I am considering this as an alternative to using stillpoint ultra 5's under my turntable. My table is non suspended and weighs around 125lbs. Experiences ? TIA

I say go for it... as you know i have the HRS M3 under my Transport, and also use Stillpoints elsewhere. Brinkmann used to sell their Ref turntable with a custom HRS M3...they now use vibraplane i heard but am not sure? That said, I do know someone who just bought a Brinkmann Anniversary TT, and it came with an HRS M3.

I have not compared my M3 to Stillpoints Ultra 5s as a base under my Transport...and frankly after so much back and forth may not bother for some time. I am extremely happy with Stillpoints for speakers and sub...and HRS M3, nimbus/coupers under my components. (On top of components, i do have damping plates from Artesania, HRS and Stillpoints (their Ultra V and LP Isolator)...and they all work well.)

There are three passive units that I would consider Christian: HRS, Critical Mass and SRA :) I've actually been thinking of trying to compare the SRA with the HRS under my table some day but that'll have to wait until I get my new table :) One advantage of the HRS is that it's compatible and easily tuned to work with a range of gear while the SRA is configured to only work with one specific component.

Doesn't Clearaudio make it's own base? But I guess that's a lot more expensive than the HRS.

If you do compare...definitely please post!

why not a vibraplane


I have thought about it. The compressor in the same room may be problematic. I may be able to punch a hole in the wall and locate the pump on the other side. My only other concern....it's a product designed for scientific use, not for audio. That said, I do like Peter A's setup for his sme

They don't make a base. They do make an entire stand for a turntable....the Everest stand. I guess I should look into a vibraplane.

I'll email you the info Peter sent me on the Vibraplane and the compressor. Peter says the compressor can be placed next to your rack. It's that quiet.

Thanks Frank. I want to move in this direction. Please include the retailer that has all the stuff....table, weight plate and compressor.

Isn't the fact that the vibraplane is designed for scientific work a 'good thing' ? Scientists have to do real things that matter, and they use equipment that works.Of the items mentioned in this thread, the vibraplane is probably head and shoulders above the others. But I agree that the pump is a bit offputtng; mind you, it will be 'off' most of the time won't it. The pump only tops up the air when needed. The biggest disadvantage, at least for me, is the high cost. Best bought from a scientific equipment supplier rather than an audio supplier with big mark-ups.But scientific gear will never be cheap. I am tempted.

you took the words out of my mouth. They design vibraplane for electron microscopy which is about as detailed as anything audio

yes too both of you. I was playing devil's advocate to elicit that very response. My next issue is to figure out if my Adona Zero GXT rack's top shelf can support 400lbs. of total mass for turntable, plate and vibraplane. My rack specs say 300lb shelf capacity, but the top shelf is supported directly on the pillars rather than floated on brackets like the lower shelves that have a 300lb weight spec. I hope it takes more.

According to Peter A, they work great under power amp too..cha-ching !!!!! ;)

I'm with Myles, HRS, CMS and SRS. There is one instance where I think I would go with the vibraplane (or a sprung suspension deck) and that would be if I were in a situation where I would get a lot of vertical forces from the floor. I'm engineered wood on concrete. Shaq could be doing the jump rope and I wouldn't get any bounce. CMS uses a combination of acrylic/bitumen-like sandwiches, mass, elbows (bearings) and spikes. There's actually more than 6 different materials with opposing Qs. Works extremely well for me. What I like about the three mentioned is that they do not alter the tonal balance like some others do. Forgive me if I will not mention these, that would be in poor taste.

I'm on solid concrete and I can jump all day without affecting the turntable. Aren't the vibraplanes about eliminating that and also (more importantly) airborne vibration and in our case vibration caused by the music playing ? Passive isolation cannot deal with that can it ?
You definitely need one under your AF1 Jack....;)

The airborne vibrations is more about quickly converting the energy to heat. I'm not too familiar with the top plate of the vibraplane but if I'm mistaken it is a solid aluminum plate. Aluminum has great damping but it can still ring by iteslf. Usually you want something softer or something hard with a damping layer or a material with specific damping properties like acrylics with particular grains. So far the best I've ever heard use combinations of materials for constrained layer damping same way your table uses aluminum, acrylic and panzerwood which itself is a combination of woods with different densities. Same goes for the best footers like the Stillpoints (aluminum/ceramic), Symposium (aluminum/tungsten), Magico Pods (aluminum/polymer), Walker (Brass/Polymer), RiZE (Aluminum/Polymer/Titanium) etc.

I often see electron microscopes referenced and it is really hard to argue with that so I won't. It just makes me wonder about what the differences are in the environments an electron microscope is used and that of an audio environment. I mean I don't think EMs are used in places where it would be subjected to the levels of airborne vibration like that you would find in a listening room with music playing. Most labs are pretty quiet. The isolation I would assume would be engineered more towards very low frequency seismic and other ground borne vibrations. I have no doubt a vibraplane would do an excellent job. I just wonder if it is as good at audio as it is for what it was originally designed for. I'm not curious enough to find out for myself.

'Cept they don't use these "toys" for EM scopes :) It's more like a specially designed, one ton platform on active, air suspension feet. And it's not always successful either as they found out at Columbia. (Of course, are the frequencies affecting EM scopes the same as tables?) Despite their best efforts, the trucks going by on Amsterdam Ave. affected the scope's imaging. They eventually had to move the instruments elsewhere.
