Has anyone had experiences good or bad with speaker isolation or isolation in general ?

hi
i have been enjoying buying and listening to hifi for some 35 years now and have seen many items come and go.I have also been interested in the audio cable discussions and i agree that cables do make a difference how much of a difference is a very individual, and a system dependent situation. There has been nothing that has got me so excited and improved the sound of my system that has ever made me want to really share it with fellow audiophiles until i started to try various isolation products.With so much choice from affordable to very expensive i found the hole subject very confusing and i did not know where to start. After trying lots of various products all shapes and sizes with very different results i decided to read reviews which is something i do not usually do to get some advise.I read a review on the Townshend audio seismic podiums they are isolation platforms that go under your speakers .This company is very famous for isolation ideas and have been around some 50 years based here in the UK they also had a factory in the USA back in the 1980s. I contacted Nick at Emporium hifi  and he agreed to install a pair for me so i could have a listen. My speakers are sound-lab dynastats which i use in quite a small room but with the adjustments give a nice sound. After installing the podiums we both sat down with jaws hitting the floor these podium things completely transformed the sound of my system to absolute perfection. After all this time trying various products under my equipment i have now isolated my speakers and the sound quality is exactly what i believe we all are chasing, my sound-labs are now transparent no more bass problems i have just got one big 3D sound stage the dynastats are now very open with deeper much better bass everything is perfect. I now believe isolating your loudspeakers is the first port of call i was so impressed by the Townshend audio seismic products i now sell them as i have never come across anything that has given my system such a great upgrade , the sound is the same as before but now its just so much better its playing deeper bass but tighter much more resolution and no boom , the midrange is so much more human sounding realistic and spacious with the top end so refined and perfect , is anyone using podiums and had the same experiences i would love to hear from you thank you john

This of course means that in order to escape at least some of the seismic type vibration one needs to decouple from the physical surroundings entirely, including walls. Furthermore the effects of seismic type vibration don’t necessarily manifest themselves overtly, e.g., needle jumping from the groove, it can be more subtle and insidious. You don’t know what you got til it’s gone, like the song says.

I wonder if if the recording studios account for seismic activity!?

I'm going to stabilize my rack and isolate my gear.

very true. I knew I had s seismic problem as I can feel the house shake with traffic but installing a solution that gets rid of it completely (at least for my turntable now it is on an active platform) was transformative. Everything is rock solid stable now and all sorts of subtle timing cues that were masked before are now evident. I've also seen the same effect installing roller based feet below my amps, oddly it made the amps sound less loud, presumably the effect of removing noise and harshness that is perceived as unacceptable loudness

hi everyone,

Once you have isolated your loudspeakers from the environment , that i believer is a large chunk of the seismic vibration  problem solved,
You need to stop the energy from your speakers going threw the floor and surrounding services back up into your speakers and from entering your rack/ electronics distorting the audio signal, Since i have isolated my speakers with Townsend Seismic Podiums i am now tweaking my system to levels i never new was possible ,
 if you have invested more into your set up than myself then i feel the benefits will be greater,

I am now looking to treat all the unwanted vibrations in my system, i believe starting from the speaker terminals back threw every connection point to my wall plug socket will also help three up the signal, by reducing all the unwanted vibrations caused by the equipment themselves, Geof is the man to help achieve this goal..

Years ago in the UK, Mana sound frames gained a huge following due to there isolation techniques, back then they used damped glass with upside down spikes at all contact points,
Many Linn LP12 owners would use the Mana Wall shelf to isolate there LP12, as this was suggested by dealers and Mana to be the very best way to isolate the TT,
The way Mana suggested isolating your speakers was a wood type platform with a metal frame all securely connected by spikes , so the speaker base platforms were actually spiked into your wooden suspended floor or carpet / concrete floor..
The main Mana equipment rack was also spiked into the floor with damped glass shelves resting on upside down spikes with a metal frame,
Another product from Mana was the sound base, which was a big wooden type platform sitting on upside down spikes all metal frame with spikes into the floor, the idea was you then placed your shelved rack on top to give an added level of isolation,
Based on the knowledge of seismic vibrations, was Manas use of spikes not effective and did many people then spend money on a floored design, even the advised wall mounted spiked TT shelf does not seem such a good idea from the findings of Max Townshend and Geoff Kait,
to me seismic isolation to be effective you should use a spring type product maybe in correspondence with a ball bearing type product,
I now believe spiking any kind of hifi is a bad thing as they say what goes down must goes up, or what goes up most come down, acoustically isolating the equipment  is the way to go, does anyone have a different opinion please?
I am basing my opinion on the youtube video spikes verses pods and some of the very interesting knowledge of Geoff Kait.
