The rack for my basement stereo is cheap and flimsy. I did the sandbag thing on the bottom shelf a while back and noticed a slight improvement in the sound. I found some bubble wrap the other day and read that some people are placing it under their cd player. I tried it and I got a slight improvement in the sound, nothing night and day, but better none the less. The overall clarity improved, a bit, only if I really paid attention and the qucikly removed it. I know I have to build one of those "flexy Racks" one of these days, but in the mean time, what else could I do to improve the sound by tweaking?
Follow Ups:
I tried the bubble wrap against other tweaks (anything from roller bearings to inner tubes, sand and super balls), and it really didn't deliver much at all. I think it's because the bubbles are too tightly filled with air (I used those with a 3/4" size bubble in thin plastic). I got better results under light components once I popped about 2 out of 3 bubbles, forcing a higher weight onto each remaining bubble.Inner tubes are considerably more effective in my experience, but you're gonna have to spend about $2.50 at Walmart to get a small one :)

I think I could try the inner tube idea. Should I get a BMX style tube or a kiddie bike tube?
depends on your component size. for my CD player I got a 12" tube for kid bikes since it's only 11x17 in size. For the big amps i use 16 tubes. BMX seems to be 20" by default, so you need to have a rather large platoform on top of these.Just keep the tube as flat as possible - it may seem like no air at first, but if you compress it with a platform it will still wiggle.

If I went with the 20" tube, would it make sense to sandwitch it between the rack and another piece of wood? I was thinking that I could still keep the bubble wrap under the cd player and stick a piece of wood with an inner tube between it and the self on the rack. I was told that I should try Vibrapods, but this is a 80 Dollar cd player, I would be spending 50 bucks for it, why should I not just buy a new cd player? I though of slicing some tennis balls in half with a bandsaw and sticking those under the feet in conjuntion with the inner tube/ bubble wrap thing.
Hi tuneman,Welcome to the world of the Tweak.
Do it carefully and the result will (effectively) be a new music collection.My suggestions are in the link below. Enjoy.
Happy Listening!

If you are a DIY advocate invest in a small bicycle inner tube slightly inflated or purchase a mylar balloon and slightly inflate it. Place either the balloon or tube under the CD player.The mylar balloon (unlike the inner tube) is not porous and the air or helium will noy leach out of the balloon. The ballon will cost less than $2.00 complete with helium, and the tube will cost around $3.00.

I 'upgraded' from a bubble wrap pillow under my CD player to a bicycle inner tube. The inner tube is much more consistent and stable. The difference in sound is very obvious. Better bass and clean highs (like you added a power conditioner or something).
Touching the inner tube, while the CD player is running, I could feel the vibrations. I also placed some weight on top of the player (philips 963SA).

Bubble wrap will lose its bubbles over a short period of time.Why not try using some Vibrapods as an inexpensive-$24 for a set of four- and long term solution? They work much better than the bubble wrap.
my amps have vibrapods under them - stock, matched to the weight of each unit. Placing those directly on a 2.5" maple stand compared to placing an inner tube, a paving brick as platform and then the amps without vibrapods on the platform, the inner tube clealry outperforms the vibrapods, plus is considerably cheaper.Now, the tube/paving brick (2x18x18 $1.89 at home depot) sure don't look great, but the sound beats the vibrapods in my setup. I tried the combination of all first, and that was a bit muddy in the mids, probably because of the "double spring" effect of inner tube and vibrapods.
Even $2 super balls worked better under my amps than the vibrapods. However, they are better than nothing. Placing the amp on the maple without any device in between was the worst of all versions I tried.
I'm now looking for suitable spoons to finally build roller bearings for the amps (need to be strong for the 120 pounds they'll be asked to balance). On my CD player, an inner tube and roller bearings above that haveshown the best results.

All these dyi tweaks can be had for a few dollars that are well spentcheck on a~gon a guy sells mapleshade isoblocks for $10 a set(4) clean looking, and they work but i still like the vibropods
