WMP-1A MKII Magnetic Levitation Platform audio table:

Or as I like to say it, floating on air.

It actually looks really nice, there is 4 or 5 models, including it being the top of a 3 or 4 tier stand. If the wife likes real walnut as furniture then it gets a 10 :) I like what it does for isolation, it was big hit at CES for us.

Air :) No physical connection.

I had a customer order platforms awhile back made out of black walnut, very rich looking wood!

How much weight can it support?

how much clearance between the upper magnets in the housing?? or are there magnets in the side to keep clearance of the housing?

I have been experimenting with magnets for a while making levitation platforms, they can be very tricky to center,

but I would love one of these rigs,

cheers,

Bryan

The magnetic repulsion based isolation of the stand/platform here is only in the vertical axis. The little guide rollers at the four rack corners pictured in the topmost pic found in Ian's opening post do not permit horizontal movement and thus still provide a path for vibration to move between the base and the gear support platform. The SAP Relaxa magnetic levitation platforms shared the exact same flaw. Although I'm sure this platform design offers a reduction in mechanical vibration transfer, as pictured it can't honestly be claimed to eliminate it. To do so one would need to figure out a way to use additional magnetic repulsion units to control horizontal motion as well and thus eliminate the requirement for a roller guide. I believe Clearaudio offered sets of magnetic isolation pods that somehow managed to avoid this problem but I've never met the Clearaudio devices in person or discussed their effectiveness with an owner.

Happy Trails!

My CDP sits on a wood shelf all on its lonesome and my pre sits on what used to be a 1/2" maple cutting block.
Can't say for sure if either makes a big difference.
My turntable sits on a Target wall shelf,now that made a big difference.
Q: If you kill all the vibration don't you also kill some of the music?
I've heard mega-buck systems where vibrations were controlled to the point of leaving the music flat, detailed but no jump or involvement.

one needs vertical and horizontal repulsion, the hardest part I have found is the strength and repulsion force to be enough in oppositionto hold things in alignment,
I have been fooling around with magnetic footers YEIL M&C from korea they seem to work with the right load, I still would like the one Ian has pictured, real class for a turntable for sure,

Hmmm what can I trade ??

you would need magnets on the sides as well to hold it all in place... that is the only way it would not be touching anything... but then I wonder if it would have movement while floating... or if kid walked by while rubbing his head with a balloon the extra boost of static would blow your turntable 6 feet into the air.... :lol:
