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 is very interesting, because at louder volumes my new subs will cause oscillation that's from either mechanical and/or aerial feedback. It's been in the back of my mind, because I don't get it at the volume levels that I play music, but still...
I'm getting upgraded feet for my table, that use an internal spring system, so the results may be promising, as I attempt to eliminate this oscillation.

hi kenny
before you spend any money try out the townsend audio seismic isolation platform, all you need to know is the weight of your piece of equipment , then the platform can be supplied with the correct load cells , the isolation provided is down to 3hz you will get no better for the money if you check my previous link you will see where you can purchase at high discounted prices , 
if you start with your loudspeakers first you will hear first hand what isolation will do when done properly, the seismic podiums are ground breaking products , after all its your loudspeakers that cause nearly all the vibrations when playing music especially if they are spiked to your floor ,
please check out max townshend youtube video showing the positive effects of the seismic podiums and demonstrating the negative effects of  vibrations from using spikes even on concrete
my honest opinion is until you can completely isolate your speakers , your system can nether sound as good as it is , you are basically throwing your money away by keeping on buying better electronics.
isolation has provided the biggest sound improvements to my system , the biggest effect was from isolating my speakers , it was huge mind blowing i just could not believe the difference in sound quality . you can hear every instrument being played , the speakers become so transparent ,and musical  its something one has to experience for ones self ,

I’m having a bit of trouble understanding the benefits of isolation for speakers.

That being said, I do have modular halcyonics type units under my turntable and even with it’s weight at over 150 lbs, the active vibration cancellation when turned on acts to focus and free the sound. And there is already a passive effect below a certain Hz. That can’t be defeated to evaluate its effects.

i also have 3 additional platforms I’m going to install under the BHK monoblock amps and a tube pre amp, so obviously I’m quite a fan of active vibration cancellation.

My TAD CR-1’s have their concentric tweeter/midrange mechanically isolated /suspended from the cabinets to avoid woofer vibration from oscillating those drivers.

But.... I’m failing to understand the benefits of breaking the mechanical ground path for vibration and potentially allowing the cabinet to even minimally move back and forth on a springy suspension.

Is the benefit that less vibration gets into the electronics? If so that seems best dealt with at the electronics.

I do love Soundlabs but I’m wondering if the benefit the OP hears is a result of the stat panels getting less vibration from the woofers. I have only heard full range soundlab models, and not their hybrid designs.

i have not even installed the TAD supplied cones or spikes on my speakers, since the factory stands are quite stable. I read that most TAd owners don’t install the spikes or rounded cones.

my Halcyonic type units could support the weight of the speakers, but I feel they would be constantly oscillating from the forward and back motion of the woofer.

I do have my subwoofers on 20" Sistrum speaker stands, and have heard the benefits of sistrum devices under other turntables and speakers, And i have heard the benefits of mechanical grounding.

I’m planning on using the active vibration attached to 3" maple Timbernation platforms (which is how the turntable is set up) but with sistrum cones between the amp chasis and the maple .

in this configuration the vibration sinks to the maple, which is then isolated from floor born vibration.
