Vibration


Ever hear of putting front end gear on separate isolation platforms
On the floor instead of a rack?

you mean amp stands?
I used to do it with my Wadia CD player. I imagine you are trying to get your components in between your speakers but you want them low so they don't interfere with imaging. If long as you use a good amp stand you should be OK. It really should be no different than putting the component on the lowest shelf on a rack.
Unless you live near a railroad track? Isolation in audio is way overdone.
Hi what are you trying to accomplish here? Lot's of great racks, amp stands, various footers...all of these things make a impact...some better some worse...
Check through the system pages here on Audiogon, you'll find plenty of systems configured with equipment on individual platforms. You can ask specific questions on those pages. You'll probably get some good, detailed answers from members who are doing it.

Yes

Having separate mechanical ground planes for each piece of equipment makes for a noticeable improvement. Also there is increased lateral rigidity because of the floor proximity to the piece of gear as well as a shorter path for vibration to migrate to ground. All these factors makes the sound stage more clear, mid bass punchier, overall texture of sound is more dense and complex. Tom
Mass-on-spring vibration isolation systems. There's really no substitute.
What vibration or mechanical energy are you trying to isolate with a amp stand? Are they just for tube amps to reduce harmonics?
They do look cool sometimes.
Most of those "stands" are more or less a piece of furniture with nearly no effect at the end of day. Here is a done right solution: Vibraplane

You are trying to isolate vibration and/or mechanical energy.
the best way to improve vibration isolation is to tack circuit components and if the unit is old re-tack output transistors(for example) to the heat sinks. reapplying fresh solder also improves vibration isolation. purchasing stands for electronic equipment should have approximately the same vibration isolation effect as purchasing cable elevators.

So you are trying to isolate the amp. What happens if some vibration reaches the amp? It effects what? The sound?
I know turntables are microphonic, some tube pre/amps also. I have never known a solid state amp that was microphonic.
You have shown me the light before, I just can't wrap my head around this one.
Electrons and atoms as they move generate vibration. You don't want to trap the vibration you want to provide a way for it to leave.Tom
Transistors are affected by vibration, so is the amp's internal wiring, among other things. I have isolated a great many solid state and tube amps, maybe hundreds, including John Curl's JC-1s, the big Jeff Rowland amp, the really big 200 lb Classe amp, CTC Bar-B-Q amp, the BWS mono tube amps with outboard power supplies (600 lb delivered), etc.
So you isolated the amp from itself? How'd you do that? I know how I do that but it ain't isolation because that ain't possible.How's the lateral stability of that spring? Tom
Tom, huh?
Huh is also my response to isolation claims. If you have a band pass of 3hz to 6hz provided by a spring system how do you deal with the other 94% or more of frequency's that are self generated by the electronics and left to remain. How do they get out? What about them there vibrations beating around in their cage with no place to go? How do you deal with all of that? Just wondering. Tom
Tom, that's easy. Damping. Let the vibration isolation system will deal with structureborne vibrations above 3 Hz.
Stock answer Geoff.
How so, Tom? Am I missing something?
You have built a storage capacitor for the vibration to reside longer than is natural. The vibration will regenerate faster than you can impede, muddy and store. There are more effective means. Good luck. Tom
Tom, please share your ideas. If they aren't Top Secret I'd love to hear them.
Tom, you need to discharge the "capacitor." I do not like stored energy any more than you do. As I already intimated "discharging the capacitor" is fairly easy and actually rather trivial compared to advanced vibration isolation techniques - you know, as opposed to tennis balls and inner tubes.
