As @Patu described above, the Auva’s will likely have less vs spikes, though they had significantly more bass weight/slam vs my previous Gaia’s. They do need time to settle though & one day might not have been enough. Because of the particles, they physically need time to settle & initially they will be lighter in the bass vs when they have settled properly.
Before installing they recommend giving them a shake from side to side on a flat surface to help settle/reset them after shipping but will take some time with music playing to properly settle & sound as they should.
I don’t know how that’s possible, the particles will always be moving and getting unsettled, the more bass content and playing volume the worst and less consistent. There is really no settle with AUVA technology. I’ve never heard any difference with AUVA EQs or AUVA Feet for LP12 after moving them around, I don’t see how it would be any different with regular AUVAs.
I have the Gaia II on my ATC 40A they sound fine, they sound even better because they were FREE!
I traded in a bunch of cables I wasn’t using. They also don’t wobble much. It’s simply something I don’t care about.
I have oak parquette on concrete. Floor construction makes a huge difference. Isolation is recommended for floating constructions and the more heavy and solid the floor is, the better coupling will work.
I’d say its possible as it happens all the time when you compact something. If you vibrate the particles, they begin to settle & compact. The more you vibrate/the more they compact (to a point). The particles only get unsettled if they get removed/shaken, etc.
The vibration will need to be consistent for that to occur, and with recorded music it never is. It’ll be interesting to see what happens if you disturb the AUVAs by leaning the speakers to the sides or rear, if your theory is correct you should hear them going lighter in the bass for a day or two.
Different strokes for different folks
my own experience is the Auva under my speakers was nothing short of amazing.
Even the mrs couldn’t drag herself away this evening and i was playing The Healer by JLH
Why would the vibrations need to be consistent? Once the particles have settled, they stay that way unless they are significantly disturbed. My experience is if you remove them & give them a shake they do need time to settle again.
Different systems, different ears I guess, I’ve never heard any difference with my AUVA products after moving them around. Same goes for the Serene Stabilizer, which gets significantly disturbed with every record you play, although I always shake it just in case.
Good elaboration. Looking at the Herbie gliders, it looks like they act like a pad for spikes to sit on. May I ask if there is a difference between spikes vs spikes + Herbie gliders? In my experience, the bass slam and low-end dynamics are usually ‘amplified’ through spikes thus causing resonance, and Isoacoustics Gaias reduced this resonance (in my system) which made the bass sound more textured, detailed and natural. I do not have experience with the Stack Audio Auvas.
Just curious, will the Auva 70 work better than the 50 for heavier speakers like the Tannoy Legacy Eaton you are using?
Not sure how the Gliders work but they worked better than the standard spike plates under the stands. You can read many reviews about them both on their www and on other places. The 50s were recommended to me by SA as the sweet spot.
I’ve had Iso feet before and they do similar things. They make the bass more slim, some call it tighter which to me is same same. Many fighting room nodes install these with great success and with my former Tannoy speakers the Iso did just that and I hear the same thing going on with Auva. So that’s what these feet do. If this is something that takes your presentation in the right or wrong path is up to you to decide These kind of feet do things but so do cables and some give you more slim bass and some more heavy powerful bass. So IMO they as many things are tuning tools that can help out, or if they take it in the wrong direction they will mess things up.
As said it was a short 1 day test and I will test them more so it was a first impression. Might change my mind later on but being back to Herbie Gliders the presentation in my system sounds more balanced and coherent with more groove and drive again.
There’s no right and wrong with these things, there are so many variables in play.
I recommend experimenting with different material spike shoes also. The heavier and denser the spikeshoe is, the tighter and clearer the sound gets. Granite slabs under the speakers work nicely also. I had spikes + spikeshoes + granite slabs before Auva’s. I’d probably still have the granite slabs under the Auva’s, but I’m afraid my kid would knock the speakers down since Auva’s have felt underneath and they easily slide on top of polished granite.
Yes I’m not at all saying it is a bad product so we are clear on this I guess we always have to fight compromises taking place
I will also assume they perform different using the spikes under them compared to the felt mat which I currently use. There is some swing in the stand with Auva for me and with Herbies they are rock solid. I’ve experimented a lot with soft vs hard pads between speakers and stands and seem to prefer harder feet which keep the leading edge and dynamics better than soft feet which sound bit more lush and blurry.
Many speaker manufacturers bond the speakers to the stand with screws to make them one unit. I also believe Linn Kan required spikes going into the bottom of the speaker for best dynamic, PRAT presentation. Nothing else than the speaker membrane shall move.
These kind of feet do things but so do cables and some give you more slim bass and some more heavy powerful bass. So IMO they as many things are tuning tools that can help out, or if they take it in the wrong direction they will mess things up.
