All I can say is WOW!!!! I don’t know where to start. Everything seems to have tightened up. More bass control. The midrange is way more forward and present. The spacial separation is insane. You can hear every instrument and nothing overlaps. I can hear the bass guitar and bass kick drum at the same time and can hear them both. The Auva 100 feet would appear to fine tune everything. I have just started to listen to some blues and Jazz. I will get into the classical journey as well. All I can say is this is a very welcome addition to my system. I feel like I am sitting 4 rows back from the stage. 20250528_170555.jpg
 
Agree, i have them under my Altecs as well, and the addition has been pretty transformational

I finally received the Focal Viva stand I ordered to use as a center channel stand for a 3rd Focal Diablo speaker I use as a center channel when my 2-channel preamp is in Home Theater Bypass mode. I now have 5 sets of Auva 70 feet for 3 speakers and 2 subwoofers.

I couldn't tell you how much if any difference they make since they went on with the new speakers. I love the felt bottom that makes it easy to move the speakers for cleaning, unlike the GAIA that sticks to the floor.

I did add four IsoAcoustics Orea Bordeaux Isolators under my Hard Maple Edge Grain Butcher Block my turntable sits on that you can see on the far left of the picture.

Oh man. I don’t know what they designed here, but they do wonders. I started with the DAC, played a few songs and there was a noticeable difference in tonality. Things got crisp the bass was more forward. The next set went under the CDT, and there was a smaller noticeable difference. The biggest Improvement was when I put the last set under the Pre Amp. All of a sudden my gain on the volume changed, I can add more physical volume without any distortion. As you know I am running Sugden Masterclass gear. The total addition of all three, made it sound like a live performance, like I am in the studio with the band.

I was listening to some Doug Macleod blues, and that was a test of these isolators. It is completely dead quiet, you can hear strings plucked on the guitars. The kick drum is solid and forward. I can honestly say every time I add something to this system I get great results.
I tell people, you don’t know what noise on an audio system is, until you don’t hear it anymore.

I bought a Saturn Audio 103C Power conditioner. The noise level went down dramatically. After that, I added a 20 amp dedicated cct just for the stereo. Now my system is completely noise free.

Now I can say you don’t know what vibration does to an audio system until you can’t hear that anymore.

My goto music for testing.

I was so impressed with the first 4 sets for my components, that I ordered the rest this morning. These will cover my Mono blocks, Phono stage and Turntable.
 
I use the Auva 100s with my Daedalus Argos V2 speakers, and agree with the prior comments. I previously used the supplied spikes and Daedalus isolation devices for speakers, the latter to my ears didn't add or detract from the SQ. I also use Stacks EVO component isolators under a couple of pieces and find, in my systems that they are more effective than the IsoAcoutics
 
I'm looking at the Stack Serene LP Stabilizer, to compare to my Origin Live Gravity One LP puck.
Awaiting the version with longer mandrel to accommodate my particular spindle.
Curious to see if the Stack approach works here.

I have the LP stabilizer on order. I should see it next week. I am using the Michell clamp right now.

Interested in your findings. Remember, the Stack stabilizer is less a clamp and more a puck. It doesn't screw down on the spindle or mass load the LP, acts more like a conduit for vibrations contributing to noise, or more accurately smear/distortion.
 
The attention to detail focus is now noticeable. Not sure if I said that correctly. The clarity got crisper, I like it.

Are you referring to the Serene Stabiliser, our the Auva 100 footers?

I've never tried the Auva footers (I use Townshend Seismic Podiums under my TAD speaker stands and am very happy with the results), but employ Auva EQ footers under my power amp and one of my turntables (TW Raven One).

I would highly recommend using the Stack Serene Stabiliser in conjunction with the Serene Mat. They have a special synergy and are my preference to using either the screw-down clamp and bevel that came with my AMG turntable, or a Stillpoints LP1, which I also have.

I'm looking at the Serene Stabilizer. I could try the mat as well, but truly getting excellent results with my Acoustic Revive RTS-30.
I guess I could try both.

I’ve installed some Auva EQ under my pre, DAC and switch with great success however under my heavy tube amps not so much.
I’m curious as to what you mean by ‘empty’ Auva under your amp. Is this as simple as removing the silicone insert or something else?
Appreciate any info.
