Isolation for a table for floors with movement

Hi Chazzbo, thx for the info.

I have been looking into Vibraplane, Halcyonics and Minus K product.

One of my thoughts is to use a ridget stand, place 1-2 inch pce of slate, then place one of those above isolation pces on top of it and then a SRA stand on top and finally the TT sitting of it. I just don't want to be fussing around with anything once it's all set up, some isolation pces needing to filled periodically.

A member "Cello" has as similar set-up and below is what he had to say;

"In my set up I am using a Minus K with an SRA Ohio Class stand sitting on the Minus K with the TT sitting on top of the SRA. Both pieces separately are well worth the effort and the cost."

"The combination of the two is more than twice as good as either piece separately."

"In my set up, the Minus K does more alone than the SRA does alone."

"The Minus K eliminates anything coming up from the floor while the SRA helps to drain resonances coming out of the TT (which are significant)."

Lots of info Thx, here's a little more info. It's in a living rm set-up.

When I had this house built over 11 years ago now I never intended on having a table upstairs. The floor construction consists of 2 layers of 3/4" ply on top of resilient joists. The top layer of ply is also screwed into the joists and then every other 5". The floor isn't that bad but when we are talking about movement there most defiantly is such and adding a table I want to address this properly so not to have any issues.

Underneath is a basement with 9ft finished ceiling, open concept so I can't do any post etc.

When I went to the Minus K web site and viewed the video of the glass of water and coin standing on edge looks pretty impressive. I like the ideal of what one member did by placing the SRA platform on top.

What are your thoughts if I just use one of my current stands which is a ridget design and then place a 1-2 inch pce of slate on top, then place one of these vibration platforms on top of it and then for example lets say the SRA platform specifically designed for my table and finally my table on top?

Let me know what you think

Thx for the info.

My MBL 101E speakers are placed on Sistrum platforms.

Are the HRS stands really that good and the answer? They appear to be a ridget design, I wouldn't want to spend all that money and then have to still use on platforms etc.

What you guys think of doing this;

Remove the drywall below on the ceiling and box the joist in with plywood and repair. Then from up stairs remove enough finished flooring material and drill a hole in each joist run and pump in concrete. The joist are 12 inches so I could make it what even.

The joist are on 16 inch centers and my speakers are 6ft from the back wall so I could do say five runs.

thoughts on doing this

Hi Artemus_5 Thx,

yes they are I-Joists and I would have used re-bar etc. in actual fact I would have had a engineer tell me exactly what to do. Forward, I spoke to my friend who is an engineer and there is a way of doing it but other issues could arise down the road so I have decided against doing it.

It's been a while and wanted to update this thread. Unfortuantely due to the design (open concept basement) I could not do any upright support post so I did some further research and .....

I purchased a custom made Minus K platform, works great!

I know longer have the TW Raven One table, I went up the TW food chain to a AC3 and now I'm a proud owner of the Black Knight.
