Sorry Marc for a strongman-type of an experience
but our quality mass is a part of the damping mix.
Cheers,

Jarek, v glad to fly the Stacore flag
It may be hard to believe from my words, but I went into the active v passive comparison strongly expecting active to win out
1- the data on sub 3Hz and sub 1Hz isoln suggested it
2- the findings from Mike Lavigne and Christian Rockitman have been nothing short of stellar
3- my week long trial just with the active Kuraka was wholly positive
4- the effort of getting 95kg 20' up my 40 spiral steps enough to make me curse Jarek LOL

So for me, it was a truly amazing suprise for the passive Stacore to be not only better than active Kuraka, but better by a large margin, across more range of attributes, and critically beating the Kuraka at its own game ie even better in the bass, where all the positive reports on active contend its superior
----------------
And a real pat on the back to Jarek and the team for going outside the box, and concentrating on getting the broadband isolation concept right, because I truly believe it's the Stacore superiority here over active isolation that really does make their approach vastly more superior for our audio needs
Did Stacore develop these platforms exclusively for use in high end audio, or are they being used to isolate devices in other industries?
Marc, Thank you for your continued reporting.
#2 is interesting given your "world's first" perspective. I tended to believe the much discussed advantages of active isolation based on the reports and graphs, just like you, but I could not know for sure and a few people did email me suggesting that my Vibraplanes may not be inferior to active platforms, so your thread has proven to be quite interesting to me.
Do you know if Mike and Christian ever did direct comparisons with passive devices? I don't seem to remember any such reports which make your impressions that much more relavent. Marc, are you suggesting that passive isolation in general, and the Stacore in particular, is inherently superior to active isolation for use in high end audio due to its broad band approach?
Did Stacore develop these platforms exclusively for use in high end audio, or are they being used to isolate devices in other industries?
Peter, I'm assuming Mike and Christian didn't a/b Herzan v passive
All the energy on their explorations in those Herzan threads never mentioned comparisons, just that the Herzan demos slayed their standard racks at the time
And Stacore was not available then, Vibraplane was discontinued, so Herzan had an open goal to aim for
Now we have Stacore, a unique product on the market pitched in price at the mid point between passive Minus K/Speirs and active Kuraka/Herzan/Accurion (Halcyonics), and with the Kuraka trialled at an ex demo price competitive with the Stacore, and performance commensurate with the Herzan, the trial commenced
All I know is that if the outcome of my trial is anything to go by, I would urge enthusiasts to seek a trial themselves
It might be in other systems and other rooms that active might win out, but in my system and my room, the Stacore is decisively superior
-----------
Regarding broadband isolation, however Stacore are achieving it, it's real and very relevant, and as I say just where you "expect" the Stacore would be inferior (because the specs/data would strongly suggest it), it absolutely is not, despite first impressions being somewhat misleading
And it looks like it's a true blend of the pump isolation, uber mass loading (my stairs! MY BACK!!!), and CLD constrained layer efficacy, that is achieving this
--------------
Re combining active with passive suggested by Murphys33, I'm sure this is trying to replicate Stacore's broadband approach
But since I'm stretched to the limit contemplating Stacore'ing out up to 8 components, it's totally no go for me to even consider for a second a solution 2.5x the price
And to be frank, Taiko Tana works out the same cost wise as Herzan or Accurion plus Symposium Ultra, in an all in one combined product, so why bother?
Cost and other reasons preclude me even thinking about Tana, Mike Lavigne is your man here
My mistake?
I thought it's n/a
Sorry to misinform
Tbh, a continued story I hear re Vibraplane is of maintenance issues on used items, and beside that I suspect it might be impossible to trial in the UK (I only trialled Stacore w the promise of sale or return)
Peter, maybe you need to ask Mike and Christian why they didn't a/b the Herzan against the Vibraplane, I can't offer any hard facts here, but I'm surmising they were sold on the sub 1Hz isolation data on active lab grade platforms, and their choice was Herzan, or nothing at all
And I put it to you that the Vibraplane has the same deficit in relation to Stacore that active platforms have too
That is, it's a lab device w no pretensions for audio use, and no ground up design w audio use solely in mind
So it's a series of pumps (like Stacore) with a straightforward steel chassis (unlike Stacore)
And according to Jarek, the air pumps start the isolation phenomena off, but the constrained layer tech, mass loading, and Rollerball lateral isolating seperate top plate, with whatever "secret sauce" mix of materials they're using, is where the real magic and superior performance comes in
Please don't take my comments as disrespectful to Vibraplane, I'm just trying to read between the lines/join the dots
I think that the technology of various active devices such as the Kuraka does vary. on the surface one might assume they all have equal effect, but unless you actually compared them you might not know. I wonder who makes the Kuraka? maybe it is OEM Halcyonics?
Stacore a no brainer, performance AND cost
Adam, yes the top slate plate of the Advanced indeed is on Rollers, but the component itself must really not have a compliant contact
It'll be the difference between success and failure
I believe Jarek's colourful term was rubber footers "castrate" the Stacore!
So, floor or absolutely inert spiked stand (with no integral wobble, Rogoz good, my Symposium bad) > Stacore > hard footer > component
Marty, what are those new spkrs of yours again ???
