Oh wow , I will text Jon Badov nowWe will bring out the 600x500 mm version of the new Reactio 2 probably in 10 days from now
Seismion - new active isolation platform from Germany
- Thread starter TLi
- Start date
Greetings Thomas, I purchased an IR remote pot form eBay, but it doesn't have enough power to rotate my pre-amp volume knob. Interested in knowing what parts you used to build your volume controller. Thank you!
We have made another video that shows the performance of active isolation versus passive isolation:
At the beginning, the automatic precision levelling is performed, after the isolator has been loaded with some weights. Afterwards, the top-plate is excited by hitting with a finger. The measurement gauge proves that the isolator is quickly oscillating in its natural frequency. The vibrations are weakly damped and continue for several periods until settled. In contrast, with the active control forces turned on, the isolator rather creeps back to its equilibrium position without any overshoot.
Quite impressive is also the fact that the Reactio 2 can handle such strong excitation. In the video the oscillations of the top-plate are clearly visible when the active forces are turned off. Still, the isolator does not turn into idle state (like some other competitor products), but continues to perform.

Which size and model of Seismion are you using under your CH M10? 50mm x 40mm seems too small.
Are you using two? One for the M10 control 53kg, and another for the M10 power supply 78kg?
I use one Seismion under the signal chassis and one Daiza platform under the power supply. I'm using the smaller 400mm x 500mm platforms of the first generation referred to only as "Reactio". The chassis are certainly wider than the platform's top plate, but the titanium spikes are positioned easily within the platforms, with ~25mm to spare to the edge.
Thank you. Good to know. I currently have a CMS Olympus Ultra platform for each unit of the M10, but plan to try the seismion.
I have the 541. My rack was already fairly well damped and isolated. (Rock maple shelves on oversized lignum vitae legs, resting on Carbide Audio bases) . I found an across the board improvement with the 541 beneath my turntable. Most notably the sound stage size and secondly overall bass definition, clarity and balls. Now, I have Eggleston Works speakers and among their many strengths is the ability to more accurately reproduce the subtleties and nuances associated with drums. Drums are my favourite instrument, not learning to play them is the regret of my life. I’ll often search out recordings that feature exceptional drum production, old Genesis, later Slayer with Dave Lombardo, or Danny Carey. Somehow the Siesmion was able to pull the already vivid drum sound out of the recordings and offer up further improvement. I was actually laughing. Big improvements , like that saying goes, can be almost indistinguishable from magic.

update on my Seismion journey, I’m excited to share that I got four new reacto 2 platforms , one of which is the 500x600mm size which can support an amazing load of up to 150kg!I worked with Jon Badov at Sonic Artistry and he actually drove down to New York and helped me set up my platforms into my Artesania Racks. Jon is phenomenal and it was a pleasure to work with him! I love my Artesania racks but they can be a bit painful to adjust in height and level , Jon was patient, precise and we figured out a functional lay out for my gear. I’ll share some pics , as you can see my space is crowded and I still have a lot of work to do . I now have 8 seismion platforms in total. The bigger reacto 2 is under my vpi avenger , I use DS audio and tru glider tone arm ; I have to say the TT and particularly the tru glider benefit immensely from the seismion platform ; sound is crisper , more spacious , the grand master ex is a very stiff one piece cantilever/stylus cartridge and the combo of tru glider and seismion platform help it glide ever so truly.
We then placed ds audio grand master eq on the reacto 2 as well. Then pre amp and msb stack ; the aurender n20 is on a standard sesimion. As are my powerzone and reel to reel . The block audio amps now can rest on the seismion plus as weight allowance is up to 80kg for those ! All in all I’m super excited and happy. I would say the lowering of noise floor and expansion of soundstage is what I notice the most when activating the platforms , the outline and texture of sound becomes sharper and crisper as well.
For Analog lovers , I would say for sure check out the tru glider tone arm (I would recommend connecting with Dr Vinyl, he will elevate your analog rig with his expertise) then for sure consider a seismion !
Looking damn good and sounding even better! very pleased you are enjoying it.
Jon is great, very nice setup. Glad you were able to get his expertise.
Now try vinyl playback with the DS ION off vs on. You may find you prefer it with it off.

We ran out of time to do the DS ION on and off. That and a couple of other things.....next trip.
Another good example of Seismion usage, there are numerous examples. Once you tried active isolation, you keep adding more.
I have 15 active platforms in my system and is still considering more.
In Munich show last May, Seismion demonstrated speaker active isolation using 8 Atlas. The result was very good. The only problem is the thickness of Atlas. It rises the speaker too much. The price of 8 Altas is also considerable.
When the opportunity comes, I would certainly like to try speaker isolation.
