dlcockrum... My
lead-and-sand-filled rigid-steel Sound Anchors component stand sits on
cones atop my home’s concrete slab foundation and I can easily feel
vibration sympathetic with the sound by placing my hand on the stand. Really? That's simply amazing! Are you talking about just low frequencies here, or do the sympathetic vibrations feel like they span a wider range? |
dlcockrum... deep bass frequencies do generate more perceivable vibration into
the stand, but I think some of the harmonics of string instruments and
drums transmit also.
High volumes are required to feel this. I
have my Thiel CS5i's and dual REL Stadium III subs spiked to
the concrete slab as well, so lots of low bass (and other) frequencies
are being transmitted into the concrete.
I should point out that
here in Texas, we have "trampoline" foundations whereby steel rebar
cables are laid and put under tension within the foundation prior to
pouring the concrete in order to allow the foundation to move with the
soil. Thanks for the info, Dave. I've never heard of a "trampoline foundation," but I guess it has something to do with the soil you have in Texas. While I'm surprised that you can detect the vibration in your turntable stand as you described, I have to admit that I've never actually tested my stand to see if it's similarly vulnerable to such vibration. I'll put that on my hi-fi to-do list. |
What’s unfortunate about this thread is that although some of us might have been able to learn a thing or two here, it’s plagued with insults and derision, as evidenced by the number of posts deleted by the moderators. It surely makes me reluctant to chime in ... even with a simple question. This will likely make me the target of the next insult. <sigh>

I've said before, testing and measuring the benefits of vibration
control in home audio should be easy, and inexpensive. I've yet to see
the loop closed. Agreed! Mind you, I'm rather certain that I've heard the benefits of vibration control in my system and because this is just a hobby to me, I'm satisfied with that. But measuring the results of isolation and correlating that to listening tests shouldn't be that big a deal for manufacturers. The absence of that documentation is what helps fuel the skeptics.

actually shouldn't be the ones making measurements for vibration
control/vibration isolation, it should be some third party independent
agency. Why? Aren't you making measurements as part of your design and manufacturing efforts? If so, why not share the results? If not, are you simply relying on trial and error?
Furthermore, even under ideal conditions, and with competent testers,
because of the obvious variations and vagaries in vibration environments
from town to town and city to city and system to system, the results of
such tests would not necessarily be that helpful.
Yes, perhaps. But without initial measurements to use as a benchmark, we'll never know if there's any truth to your speculation.

cdrc I told my son that Star Sound Technology
platforms are just great big peanut butter and jelly sandwiches and he
gets it. Huh? Who would want to put a gooey, sticky PBJ mess under their audio components? That doesn't make any sense at all.

ethan_winer ... I'll never understand why some people are so willing to
measure the wrong things and come to a wrong conclusion, when it's so
easy to measure the right things and get the right conclusion! Under these two scenarios, it's typically equally easy to be mistaken. That you don't understand that almost certainly means that you're coming to the wrong conclusions at least some of the time - and don't know it. |
ethan_winerNo, the burden of proof is on those making the claim. That's absurd. This is not a scientific forum, it's a hobby forum. No one here owes you anything.
Regardless, your claim is silly, because not all assertions are equal. If I tell you the earth is round, I don't need to prove to you that it's not flat. If you think it's flat, that's purely your problem, not mine.
Several experts that I know have told me that the earth isn't really round, but rather pear-shaped. I didn't insist that they "prove" it. |
ethan_winer's profane and insulting post was thankfully deleted. It shows there's nothing to be gained by engaging with this guy.

ethan_winer1agear, if you like the sound of analog tape and vinyl, then you like the sound of distortion Logical fallacy of the excluded middle, of course. |
ethan_winer... At this point I'm
hanging around this thread only for its humor value, to see how stupid
the comments can get. So far, Ethan, you're doing a great job. ;| |
ethan_winer... Yes, many fabulous recordings
have been made on old school analog equipment. But that equipment has lower
fidelity than even consumer-grade modern digital converters. So again,
the perception that analog recordings are more "lifelike" than digital
is a psychoacoustics effect caused by the addition of distortion. This is an old, tired and transparently silly argument. It's the logical fallacy of causal reasoning.
If distortion were the key to the preference for analog recording, then obviously more distortion would only improve those recordings. But of course, those who've made the best quality analog recordings typically did so while working to keep those distortions to the lowest possible level. You have simply confused cause and effect.
Honest, I don’t care who you believe.
Oh, you care very, very much ... so much so that you've resorted to profanity-laced ad hominem attacks here that have resulted in multiple deleted posts. |
ethan_winerBy cleeds' logic, if a little bit of salt improves a hamburger, then an entire shaker full must be better still. Of course, that's not my logic at all. It's yours. I'm glad you now recognize how silly your argumentation has been here!

BTW Ralph, you don’t have to keep saying stuff like "You don’t seem to
understand." I’m certain there’s much here that you don’t understand,
I don’t feel the need to insult you by using such language. No, you use obscene, vulgar language here to insult - hence your multiple deleted posts. Ralph is doing fine, Whiner, and has contributed much here. |
agear Inexplicable censorship. I had a post about NIH-level research involving CBD and Alzheimers pulled. I find it very disconcerting and lessens my desire to be a patron of this site ... That’s not at all what has happened here. You might want to read Agon’s terms of service. This thread is: " Do equipment stands have an impact on electronics?" It is not: "The risks, benefits, joys and science of marijuana and LSD use." |

"Stove piping" is something we all do, but its partly the byproduct of our intrinsically schizophrenic hobby
... Please speak for yourself. Schizophrenia is a dreadful disease. It is not "intrinsic" to our hobby. |
