Sand bags under a cdp - didn't work well

Well I tried the 12" innertube and the results were much more pleasing to my ears!!! The definition increased but not at the expense of increased harshness. Will now experiment with weight on top of the cdp (ensuring the tube has sufficient air to clear the cdp's feet) and hear if there are any differences. I still like the sound of nothing under the player - it seems warmer, more full and lush. Possibly you could call it "colored" as some say tubes "color" sound. I guess it comes down to what you have been listening to vs a new sound that takes some getting used to. All I know is that the sand or cones did not do it for me and the tube has offered the best return for dollar spent yet. Many tx Megasam for this very inexpensive tweak!

Am considering giving the inner tube tweak a try, but have a question. I have a transport and a tube DAC rather than an integrated CDP. Would you put inner tubes under both the transport and DAC? Mine are currently on BDR cones if that matters. Thanks!

Fpeel: I tried the tube on my Bel Canto (under a piece of MDF) and did not like the change in sound. I should be receiving a couple of sets of the least expensive Mapleshade cones later this week and will give them a try under the DAC. The Bel Canto is very light (like a feather) and I think that this is why it did not work very well, though I did not try weighting it down as I had run out of clearance in my cabinet. If you get a tube just try it on everthing. Like I said before it was the best tweak for my little mini system and really made a substantial improvement in the sound quality. I gues that it just depends on the gear and it's location. I wonder what the tube (under a platform) and cones on top would sound like as you would be isolating the platform, plus draining off the internal vibrations from the gear as well.

Spent an hour and $30 yesterday threading nuts onto 5/8" threaded rod to capture 4 mdf shelves between aluminum fender washers, no neoprene. BIG improvement in soundstage but my favorite female vocals became unlistenable: harsh, edgy, grainy, 1986 $99 cd playerish. Didn't have a bicycle tube handy so I grabbed the thin urethane mat off my workbench that holds small parts in place while I sand them, folded it double and put it under 1995 $200 cd player. Soundstage still excellent, speakers almost disappear and the electronic hash/grain is GONE. Gotta get me one a them tubes.

The mat sounds pretty good too. If you get a chance play them off and post the results.
