Well done in persevering Chris, we are lucky, our 150? year old floors do seem level. Pleased you have found them as effective as everyone else who seems to have tried them, we're still still waiting for our inserts to arrive so the speakers are resting directly on top of the Auva's. Did you use a set of the slightly larger spikes on the rear positioned 100's?

Did you use a set of the slightly larger spikes on the rear positioned 100's? Hi Dave, yes the older the house I've lived in, the better the structure seems to have been. Walls, floors, stairs all seem far better than any 'rush to finish' modern cr**. I ended up using the longer spikes on all the Auva's as the shorter ones left the puck in slight contact with the carpet so I couldn't be 100% sure that they were making it all the way through to the screed underneath. Interesting idea though. I'd say I'm more likely to 'tilt' the top cabs from their base (on top of the bass cabs). I'd want to keep the bass cabs as absolutely perfectly flat as possible. There should be some more toys along soon (from Stack!) which may bring some more light to this subject!

Testing the Vaders at the next level of isolation and vibration damping. I already have Stack Audio AUVA 100s under the cabinets and shall be testing the AUVA 70s between the cabinets. Adding the 100s under the speakers provided a very large uplift is SQ, however, I am mindful that the midrange and HF enclosure is still in direct contact with the 12" bass driver enclosure. Surely, this isn't optimal? I have now added the 70s and there is, once again, a marked improvement in SQ. More to come on this. The large shadow gap looks a bit clunky at the moment, so I spent yesterday taking a router to Vader's enclosures. I made a jig and added recesses to top of the bass enclosure and the underside of the Mid/HF enclosure. I must admit this was a rather stressful endeavour! Thankfully, it all went to plan. I realise some will find these claims of massive SQ gains quite far fetched. It is blatantly obvious when you hear for oneself. However, I soon plan to undertake measurements with and without the AUVAs. I have already dialed the 12" bass driver back by 5db. This is a large reduction in output, so there must be measureable differences.

Right just to say that a set of the Suva 50,s have arrived at Casa McBride thanks to Stack Audio and Jason for sorting this out . I am expecting some 100,s later so I have time to try these and see what the difference is . I will state from the outset that I will not be drilling my stands for this listening test , instead the wooden spikes will sit in the thread hole on the feet . Yes I am aware that firm strong coupling will be better but that can be done if like the rest I succumb to buying a set . No chance to do anything today so will it till tomorrow when I have more time . As a pre amble my system is sounding very fine at this point the best I have heard it with both the NVA monos and the Coherent upgraded LB Clock being big pluses . Not sure where things can go from this level but will get back with some findings on the first set either Sunday or Monday .

Quite a few people have placed the AUVAs under the spikes of stands. They got good results with the spikes resting in the female thread recesses.

Finally! Managed to fix the AUVA 50s to my Tannoys. As context, I was always going to replace what I had , some recycled mahogany chair legs with no damping direct on a wooden floor. I had 3 on each cab so I didn't have to worry about equal lengths. That was fine as far as it went, but I hadn't had much free time to experiment with isolation, etc. Anyway, I saw some Hudson bigfoot things on Ebay for 15 quid, so I thought I'd splash out 🤣 on them and see what difference they made. Certainly a massive uplift in bass response but at the expense of some clarity and was a bit too much. But given the price, I thought I'd leave them on. However, I had to balance the cabs on them, meaning they were a bit unsteady, and moving them was a pain. When I read the review of the AUVAs on here they seemed exactly what was needed, so I pulled the trigger on the 50s. Initially I just balanced the cabs directly on them while I worked out how a more permanent arrangement might work. The difference in sound was pretty obvious, the bass response was far more controlled and less boomy that withe Hudsons and everything else was more focused and sounded more "responsive" overall , if that makes sense. I knew from the off I would keep them and needed to sort the fixing. Bolting direct to the cabs wouldn't work as it would lower the overall height and I actually wanted them slightly more elevated if anything. So I added an extra chair leg and made new legs but a bit longer than before , drilling holes for the M8 nuts in them. Now they have 4 legs and are more stable , with AUVAs I can adjust the height to level off aswell. Sounds great, and if anything slightly louder as the drivers are moving more air I think. But , bass tighter with more timbral dpeth and I have noticed more nuance in some tracks, with guitar string tone and parts with more clarity than before. In summary, I am very happy with them and it was £400 well spent in my book. I think the 50s size complements the look of the cabinets overall too. I would highly recommend a try out which is risk-free, really give the return policy.

