Heavens to Mergatroid! Was there was a high level troll meeting and I wasn’t invited? What’s up with that?
Do equipment stands have an impact on electronics?
Mechanical grounding or isolation from vibration has been a hot topic as of late. Many know from experience that footers, stands and other vibration technologies impact things that vibrate a lot like speakers, subs or even listening rooms (my recent experience with an "Energy room"). The question is does it have merit when it comes to electronics and if so why? Are there plausible explanations for their effect on electronics or suggested measurement paradigms to document such an effect?

Seismic simply means very, very low frequencies, like 5Hz down. And it is no boogey man, they are quite real. Ask anyone who has put the Townshend Audio Seismic products (or perhaps Geoff’s springs) under his speakers, turntable, CD player, or tube electronics if they are effective at providing isolation from floor-borne vibrations (which transmit up into a speaker cabinet or an equipment rack, and through a turntable’s suspension, none of which provide isolation at seismic frequencies. That is why the microscope isolation tables selling for $2000-3000 sell as well as they do to those of sufficient means). There are a few here on Audiogon, one in Portland who has invited me over to hear them under his speakers for myself. I already own the older Seismic Platforms (used in conjunction with roller bearings, effective down to around 3Hz), and will be adding Pods shortly. Again, Max Townshend has an excellent video on You Tube in which he explains and demonstrates his Seismic products. It is definitely worth a half hour of one’s time to watch. |
Class, come to order! As much as I dislike being contradictory seismic noise actually encompasses all of the various types of very low frequency, low frequency and higher frequency vibration that can be transmitted via the floor or any other building structure. Thus, seismic noise producers include - but are not lmited to - earth crust motion, other earth vibration, wind, footfall, traffic, subway, ocean wave action, local construction, large fans and speaker feedback. Thus, seismic frequencies should be considered to be primarily in the range 0 Hz to 30 Hz but extending also to higher frequencies. Which is why the Townshend isolation data showed 88% and 97% or whatever isolation effectiveness at 20 Hz and higher frequencies like 150 Hz. Hel-loo! |
I am not a troll,I am a musician and audiophile among many things . There obviously are solutions at various levels or designs to vibration . At 2-3 k per stand under spkr, amp ,pre,tt and digital that is quite expensive to the average joe . I believe this is system related , i have been reading and occasionally commenting since the first comment . I get discouraged by the chastising and belittling of members because they are not smart enough ..there will be different viewpoints , i see this all the time with instruments , there is science yes but there is also sound .. I am well aware of your one unit system gk , not everyone wants a headphone only or a modded walkman . Even if it is the cats meow , which has been debated over and over .. I would be shocked if over half of this thread didn’t say the exact same thing 50 times. Opinions aren’t changing , I said i like Roberts audiopoint they work for me at a somewhat reasonable price considering what they do for my sound.I hated sorbethene it was a no go for my setup . As for your tweeks gk how can anyone even try them when you blacklist any member here to try your "springs" ? Just because a c.a.d machine carves a guitar body does not make it sound better then a handmade martin to me . I respond to final sound, at the price I determine to be acceptable for my situation.

What you see is what you get..https://www.youtube.com/watch?v=K5hBXr3aJus Observational facts: New York City - a real test and listening environment for seismic activity. “Earth crust motion, other earth vibration, wind, footfall, traffic, subway, ocean wave action, local construction, large fans and speaker feedback” Speaker feedback? (Only if you are a poor sound engineer :) Add to that El trains (but not so much in Manhattan), subterranean city and workers 24-7, rivers, shipping and large engines, cab drivers complaining, aircraft, crowds of humanity singing and dancing, plates, glasses and bottles clattering, live band instruments (acoustic and electronic) and percussion and any other type of noise you can imagine… And the liquid in the glass remains stable, not only stable but there are no discernable opposite reactions of the waves hitting the glass; would not they come back then forth again creating even greater instability of the fluid surface? Still extremely calm with a powerhouse subwoofer system beneath and a 1500 watt satellite system direct coupled to the subwoofer cabinet then add to that another pair of identical cabinets located on stage left and a half dozen floor monitors too! Now that is what I call a full frequency range testing environment. Clearly more energy heading to ground (flooring) versus coming up the chain. Tom. Star Sound. |
