Stacking components?


I have a Sony 7700 and am getting a Jolida 1501. Is it OK to stack the Jolida on top of the Sony? Both will be going in a heavy wire 18"x18"x74" tower/shelve unit. The tower will have good contact with the floor and I was going to put a slab of granite, wood, etc. underneath the Sony as well. Also, I was going to use something like Vibrapods underneath both the Sony and Jolida to help with vibration even more. I've heard/read that a small bag of sand or other weight on top of the CDP will help some. Can I combine this effect by having the Jolida on top of the Sony or will heat be an issue? Any other ideas for cost effective isolation in this type of setup? I realize the wire tower isn't perfect for this but it fits where I want it in my den perfectly and it is well made and solid. Here's a link to it(bottom/middle of the page):

I'll also have a small 5 gallon mini/nano reef on the bottom shelf and a 14" Toshiba television above the components. I'd like to try and get it to work well with the components in there if I can.

Thanks for any input.

Elizabeth and Suits_me,

Thanks for your input. That IKEA stuff looks like it could be a good alternative. I wish I had a local store to see some of it in person. I'm only dealing with two components here so I'm trying to make the most efficient use of space in my den by keeping everything in one rack. Since I haven't got my amp yet, I'm not sure about how much heat I'm dealing with. I think I'm still going to give each component it's own shelf and Vibrapods/etc.. I'm more concerned about vibrations with my CDP than my amp. In my setup, with the modifications that I am suggesting, shouldn't that be enough for the amp? Will it really make that much of a difference sound wise in my modest midfi setup? Should I just opt to put the components on my desk beside my monitor? My desk is more of a table(60"Wx24"D), my monitor is about 22" wide and my speakers will be on stands beside both sides of the desk. Maybe by coupling my desk via spikes, etc. to the floor and stacking my components on there with some Vibrapods will be a better alternative?

Thanks again for all of the input.
I have good rack and have seperated AMP and power conditioner. Have wo shevles for assorded CD/DVD/DVDO-HD/Pre-pro/DTV.

With good shelve litle heate issues, I am concerned with elictric effects and such. IDEA and OK and avoid.

Thanks
