Any fans of Symposium Acoustics here?

[Asamel]

Do they have a dealer in the US?

Yes, many dealers, and they sell through Acoustic Sounds too. They also sell direct..feel free to give Peter a call.

Andre, spkrs are not too difficult to adapt to Rollerblock Jnrs, but to begin with, have a spare pair of hands when it comes to spkr tilting etc.
I actually have each corner of the spkr baseplate resting on a half cup, then the ball bearing, then Svelte platform. The combination is great inasmuch as I can reas easily change toe in etc by moving the whole shelf w/spkr sitting on top.
I'm sure the combination of discontinuity-continuity is what gives the change it's positive nature.
Asamel, do contact Peter, his replies are detailed and ultra helpful, a breath of fresh air in this industry full of, tbh, quite difficult characters.

Thanks for the tips. A second pair of hands it is.

Agree about Peter. No bull, and excellent advice given.

I did it on my own, but depending on the weight/centre of gravity of your spkrs, that extra person could be invaluable.
I believe it's essential to have a thin shelf on the floor to put the spkrs/Rollerblocks on (Svelte Shelf ideal, and this is indeed how Symposium advise, 2 layers of isolation as result), so that you can move the whole shelf/spkr as a unit re toe in etc. But might not be poss if the weight starts to exceed 120-150kg (my Zus are under 100kg so I'm ok here).
Remove one spike at a time, insert either the whole Rollerblock Jnr item (so that in sequence top to bottom: spkr-top cup-ball bearing-bottom cup-shelf-floor) under one outermost edge of the bottom of the spkr, or "half" (exclude bottom cup). Carefully prop the spkr on this single support, and then replace the remaining three spikes in sequence, Rollerblocks one spike at a time. Being extremely careful not to asymetrically load the Rollerblocks so not to have the ball bearings go flying (more an issue in my set up where I'm not using the bottom cup).
You'll know you've got it right when the spkr sits there totally stable, but a shove to the side sets up a short lived wobble - only to be done on an alcohol free day !

Yes, TWO layers of isolation is exactly what Symposium recommends if possible. All good tips above, thanks again.

I think the key is to find that point of stability as you say, so you can rest easy and enjoy the music with out the fear of any crushed pets or smashed tweeters.

I'll give credit where credit is due. I owe my interest in vibration control to Peter's Symposium. The RBJrs under a mid-line Arcam player was the first time A/B was so easily audible. I may have moved on but I still have sveltes and RBJrs on hand. I could never bear to part with them. They work. I don't think there's more I can say.

Jack, you nailed it. Perfectly said..where were you when I was writing the review?

Probably in the office trying to figure out why importation has become so friggin' expensive under our current administration! LOL!
