Stack Audio Auva Isolator

Ozzy,

My Auva 100 are the best isolation devices I have ever heard to include Stillpoints, Isoacoustics, Audiopoints and Symposium Roller Blocks.

You will hear immediately, tighter image focus, better soundstaging/layering, more ambiance retrieval, disappearing speakers and the bass is tight and impactful...

From my reading, the reviewers liked the AUVAs as they mentioned the Townsend were adding something to the sound and would boil down to preference but they are way more expensive.

I have, but have not yet used, Townshend Seismic speaker podiums. I too have Townshend Isolation Corners on my Sound Anchors rack and pods under subwoofer, amps and componenents. My 150 lb.speakers currently use those spikes that fit into metal discs.

An acquaintance of mine who makes cables for a living and has great ears bought a pair of the Townshend Podiums and he said that the Townshend podiums were the most remarkable thing for his speakers. Like a component upgrade. He was floored. And again, he uses his ears for a living in cable design. 

I messaged Shane(An Aussie Audiophile) about the Stacks and he told me that he used Townshend's and that while they were very, very good, he felt Stacks were better. That the Townshends "smeared imaging slightly", that the baffles slightly moved(which Townshend refutes and says that the correct cells must be used and speakers isolate down to 3hz) and Townshends were more expensive. Although I don't know why cost was even brought up..... But- Shane has suspended wood floors. I have tile on concrete slab so I wonder what effect Shane's wood floors have in the equation. I'd hope someone could do a comparison video of Seismic podiums and pods against Stacks. Max Townshend did a video on the Podiums vs Spikes. Stacks are spikes. Some people like spikes. Some people like rigid springs. Curious on the science. 

 From Max Townshend on Speaker Isolation 

Speakers and components vibrate from sonic waves to each of them and they each vibrate from within.

Spikes are hard coupling to the floor and rack while heavy springs are decoupling.

Science should be able to show the difference between the two. 

@vinylshadow  - Can you clarify for me your point that "Stacks are spikes"?  They only incorporate spikes if you install them into the bass for use with carpet. On hardwood there is no use of them. Thanks

Thanks for the added comments. I appreciate it.

I have owned the Townshend podiums with my Focal speakers, and I thought they were very good. Better in fact than Iso-Acoustics Gaia 1’s.

But I sold the Focal’s and moved on to the Clarisys. They are the Planar type that weigh about 230lb. The base dimension is about 30" x 15". The Townshend size available will not fit, and I would be concerned about the weight and the possibility of them tipping. So, at present I have Iso-Acoustic Titans underneath them.

So, to me, the Stack Audio seems like it would work well. If it is as good or better than the Townshend’s I would be very pleased.

Should I use the Auva 100 spikes with them or not? I have a thin carpet (no padding) over a concrete floor.
