Is it idiotic to stack an amp and tuner directly on top of a CD player?

Thanks. I have owned Salamander equipment before, and it is excellent. But I am attempting to work with a nice vintage wood piece of furniture.

I have a nagging suspicion the significant magnetic field and or the vibration produced by the transformer of the amp would probably have deleterious effects on the performance of the CD player. Not to mention on the amplifier itself. However, the two components could be fairly easily isolated from each other, both magnetic field wise and vibration wise.

Thanks. I think that, as a temporary solution, I will stack the amp on the bottom, then the tuner, with the CD player on top. The tuner won't be on when the CD player is in use, and there will be enough space between the latter and the amp to reasonably disperse the heat.

Don't know about vibration issues, but it should be safe enough until I find a more elegant solution.

I am still wondering, though, if anyone knows of a high-quality single isolation shelf. In other words, a shelf on four legs that would fit over the bottom component, and be strong enough to hold one or two relatively heavy components above. 

Never stack components. Period. What you could do since you want to utilize a particular piece of furniture, is place Herbie Audio Labs "Big Tall Tenderfeet" between each stacked piece. This would give each component in the stack some breathing room and absorb a good bit of vibration between them. I’ve experimented with Many different types of "footers" in my system and Herbie’s tenderfeet have given me the most consistent results. There are two types of Tenderfeet. "Tendersoft" are intended for lighter components, "Extra-firm" for heavier components. You can check them out here: http://herbiesaudiolab.net/compfeet.htm
Steve and Robert Herbelin are great guys to work with. You can email questions to them and get a very fast response.
