Symposium Ultra Stealth top I'm using this under my TW AC3 with all BN upgrades with wonderful results.If you want the best this is the way to go good luck.
Turntable and Rack vibration control
Hi,
I moved from a Nouvelle Platine Verdier to a Loricraft Garrard 301. The big change with this move was that the Verdier comes with a terrific implementation of pneumatic suspension feet which kept the TT almost floating and hence great isolation from vibration. The result was always a noise/grain free playback and super clean backgrounds. With the Garrard, the plinth is typical custom made stacked birch ply with standard steel cones as footers. When placed directly on the rack the background is noisy, the images muddle up and overall music is not well sorted.
I do not expect the Garrard to be as quiet as the Verdier but I know it should not be this noisy either. In fact the Verdier also sounded noisy when I placed it directly on cones bypassing the pneumatic suspension feet.
I use a Hutter Racktime rack which is not like an overbuilt audiophile rack. It is more like an open frame rack with lightweight supports. It is a bit like a Rega TT, not very damped or controlled. The rack has pointy steel feet which rests on brass spike plates (mine is an wooden floor). I guess this implementation is not sophisticated enough to keep away vibrations and let the TT play quietly.
I am looking at two levels of solutions:
1. Replace the existing steel feet and brass plate with a quality vibration control footer below the rack
2. Replace the stock steel cone below the TT plinth with a better footer/platform.
I have tried Sorbothane, Squash balls kind of tweaks, while they reduce noise they slow down the music too.
I have also tried Stillpoints and Finite Elemente footers under the rack. They make the sound thin and metallic IMO. Platforms like Minus-K are too expensive so I have not considered them yet.
I am looking suggestions here, probably footers and vibration control devices that are more musically oriented yet well engineered like Shun Mook, Harmonix, SSC or something like an HRS platform ?

Racks per se can and do exacerbate structureborne vibration thus it makes more sense to skip the rack entirely and place the component of turntable whatever direction on a competent isolation stand on the floor, of course paying attention to how the component or TT is interfaced to the isolation stand and how the isolation stand is interfaced to the floor, preferably with extreme hardness cones. On the grand scale of things even tempered steel is not nearly as hard as say the special ceramic ones. |
Thanks to Raul I learned about ''Pneumatic footers '' from Technics. I use the AT 636 version for my Technics SL 1000,mk2 (Obsidian plinth) which was provided with mediocre suspension. There is even a bigger version for the very heavy TT's which Raul uses . I would ask Foxtan ( [email protected]) if he has ''some'' in stock. As far as I know ''the best there are''. |
