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

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.

hi
when i was experimenting with stillpoints the dealer said it was best to start with your loudspeakers as they cause most of the vibration when playing music, which can travel to your delicate electronics , it made sense as i like to play quite load so i get the sense of a real life like musical experience .
i didn't get on with the stillpoints and was advised to try the Townsend seismic podiums which were a very new product he recommended checking out the you tube video with Max townshend demonstrating the effects of seismic speaker isolation .
All i can say is they transformed my system from great to absolutely amazing in every area , my speakers have completely disappeared every area of musical reproduction has been improved to incredible levels ,
PMC loudspeakers are a solid box type speaker used in recording studios around the world , the company is planning on building a podium platform into the design of there loudspeakers , i have not heard first hand a PMC loudspeaker on a seismic podium but hearing there plans the effect must of been similar to what i experienced , 
like all hifi you got to try before you buy all i can advise is im so glad i tried as they transformed my system , over the years i have owned some outrageous hifi , i am the only audiophile in the UK to own the Nola Grand Reference being driven by 4 of the Edge NL reference mono blocks the front end was a DCS stack which i swapped for the Esoteric PO1 with a pair of D01s and the Esoteric clock .
That was all some years ago when business was very good , all i can say is im enjoying my lector cd707 with psu7 my little Nordacoustic class D amps driving my soundlabs with Townshend audio seismic isolation and a couple of mpingo discs just as much ,
i didnt get into isolation back in the day all the money went on equipment , i still say putting my sound labs on the podiums has been the biggest upgrade i have ever heard in any of my hifi systems , i believe there is no harm in you trying good luck , check out the video on youtube explaining the effects of the podiums i found it very interesting and extremely beneficial to my system as they have made a huge improvement.

Thank you for the Townsend recommendation, and I have briefly looked at the isolation products for speakers/subs.
I started a post about stabalizing my rack, because I have it sitting out from my front wall on a bouncy floor. My rack is currently spiked to the wood floor, so I'm considering adding footers under the spikes (Mapleshade Heavy Feet). For example, Herbie has a heavy version of their pucks for this. Once, I pick a solution, so that my rack is at its new height, I will secure the rack to the front wall, so that it is rigid.
I will start with my rack, and then work on the rest. My table is getting an upgrade with the new feet I had mentioned and a better bearing.
