Put something heavy and that will pour like sand in a zip lock bag. Then put that into a second bag in case you get a leak. Can't get much cheaper than that.

I've used sand filled zip lock bags on top of my speakers with success. Also, just go to a gun shot and pick up a bag of lead. Another cheap tweak that will replace the feet on your player is to get the HVAC rubber/cork blocks. These are the same as what Mapleshade sells only for a lot lot less if you can find an HVAC dealer or supplier that has them.
An alternative is to try placing multiple smaller items on top of your Music Hall like lead shot filled Gumby action figures. If you pick something too heavy like that gi-mungous Golden Gate Bridge bolt Marco [Jax2] use to use it might over dampen the chassis and cause the sound to deaden. Using multiple smaller items allows you some adjustability. Just one Pokey might sound better than two Blockheads, or a Groov-Bee. Experiment!
I have used the Virmode.com "Virtual Mode De Bag!" successfully, and it only recently has been de-throned by the "Mini" Brilliant Pebbles from machinadynamica.com.
Both companies are quite independent-minded, and worth checking out for anyone who enjoys the joy of discovering a "tweak" that makes things sound better, not just different.
To get the full flavor of Virtual Mode's emphasis on being the most cost-effective source one must telephone for their full catalog.
Machina Dynamica is more into tweaks that border on the supernatural, and prices range from the most cost effective, up to the very most effective, regardless of price.
Don't forget the supporting structure/devices for your CDP box, which are available from Virtual Mode, Machina Dynamica, and many other sources, in a multitude of sizes, shapes, materials, and prices.
My little known "find" of a support product is Mi-Roller from Musical Industry at mihorn.com, which is one of the many competitors to the Aurios MIB (media isolation bearing), at a lower price point.
The choices are too numerous in the affordable price range to pick a single champion, but most seem to enhance the listening experience in one or more ways.
I dampend my Arcam9 on the inside cover with a product called" BrownBread", this has dampening sticky side for attachment and aluminum on the other for heat absortion. it is a British prouduct and can be ordered from any dealer that sells any english produck like rega for instance, it cost me $26.00 Canadian, the 3M product sounds to me to be in the same vein.Good Luck Ernest.
I'd try a side of beef wrapped in butcher's paper. Fleshes out all the inner detail you can handle. In a month's time you'll have a kinetic audio sculpture, and the movement of the maggots will act to stabilize those nasty vibrations even further still. The magic "indicator-bone" lets you know it's time to replace it with another. If you can't spring for a good side of beef then my second choice would be some rolled up sod from the garden-supply store. I don't recommend pulling another bolt off the Golden Gate Bridge as my green buddy, The Gumbilator, suggests. I got mine pre Patriot-Act. You get caught wrenchin' out one of those puppies these days and your family will be relocated to Downtown, Buttfukt while they erase all their memories of you with a Dremel Tool. Believe me, premature ejaculation, hair loss and your consumer credit rating will cease to be your primary concerns, Keemosabee! Now if you're talking Brooklyn Bridge, well now, I can part with a little piece of that given the right price!
You don't mention whether the cdp is isolated. Ultimately, that will provide a greater improvement than beanbags, linoleum tile or pucks on top. There are plenty of threads on Agon dealing with the various platforms, blocks, cones or other devices that will decouple your cdp from your stand. Once you've isolated the player you can move on to the next level of tweaking.
Jax2 what do you recommend as acoustic room
I use small children and house pets. If you live in a 'family-oriented'
neighborhood like me, they can frequently be found wandering the streets,
and/or on their way to or from school. I've been encouraged by fellow
audiophiles who've listened in my room to start selling my line of manacles
and gags for just that purpose. Ought'a put that Rives fellow right outta'
business if I ever do. Well, I guess you can still use their PARC device to
position the little rugrats! It's kind of expensive keeping the whole system
fed and maintained, but let me tell you, once you hear it you'll never want to
go back to 'pedestrian' room treatments. You need to get'em between 8-10
years old for optimum performance. Once they get older you just dump here
on the Gon' to some unsuspecting geek who doesn't know better. Oh, and
don't forget to cut air holes in those shipping boxes, and throw in a couple of
Twinkies if it's going to be more than a couple of days in transit. If you
have a bigger room the fat ones will serve you better, but are more expensive
to feed and keep. Cats hung up in the corners of the room make great bass-
busters, but make sure to take em down to use the litterbox on a regular
basis or you'll be sorry. Oh, and be patient on this stuff if you decide to try it
out; the break-in period is a killer! I'd recommend going on vacation and
leave the feeding and maintenance to a good friend or neighbor who won't
report you to the local authorities. Regardless, give it a good month before
you settle in and enjoy the new room!
PS I was born and raised in Brooklyn Heights. Be afraid. Be very afraid.
Marco is right, the effectiveness of snack foods can't be underestimated when applied to audio component isolation and vibration control. I thread my interconnects through Hostess DogNutz® and place them wherever my cables might contact a wall or a power cable. Very effective at preventing unwanted vibration from entering my system and sweetens the sound too.
Marco fails to mention that the reason his Pet Isolator is so effective is because he's implemented the über high end Diesel upgrade.
Clio09: Have you ever read Pierre Sprey's sales spiel for "his" Mapleshade Iso-Blocks? He states that he "designed" the Iso-Blocks, which are nothing more than Wagner 2" and 4" mounting blocks, used by heating/colling (HVAC) contractors underneath furnaces.
But Pierre designed and developed them ... yeah right!
