Isolation Devices, Something to put on top of unit

Hello, I need to find a good device(s) /or/ method to kill the airborne vibrations that attack the top of my cd player and preamp... Basically the shelfs under the components are completly dead, you can not feel anthing coming thru the rack or the bottom of the units, its just the top plate of the unit, which is the largest and weakest surface area anyway... but again the rack is excellent, it has 3" thick maple shelfs and with full bass in the room does not show a hint of vibration. Don't get me wrong the system sounds excellent and never skips or does anything funny because of the top plates dancing to the music, but of course I would like to eliminate this.
-Should I just get some 2" solid maple blocks that fit on each unit and do it this way as this is how the shelfs are, with like a sheet of fabric inbetween or something?
-I would like to keep this situation as CHEAP as possible, again I would like the benifits but really the system performs flawlessly.

--I have a turntable in the system too, it never skiped once at full output so its good, the plater does not vibrate, just the dustcover(so I just leave it open

--Wadia CD player never has a problem but would like to put something on top. It does not get hot.

--Mcintosh Pre-amp like to put something on top, it does not get hot.

Thanks fellow audio people

Hmm, yeah Virtual mode looks good, I need power conditioning as well so maybe I can kill two birds with one stone. thanks

Right, I won't cover the holes, there are a few but on the very back of the preamp only, I have tried the dynamat, it helps, but for the wadia cd player you can not get inside that area without the correct tools and taking the whole thing apart, besides I believe that it does have some from the factory already installed, suggestions are interesting, I definatly will try, now I need to find somebody with cigar boxes :)

I can't find HRS?? They are not in the manufacture list on audiogon and a quick google only gave me some CES type show talking about somebody strategically using them. Anybody got links? or priceing? Thanks

Alright some good ideas here, but unfortunatly moving the rack is near impossible, not only due to the position in the room, but the cable problems that would occur. again it has never skipped or anything in this position, although I am sure putting the rack in another room all together would be the greatest improvement, but back to the real world, gonna have to suck it up and throw something on top :)

Interesting, I just don't have real options in placement, but I will first try a cheap bag of sand over the transport to see what happens, before investing in anything, just to know the effect, my system is fairly sensitive no doubt to changes, its really not like a stereo anymore its like a tuned instrument, in a way this is good, but in other ways obviously has problems of its own, again I guess you get to a certain level of quality and things become much more clear as to what will work and what will not.

Actually I have giant solid maple cutting boards under the components, and it works perfect, if you see my original question at the top of the thread, 3" thick.... Thats what I originally asked to be honest if I should just go that route, but its still not super cheap for a good cutting board made out of anything, so its almost just as well to drop 50 bucks on an actual isolation device at that point. I guess we will see, I think a 2 dollar bag of sand is my first approch just so I can adjust the weight and see what its gonna do all together.

Tbg, what do you use? I'm not sure it is a bandaid, but unless someone builds a player with a 20 pound granite or wood lid in the first place, what is the fix for this accept moving the entire system into another isolated room from the one you are listening in? I would have to believe that even the Meitner or Reimyo or any of these extreme cost players are not gonna just sit on a shelf and create no vibration thru the top when you touch it.

Sounds good guys, I'll take a look, yeah you can only do so much I know that, just want to do something rather than nothing you know what I mean? Thanks

I have a couple marble tiles, that I put back to back weight around 10 lbs, they seem to do something decent, I have some isolation pucks that I set them on, but can still feel the top vibrate a little, so should I dump the pucks and go with a fabric or something to just lay them flush on the top of the player? thanks

very interesting, problem is the Wadia is like a damn lockbox, can't get it open without some special tools, it uses a very off size like 2.5 mm Torx bit, which yes I can remove a few, but can't get the rest as it has some type of internal latches... also it does not have "Top" plate it is all one box that slides off the unit in one piece, so it is not seperate where you can just take of the plate, virtually they entire unit would need to come apart... I am not sure but I believe they did this to Deter anyone from trying to easily copy the digimaster system housed inside.
