Another suggestion has come from another source of applying some form of damping to the springs . A foam ear plug cut in half is supposed to be just about right . At this stage will leave it as is under the dCS pair as they are very heavy and compress the gap to the correct 1-3 mm that is supposed to be the optimum .

Will certainly be adjusting the number of springs on the two sets while they do state that two springs can be used for stability three is probably as low as you can go . Three may well be enough for the NVA S300 but will start at four and see how that goes . I am thinking of using the second set under my Mutec and that will be a three spring set up and quite possibly a three feet option as well as the Mutec is a light weight unit . All good fun things to investigate and try and for very little outlay julesd68 how heavy are the speakers you are going to use these under ? If you go to the Solid Tech website under Iso Black it has a chart to give you the correct loadings for various weights .

My speakers are only 20kg. Of course the sound will be slightly different just by way of raising the speakers an inch or so higher with these footers, so might be difficult to gauge exactly what they are offering to the sound quality.

I have found that isolating speakers gives a better depth and control to the end result, bass sounds tighter, and there is a general improvement to the soundstage and better focus and positioning of instruments, its not earth shattering just an improvement. I use Hudson Hifi Big Foots hudsonhifi.com/collections/sound-isolation/products/bigfoot?variant=42761545416902 which have the same effect as springs, they are similar to sorbothane but believe they have silicone added. Just in case of psychologically induced wishing for them to work I have removed them several times and listen with spikes, and fixed feet several times and each time I put the Hudsons back I can hear the change. 

You should get similar improvement with the springs you have with good VFM.

They probably work along the lines of Black Ravioli, which uses constrained layers. I've still not come across anything as effective as BR but my Auvas are doing a good job.

Surely your choices weren't that bad!

I have now found out that the improvement of my Tidal random selections has nothing to do with Tidal but is the result of another LMS plug-in Last FM scrobbler is the beauty . On each player I have made this the choice for when a playlist ends . As the site records each song it learns about my choices . If the last song I chose was on Tidal it will make choices on Tidal from the full library . If it was from my own music then it continues with that . Whatever the results are very much improved from Yazoo to Frasey Ford is a jump but one I would make. The longer it is plugged in the more it learns .

Martin i like to set a playlist off with about 20 of my own choice tracks and then have new tracks added . Within LMS there is a random addition that starts after the last track which then chooses songs from my own music in a random way . However if you were using Tidal when the last song there finishes Random Mix switches to your own Library . One of the only reasons for me to keep Tidal is to get new music to play and find some different artists . Using Last FM seems to do this and keeps the songs all from Tidal which is what I have been looking for as this suits me . As Last FM has now over a months worth f my random plays it seems to understand and use the wide range in its choice . Today I heard a track by Vulpeck called Funky Duck which was superb sadly the CD to buy is way too expensive but will keep an eye out now for any ones at a sensible price .

Good morning all and it is indeed a good morning . Woke up and went to the bedroom with my three way in it and there was the sound of Cascade having been running most of yesterday and all night . Start some music and the smile arrives , yes this is sounding very good now back to what I remember it before I stripped it down to swap stands . Bass is now excellent and sound stage is wider than I recall it was . Soundstage on this system was never one of its strong points as it is sealed baffle speakers hard against a wall . Active helped this and now it is actually very good , with the right recording they do make a very good job of throwing shapes behind and outside the speakers . Big relief for me now as I know this is working well and sounding at a level that I am very comfortable at letting others listen to it . No this is nothing even close to a perfect system and there are things that could be better but Boys are back in Town starts and I forget all that and just about reist the temptation to get out of my seat and start bopping about (trust me no one wants to see that least of all me) then the twin guitar solo starts and the smile on my face is a mile wide with sheer joy at the interplay and rhythmic dancing of the notes . Active does impart that real sense of speed in music the incredible stop and start of notes which so far I have not heard in any passive speaker . I find it addictive and miss in other speakers . Quad ESL is the nearest which is probably why I use them . Now just got to keep playing this every day until the show and hope nothing goes fft . Still need to do another DIRAC Live session but not screamingly essential . Also considering giving the Digital CR a tweak and making these two and half way rather than the full three way they currently are . Suspect it may well increase the overall bass but not quite sure . That though is for another day .

Three or four supports seem to make a difference on my systems too

Not always three and not always four
