Seismion Reactio Plus

[Kvali1]

@Kvali1 very helpful, how did you find the improvement under the 6SE ? Thank you.

Hi! With my tube pre amp , I did some careful a and b listening with turning it on and off , the change is subtle but I do strongly believe it is real , there is more separation of instruments , I do a lot of jazz listening both analog and digital and it just seems dynamics and separation is better . I know the term is over used but blacks are blacker and I think that helps with bass control. I do suspect that tube audio gear benefits from these platforms significantly . I don’t know if I can tell much just yet for the one under my aurender n20 but finances permitting I will purchase more Seismion and place them under all my gear… a lot of time is spent discussing footers and for me I much rather spend money on active isolation and Seismion does it really well.

I had a nice improvement from placing Wilson Pedestals under my Ref 6SE.

I'm highly interested in buying multiple units of the Seismion Reactio plus, as a replacement for the HRS M3X3 isolation bases which I'm currently using.

The M3X2 Isolation Base is the latest generation of reference level isolation bases from Harmonic Resolution Systems.

However, the four feet of the Seismion Reactio plus look rather angular, plasticky and (possibly frail) in the online product catalog renderings.

In the photographs of the actual product seen on this WBF thread, the foot's upper portion looks like cast iron, and the disc on the bottom appears to be some sort of elastomer (or rubber). Some photos show these feet to be partially "hanging off" of the edge of component rack shelves which are just barely large enough to fully accommodate all four feet.

I've never seen the actual product, so I can't really comment. Do they have any vibration reduction, or isolation features? How do they couple to the base? Is there a threaded post which helps the feet be levelled?

Owners - please help describe the feet - what are the pros/cons? In what way do you think they can/should be improved?
Dealers - please comment on the design, and why the current feet are optimal. Any plans for replacement feet, or upgrades?
Thank you!

Hi! Ok, yes, so Sonic artistry offers replacement feet that are 150$ and according to John Badov at Sonic artistry they work very well and are a upgrade ; and or you can put isolation footers under the platform , I’ve done isoacoustic pucks for example . Currently two of my seismion are on the artesania rack that is designed to have footers instead of shelves and this is working well. My Seismion under my TT is still on its original feet and working just fine .. all that said the new reacto 2 is self leveling and I think it actually benefits from resting on its original feet. If you’re in North America call John Badov at Sonic artistry in Toronto , he’s super honest and excellent.
