PLEASE SEND ME A PM IF YOU'D LIKE TO TRY SOME DEMO STACK AUVAS.
LINK STARIGHT TO THE REVIEW: audioaddictsforum.com/post/96312/thread
I have been meaning to investigate some isolation for my Vaders for some time. They are currently spiked through carpet on to a solid concrete floor. I know Townshend bars will improve things, however, I am not so keen on the speakers being so wobbly and it is hard to dial in the tilt and positioning. Although, ultimately the best sounding solution will prevail. I have read a few reviews about the Stack Audio AUVAs and am keen to know how they compare. Many anecdotal reports prefer Stack Audio to Townshends and Isoacoustics, but the proof is in the pudding. I am now looking at designing some nice outriggers to suit a range of speaker widths too. Stack Audio will be sending me a demo set of AUVAs so I shall be testing them and reporting back. I'm keen to hear them vs the Townshends too. Watch this space...

I am certainly curious. The smaller 50s are pretty reasonably priced too and take speakers up to 275kg. The 70s and 100s seem to add more isolation/absorption. |

Have been down this route many times, all of the devices had strengths and weakness, especially if you on an upstairs suspended floor.
Personally I do not use Townshend any more, for a couple of reasons, they work no question and in some instances are the only solution for the location imho.
Have tried the stack for the cost they are benefical, a good alternative to the usual suspects, not for me but for you maybe different.

Do you have any alternatives I could try? |

Based on the reviews and literature, I'd think you want to test the large ones for maximum sense of what they can do. Ideally, they'll send all three so you get a sense of where your personal tipping point is for performance.

There are many factors to consdier here, also the speaker wieghting itself as most are front heavy being driver orinitated in that area. Location material, what amount and type of vibrational control you are look to achieve, energy conversion / dissapation or absorbtion. Its about assessing each speaker location and how best to address the vibration control in those circumstanices Jason, you may find that you could end up using a couple of different stratagies to achive your desrided results. Testing is abolsute key here, something I know which you will undertake dilligently  |

look forward to your thoughts , having tried hundreds of speaker options over the years i always follow it including townshend , iso acoustics 6 types so far , sonority design and multiple others
what i like about the gaii is they come with 3 different types of screw adaptors which meant i could use with my verity rienzi which have 1/4 screww in brass feet . Cant see that with the stack
actually although the gaaii made a difference in cleaner top end i prefer the mellow sound of the current iso acoustics 76

Too small for my Vaders and I require open space underneath for downfiring bass drivers. I wonder if the feet unscrew from the platform and can be mounted directly to the cabinet underside? You might want two additional feet though. |

Perhaps misterc knows how I can set of 8 for demo/testing? |

The Track audio isolation devices are available seperately in the three formats that have been discussed in the thread, each set come with either a meteric or imperial set of of ultra high quality stainless threaded inserts 6/8 & 10mm adapters or the equivlent for UNC & UNF for the over the pound supplied big bangers. Everything is made in-house. Until you actually pick one up and hold one, you will do appreciate just how good ther quality of the engineering really is.
Levelling up speakers or setting a down angle for those hot tweeter models is simplisity itself, one turn of the thread = 1mm, precision screw cut on a rather special 5 axis machine. They are manufactured from areospace stainless spec material, each device can cope with 100Kg each.
Dialling in the speaker set up is a breeze, if you are citing on carpet, the use ther small dome model, speaker is just so easy to manuve even in very small increments to dial in that sweet spot. If on a hardwood or concrete/marble foor then use the large domes to the same effect.
As far as looking for loan sets, Track audio are part of a much larger company Track Components and that operates a pro forma purchase situtaion here in the UK, they also manufucture other speaker companies products are well.
Even we do not have an account with them, we sell around 30+ set a years
Currently delivery time is between 3-5 working days, yesterday they informed me that they (the audio side) are on an anaual leave until next Wedensday.
Full set of four small dome metric isolators with adjustment locking tools
The quality of the engineering is absolutely first class, puts some much of the other alternatives to shame imho
Large dome exploded view

Really useful information, thanks Tony. I shall try to get a set for Audition. They do look extremely well engineered. |

Fantastic stuff.! Of all the changes I’ve made of late, adding outriggers and footers has made the most difference by a country mile. Currently enjoying Gaia 3’s… but aiming to explore alternatives and particularly the Stack Auva’s. Mind you, the current outriggers remind me of something….   |

I've emailed Track Audio to enquire about trying a set. Hoping they'll respond after annual leave. |

I kind of wish these weren't so good 😂😭! Not cheap, but pretty convinced tbey're making a very noticeable difference. Is the difference commensurate with the cost? Annoyingly for my wallet, almost deffo! 😂😂😭. No snap decisions though, more listening and many more comparisons to do. The next few weeks will see the Vaders sitting on Track Audio, Townshend bars and hopefully Audite platforms. Many more ears will be listening too - it won't just be me reviewing. Initial (very obvious) differences... Bass was epic and now it's obscenely good - can't stop smiling. Vocals cleaner and more present and soundstage is an immense, deep and immersive experience. I'll write a more in depth review of various options and others will listen too. Stay tuned.    |

@arke Obviously the speakers are now 2 or 3cm higher with the Auva's in place, do you think that has made a difference due to the downward facing bass unit?

I shall sort some (thin) metal outriggers next week and will test the speakers raised up (without pods) too. Tweeter/mid alignment has been maintained by changing the tilt. If the uplift in SQ is ONLY due to raising the speakers that'll still be a big win! I shall sort some measurements too. |

Those are the 100's I assume. I suppose you can try the 50's next to see how much of that effect you lose for the lesser price. :eating popcorn:

Great shout. I am not someone who likes going blind on hifi decisions, so having the opportunity to compare various options is great. A few others from the forum should be joining to offer opinions too. It won't just be my ears. |

Jason don't laugh but I will soon have eight spring feet similar to the nobsound ones you can find on Amazon and eBay . While these are nothing like as well made and effective as what you are looking at they could be used as a base line control as they offer a simple but effective reduction in vibration between the floor and speaker . If you would like to use these to experiment with them get on touch and will get them to you some how . They are on the way to me currently but I am away on holiday for a week from Tuesday 6th so might need to be after then .

bencat I'll have a laugh then Andrew. I wouldn't like to be balancing nearly 70kg of floorstander on 4 of those, I do have a set of 4 which I'm hoping to try under my amp, but using a bamboo board between amp and springs. Seriously, a nice thought, I'll leave it up to Jason to decide, he may come up with a way to facilitate their usage. On another forum someone made up their own Townshend springs and somehow covered the springs with a rubber tube.

Post by bencat on Jul 27, 2024 12:33:30 GMT
Dave truthfully they need lots of weight with a full complement of springs and need something really heavy to get them to reduce to the right level . They also have some sort of sticky finish to the bottom that once they installed keeps them very much in the same place . As you have noted they are able to be further added to with inner tube covering them which damps the movement . I love what they do in three figuration with only three springs under equipment . Not really tried them under speakers but may well give them a go under my stacked KEF 103 to see what they do . This is why I bought them but quite happy to let Jason have a play with them if he is interested . For my speakers I find the Aircraft Antivibration mounts to work more effectively as they used opposed springs which seems to have better control . Difficulty now is finding any at sensible prices and the limited weight they can handle . Doubt any I have seen could handle Jasons speakers but they work well with my Quads .