Great solution for fixing them electronumpty - they are nicely in proportion and look great! Glad the sound is improved too.

Sorry to say not a good day for me my leg and consequent pain were bad today and that was before I became fully depressed after watching Liverpool lose to Forest so just not able to get on the floor and do what is needed . Red Wine and some malt will be the prescription for tonight may feel better tomorrow.

Strange expression, but still sometimes we get blasé about spends. Fantastic that they have produced what you needed though.

Yeah, there's definitely something about these Auva isnt there.
They look great on your speakers too.

AUVA 100, my experiences I have a squarish room, 3.6m by 3.4 with a large bay window behind the speakers. Walls are solid block, floor is suspended pine boards on 100mm joists with 100mm of solid thermal insulation. On top of this I have underlay and berber style carpet. My speakers are Revelator 851, a Troels Gravsend design. These were crafted by Jason, Arke Audio. I have always used Townshend Seismic Bars until trying the AUVAs When first using the AUVAs 100s I placed them under the speakers with no spikes, the speakers rested on them. The sound, while different than that with TBs it was not that impressive. The taught, extensive lower frequencies, that the bars brought was not there. Searching for tracks with a strong kick drum had me wondering what all the fuss was about; the AUVAs did not extended LF here. What I was hearing, or not hearing, was a complete absence of the drum! In its place was a LF mush. Not giving up I attached the AUVA correctly, drilling and adding threads so that I could screw them in to the speakers. An easy job as others have described. Moving the speakers into position is easy without the spikes fitted. When they are in place spikes are easily screwed in. In place what a transformation; taught, extended LF had returned and some. But of course there is more to the improvement than just LF. Sound fills the room more, there is a greater sense of the beginning and end of notes. I can follow instruments with ease, there appears a greater precision. Vocals are much clearer. The pre AUVA sound is all there but more of it with much greater definition. It sounds like the difference in listening at a gig from the crowd and then listening with headphones on the sound desk. I made a few notes when listening to some tracks I enjoy from a variety of artists, and deliberately not just the usual subjects, my comparisons are with the speakers on the Townshends.: Oasis, Cigarettes and alcohol. I normally struggle to listen to Oasis unless in the mood as the way it is mixed does not appeal to me. However. I was amazingly able to follow the bass line and get a real thump from the drums: the mix has never allowed me to do this before. Remarkably un-fatiguing!! Bar Italia, Jelsy (Album The Twits) Clearer Nina vocal, electric guitar easier to follow, bass still a bit boomy. Clearer emotion in male and female lyric. Greater detail in electric guitar, individual notes easier to follow, real sense of a drum kit and ability to easily follow the complex and unusual rhythms. I love this album and recommend a listen if you do not know it. Beatles, Here Comes the Sun More detail in the background, perhaps a more analytical sound for example, much greater detail of snare drum, bit more of bass. Nothing new, just more detail and precision. Slightly wider sound stage. Synth line much cleaner and easier to follow. I made these notes after fitting the AUVAs. Over the next few days, amazingly, I felt that the sound was improving further. Everything was getting tighter and more extended. The depth of the soundstage has increased considerably. Perhaps I am listening more intently but music appears more to be more natural and detailed. So, I decided to buy a set of AUVAs and I have sold my Townshend Bars. I am very pleased, but are there any downsides to them? Fitting maybe an issue to some if you have to drill into your speakers and fit a thread, however, if you have spikes already these just come out and are replaced by the AUVAs thread. They are big! To me they look too big under my speakers, but that is just personal preference. The extra height is OK but the diameter irritates me, however, for me the improved sound is worth it though. The cost, although about the same as the Townshend Bars. In summary, The AUVAs have made a significant improvement to my listening pleasure, what more can you ask for? Speaker cables come up through the floor and do not come anywhere near that lamp flex

Thanks so much for the feedback pete ! It certainly seems that fixing the AUVAs securely made a big difference for you. I believe, without fixing, the speakers would simply slide back and forth on the smooth top of the AUVAs - this is not ideal for minimising the cabinet movement (as intended in the AUVA design). Interesting feedback regarding the 'settling in' period for the AUVAs. I have removed and replaced mine several times now and it is obvious that, although improved, the SQ uplift is not as good straight after fitting. After a few days (maybe 5-10hrs playing music), the bass tightens up further and becomes more solid and impactful. Also, the transparency improves even further.
