    Default Soundeck by SDS 285 stainless platter mat for Technics

    How's that sound? Is 285mm a reasonable size for the mat? Unfortunately the next thickness available above 5mm is 10mm which is probably a bit excessive

    does anyone know the sl-1200 spindle diameter? I've misplaced my calipers...

    edit: the Timestep EVO uses a steel MJ-12 mat, which apparently measures 295mm according to the oyaide website. Won't that go over the outer ridge of the platter?
    Hi, I have stainless steel platter mats which have constrained layer damping built in which removes vibration by converting any vibration or rumble into negligible heat. They get superb reviews, take a look at http://sounddampedsteel.com/hifi.html and email me if you want to test one, if you don't like it I'll refund fully (less postage cost). Cost is £90 plus £5.00 postage. The 285mm weighs 970grams, there is also a 295mm version. They measure 2.2mm thick, one layer @1.5mm stainless +65microns of visco elastic polymer+ 0.7mm stainless. Here's a video link to a demo of it absorbing massive vibrations. http://soundeck.bigcartel.com/about

    Good luck... Les Thompson

    Must say your SDS platter mat demo video is impresive

    From your older thread (2014):

    >I can supply SDS steel to individual requirements either as a flat sheet or cnc'd to precise drawings.<

    Hi Les,

    I am interested in some parts made of SDS for my project that are not commercially available through your sounddeck web-site. Going by your older posts on AOS and this one you are also in a position to offer "customized one-offs" as a service...?

    It made it look nice going round, this was mine.

    I'm convinced it ruined my Delos though as my Rega arm at the time had no azimuth adjustment so when I moved the Delos to my LP12 one of the chanels had low output, in the end I had to buy a new one.

    I don't really understand high level math´s but physicians told me this:

    All materials have their own resonance frequency. To dampen resonance a sandwich construction of different materials with different resonance frequency´s is the way to go!

    If building blocks/plinths for electronics to stand on the electronics should be coupled to the block with spikes etc and block it self should be decoupled from the floor/shelf underneath it.

    All materials do have their own resonant frequency but you don’t need to laminate different materials together to damp this resonance. Indeed, the danger is that you end up with a lot of different resonant frequencies but with their amplitude reduced. SDS use proper constrained layer damping where two pieces of similar material are bonded with a viscoelastic compound of specific thickness. Such a method is extremely effective at suppressing that materials natural resonant frequency - more so than laminating different materials together.

    I wonder how one would measure the resonant frequency of a block of Sorbothane?

    Presumably it would act as a rigid solid at certain frequencies, high ones I'd guess.
    It is impossible for anything digital to sound analogue, because it isn't analogue!
