Townshend Springs under Speakers

f you haven't tried "springs" regardless of supplier under your speakers your opinion is invalid.

And without some measurements, then even a “valid opinion” may not be a provable fact. It’s still anecdotal at best.

Did you think this was ASR?
Subjective impressions are the mainstay of this forum.
Nonetheless I think that in this case there is measurement available - even live at shows - that demonstrates the isolation offered by the Townshend devices. Whether or not this is preferable is up to the individual. 
I don't see any evidence of the isolation or 'mechanical sink' capabilities of the spiking approach.
Apart from 3rd hand reports from Richard Vandersteen (albeit weighty opinion in relation to use with Vandersteen speakers), it does seem to me that the naysayers are made up of people with no experience of the Townshend products - some with another axe to grind.
Most everyone who has used them or heard them demonstrated has a positive opinion, anecdotal as that may be.

OK… What is ASR?
Do you recommend it?

So what makes his speakers less responsive to springs?

I am not a total naysayer, I just want to know how they work… and whether they would work with my speakers. (Before I spend the money.)
And academically… what makes them work with some speakers and not others seems pretty interesting.
My speakers are currently on a concrete slab, but will be soon moving to another house on a hardwood floor (on joists).
They have been on spikes for 15+ years (on the concrete slab).

I could picture having a slab of granite on springs, and the speakers on spikes on the granite. This assumes that the new floor might be worbling the speaker.

There is no axe.

Audio Science Review. A forum where only measurements are considered and subjective opinion is pretty much ridiculed and shouted down.
Personally I think it is useful for the measurements - some of which I've found to corroborate my subjective opinion of components I've owned and got rid of (years before), but subjective assessment doesn't count on that forum.

Don't know. Given the wide range of speakers that have had positive endorsements, if it doesn't work with Vandersteen speakers they would seem to be an outlier. 
The other question is whether Richard tried the Podiums on a range of his speakers or just one of his top models which had been highly optimised for another approach?

That's wise. I've experimented with other (cheaper) isolation options and found them more effective than spiking for my equipment/room. That, along with people using the Podiums with same brand/type of speaker to excellent effect, gave me sufficient confidence to bite the bullet.
I'd advise to read/research as much as you can and attend a demo if possible (wasn't for me).

@audiopoint, Yes, we are now in the Nashville area and loving it.  Also, The Audiophile’s Wife is seriously considering writing again.  If fact, we are contemplating a shared site where we sell audio cables and she hosts her blog as well as other fun antics. 
I did have some Apprentice platrforms in my rig here for a season.  The speakers I used them under were the Acoustic Zen  Crescendo and my current Dali speakers which I have had for some 4-5 years now.  
Always liked the sound of your products and that Energy Room you built for Andrew is a listening experience I will never forget. Never! Just a sensory delight. Even the sound of my own voice was startling in that room.
