@folkfreak Thanks for the recommendation. Your TT shelf is amazing - nice work! You should market it.

Looking for turntable isolation advice
Greetings from Oregon,
Was hoping to get some suggestions on turntable isolation for my particular situation. My setup starts off with two strikes against it - suspended wood floors in my apartment and the turntable between in the speakers. Neither is ideal, but that's the room I have. As it's an apartment, structural changes are out of the question. I have a VPI Prime on the stock feet, which are a nice step up from the feet on the Traveler that I had before, but I'm not sure about their ultimate performance.
For my stand, I am using two heavy duty (about 70lbs. each) Sound Anchor speaker stands facing each other with a 4" maple platform on top of them (with blue tack between the stand and platform). The stands are spiked into Herbie's gliders. I find that all of my stands sound better on the gliders or generally decoupled from the floor. The speaker stands are only about 10 inches wide but the platform is 24"x19", so it's probably not the most stable set up. I'm getting good sound, but I know that the table is still subject to some vibrations. I'd like to get advice on anything that I might do to better the performance of the table.
I've considered some the following:
1). Aftermarket footers for the table, possibly Stillpoint Ultra SS.
2). Better spikes on the stand - Gaia, Stillpoints, Track Audio, etc.
3). Paving stone under the stand
4). All of the above
5). A wall shelf. This would be a big task as the table weighs close to 60 pounds. The only commercial turntable wall shelves I've seen hold 40-80 lbs. max weight, and I'd like something that is rated much higher to be safe. I guess I could try a DIY project. Would love to get the maple platform on brackets on the wall, but that would bring the weight over 100 lbs.
So, any thoughts would be welcome. It's turntable only rig, so I'm trying to wring every last ounce of performance out of it.
Thanks so much for any insight that you might have.
Cheers,Scott

not mine I'm afraid, the work of Alvin Lloyd at Grandprix Audio https://www.grandprixaudio.com/products/brooklands-wall-mount-isolation-system |
wall shelf won’t help if you need acoustic isolation (air); will help some if you need floor isolation, and the latter sounds very likely in your case best type of wall to use would be one that "floats" separately from the floor... (for your future built to spec. home) You can make one that works better than the Brooklands by using Heim joints, but it will be a lot uglier I don’t suppose I can convince you to put it in a separate room (like a closet)? |
@smrex13 - over the years I’ve tried a few things including butcher block and Maple and found they were not as good as MDF. Here are a couple of things you could try with MDF 1. Get 4-5 sheets of MDF cut to size and insert the rubberized drawer liner between each "layer" of MDF (see link below). - This approach is very similar to earthquake footings used in building construction in the far east. - Each layer of MDF/Drawer Liner absorbed vertical and lateral vibrations and transfers less vibration to the next level up as it approaches the top layer - for aesthetics, the top layer can be granite on a layer of drawer liner - the TT can sit on spikes, directly on the granite I do not have a serious vibration issue so I use a single layer MDF directly onto the stand, with pieces of sorbothane between the stand and the MDF - then a layer of drawer liner then a granite shelf on top - see http://image99.net/blog/files/3b1e019ed6bce1eec35dad4636fd815c-25.html I did experiment with a top layer of MDF, but the granite is nicer to look at and can take the spiked feet The drawer liner between the MDF and the granite prevents the whole assembly from vibrating like a drum - a common issue with granite slabs You would have to "tune" the assembly to your TT - too many layers can deaden the soumd - too few will transfer vibrations to the TT - you should not need more that 5 2. Glue 4 or 5 pieces of MDF together into a single slab - use three spiked feet to support it - use a layer of drawer liner and a granite tile for the TT to sit on The transfer of vibrations through a picve of MDF this thick will be minimal the layer of drawer liner + granite will on top prevent the rest from getting to the TT When my rack was sitting on hardwood floor I used hockey pucks with felt feet under each leg lf the rack. The rubber used in pucks is about as inert as MDF, so they transfer very little vibration I’m a DIYer, so in place of spike I make Ball Bearing feet... http://image99.net/blog/files/0915f27ce41639dc6e4bf13bff2cbcbb-24.html The advantage of these feet is that they absorb both vertical and lateral vibrations with ease and do not transfer them to the component I now epoxy the ball bearing to the washer to prevent them from rolling away You might think MDFis not that attractive, but with a little time and effort it can be made to look quite professional. e.g. see my TT http://image99.net/blog/files/04fdba8476cfd21bdd7a5fdf38c8cdf5-28.html Hope that helps |
