in my case (Vandersteen 2wq). Tightening  up the vibes thru the floor really cleans it all up. Did the laundry room at the same time  to even greater reduction in noise and transferred vibrations. And to a pleased wife.  I have a crawl space that runs from 3 ½ to 4 ft high. My jacks  from Home Depot ran up to 3 ft adjustible placing 4jacks, two with 4x6 beams across the spans between joists, and the other two just straight onto the joists. Total 4 hours start to finish and about $150. Home Depot had everything. Jacks ordered online and delivered. 

Take some Blue Tac or some similar putty and make a small ball with it and put it under the edges of various circuit boards in our electronic equipment.. This sort of adds vibration control and damping and can be easily removed.
Drill holes in refrigerator for cables and place all electonics on racks inside. Support refrigerator with springs to isolate the while kit and kaboodle.

Mass. Adding weight to woofer enclosures may help definition. Bricks on top, whatever you have handy. :)

Especially good for 2 and 2.5 ways with the woofers closer to the tweeter than the floor.
MY wife re-arranged the furniture in her cathedral ceiling sun-room.

What a tweak! Now it sounds exactly the way it should!

There is now a rattan sofa between the OHM Walsh speakers along the wall and fairly close to corners that is 70% windows. Imaging and soundstage has improved dramatically.

She did this of course for reasons other than sound quality but stumbled onto a good sound tweak in the process.

The OHMs continue on Auralex subdude platforms which is key for taming the bass resulting from floor interactions in that room which is tile over suspended plywood floors, a sonic disaster to start with.

What a woman!
Good go Blake: Now you make me want to tweak my tweak as I just used peel off stick on tile that I found behind the fridge when having linoleum installed. I need to power eveything down to work on my cabinet in a couple of weeks and will try it on my CAL player this time instead of the cheap mini system and let you know what happens. The CAL is somewhat brick like already, but you never know til you try. I like the carpet tape, which should be pretty easy to remove and clean off with a solvent if I need to remove the tile.
Had a brief "thread discussion" with Dekay on this about a week ago and decided to try it as my CD player went out of warranty about a month ago. Go to Home Depot and buy the industrial vinyl floor tiles (3 at about 80 cents apiece). The industrial tile is much heavier and "deader" than the thinner peel and stick but requires an adhesive. Being lazy, I bought 3M outdoor reinforced carpet tape (double-sided) which is black and VERY tacky. Cut pieces and attached them to the underside of the lid of the player and the sides (except where ventilation holes were). The results-a definite improvement in bass performance-bass became more powerful and easier to follow. There was also an increase in transparency with individual instruments becoming clearer and easier to hear-vocals, particularly ends of sentences or verses where the voice "trails off" were much more easily discernable. On the whole, fuller, but also cleaner sound. Definitely worthwhile. $2.50 for the tiles $7.00 for the carpet tape. (Canadian $) My equipment is not ultra-high end so YMMV. Blake
An ENT doctor friend of mine says it is the best tweek. Then again, it is good for business I guess.
I would seriously question the wisdom of possessing nutmeg under the imminent Bush administration but agree fully with its value to those of us who know fresh-grated from packaged-powdered.
I agree Copernicus. Thats the best bang for the buck there is when it comes to inprovements in sound quality.
Some of you thrilled at your 5 dollar tweaks but 2 bucks worth of weed will dramatically improve any system.
Go easy on Khrys. Sense of houmor is refreshing in this obsessive forum surfing......
