Townsend springy platforms for my Sasha 2s, springs not ISOA GIAS, HRTs for electronics???

That is a good plan. Rest assured you can blame me either way. Also you can blame me even for stuff I never came anywhere near! Robert Downey Jr warned me, goes with the territory. So long as you provide your own paint pen I am fine with autographs. Just please no cameras, the Millerazzi are beginning to annoy the neighbors.

I wouldn’t bother with spikes. But if it will bug you not to try them then by all means go for it.

My Moabs are almost as massive. Here’s how I turned it into a relatively easy one man job.

First, measure three corners of each speaker where they stand right now. Cut a piece of paper to match their footprint. Place the paper on the Podium centered L to R and back to where you think you will want it, with a lot more base sticking out in front than in back. Tape the paper to the Podium.

"Walk" the speaker off to one side. Put the Podium where you want the speaker to go. Measure to the corners of the paper to be sure it is exactly where you want it. Now all you have to do is walk the speaker onto the Podium.

Tilt and walk it close as you can get it. Watch the towers! When you’ve gone as far as you can this way, lean it onto the Podium, go around to the other side, and walk it the rest of the way into position. No heavy lifting, it is all a matter of balance and leverage.

If you want to do spikes, do spikes. Then use the same technique to remove them. Tilt the speaker to one side. Place a piece of wood under the raised side, remove the spikes on that side. Tilt and remove the wood, lower the speaker. Repeat on the other side. Leave the paper there to protect the finish on the speaker. Easy peasy.

Right. That's what did it for me. For a long time the prevailing wisdom has been to pretend that cones and spikes act like diodes that pass vibrations one way only. This never made much sense but it did seem to work. 

Then Max came along and showed that not only do the vibrations go both ways, they come right back up through the floor into the speaker and cause the speaker to vibrate enough to smear transients and blur imaging and other fine detail.  

It would seem that by allowing the speaker to move freely there will be a loss of dynamics. Because f=ma. But the mass of the speaker cabinet is so much greater than the moving mass of the cones this is negligible. What is not negligible is the ringing that is eliminated with springs. This is clearly demonstrated with the iPad seismograph. 

What is harder to demonstrate, but easy to hear, is the improvement in detail and dynamics. Because dynamics are not just the absolute volume we hear, it is also the dynamic range from the quietest to the loudest that we hear. So while Podiums probably do take some tiny smidgen of volume off the top, they lower the noise floor so much that it creates the feeling of more dynamics not less.  

This at any rate seems to be what I hear and noticed right away when using them. I know why I noticed too. It was because I was expecting less dynamics not more, and was surprised when it felt like more not less. Then I realized the reason: the ringing was gone! 

Interesting question. They work great on my wood floor, a lot better than anything else I've tried. And there are guys with concrete and tile and hardwood etc. This is one of the demos that put me over the edge, Max stamps his foot from 15 feet away, you can see the spike speaker ringing while the Podium speaker is dead silent. https://www.youtube.com/watch?v=BOPXJDdwtk4  That is one of those convention center solid concrete slab floors. Concrete transmits vibrations just fine. I knew this from growing up living in a basement, but still it is cool to see. 

In spite of being isolating springs and all it does still seem to matter what they are placed on. Another guy on carpet said he tried a slab (wood or granite, I forget) under his and it improved detail even more. So I tried BDR Round Things under mine and sure enough, it was good before but even better with! No surprise I guess. None of this stuff is magic. It all works together. However good something is, it can always be tweaked and made just that little bit better.

Robber feet. Good one. 

Townshend will put a spring in your step. Heh.

Yes they sure can. That was me last year. I was totally sold on cones and rigid vibration control. Springs were a hard sell but see my threads, the advantages were immediately obvious.

Ordinary springs like Nobsound are so good for the money, and I am a value-oriented audiophile, and Townshend are not cheap. But as good as springs are they do introduce color or resonance, even after careful tuning. The problem being ordinary springs are not damped. I went back and forth a while with John Hannant until it became clear Townshend was the answer to my "problems" if you can call better than just about anything else a "problem"!

You can see my recent system photos now https://systems.audiogon.com/systems/8367 there are Pods under the turntable, phono stage, and amp. There are for now still ordinary springs under the subs. The Moabs are on Podiums.

These were done one at a time. Turntable first, completely eliminated all hint of resonance with a huge improvement in revealing the correct timbre of instruments and vocals. Everything just sounds a whole lot more like what it would in real life. Noise floor dropped too. Blacker backgrounds. Slightly deeper bass with greater physical slam.

I was doubtful Pods would make much difference under the tube amp and was surprised when they made an even bigger improvement than under the turntable! The phono stage was similar but sort of in between. So I can’t really say if there is a logical order to do them in, they just work everywhere.

Podiums are the most expensive so were saved for last. Was going to build a better platform for my DIY springs. But after hearing how much better Pods were, well why go to all that trouble for something not nearly as good? Smart move, the Podiums were the biggest improvement of all!

Well they should be for the money. Not cheap. But you do get what you pay for. Search around, there was someone recently who upgraded from Iso-Acoustics Gaia to Townshend and said it was well worth it they are much better. But I am afraid he may have posted that on the thread Ozzy started, which is a shame as Ozzy decided to delete that whole thread along with all the great information people had contributed to it. Oh well. My review thread is here https://forum.audiogon.com/discussions/townshend-audio-podiums-the-full-review

The key as I put in my review, Max Townshend figured out a way to use just the right amount of damping to control the resonances that plague ordinary springs. Very clever design.

For sure you want Podiums under your speakers. Whether you use Pods or Podiums under the other components will depend on all kinds of things like the component, space and budget limitations, that kind of thing. If John Hannant or one of the others at Townshend is on it you are in good hands, everything he has said has checked out with me, big time.
