A wall shelf is probably the best available mounting for a turntable; preferably securely anchored to a load-bearing wall. For a suspended sub-chassis turntable like your Thorens the shelf itself should be as lightweight and rigid as possible (your bamboo cutting board is perfect) and decoupled (not fastened tightly) to the brackets. This reflects the Rega philosophy of low mass structures not retaining vibration whereas dense, heavy structures tend to retain energy and dissipate it slowly. Linn used to insist their Sondek should always be placed on a lightweight coffee table rather than a heavy (dense) piece of furniture for exactly the same reason. Seems counter - intuitive but very easy and free to try - what's to lose?
What I find to be the best way to isolate my Turntable was to fit a wall table to the wall of your home where you then won't have any contact with the rest of your home & these come with a 4 spike mounted plinth which is a great contribution to your HiFi set up when you can afford it.
Again, no spunges. Buy some mdf board, cut for free at home depot. Go 3 of 4 sheet thickness. Add 1/4" cork sheet in between the mdf. Use feet of your choice. Under 20dols. Also get the turntable away from the wall.
I've developed a rumble filter that beats anything. It is a four pole, two zero elliptic filter using two FDNRs (frequency dependent negative resistance) networks. It operates at line level (tape monitor or other 1Volt I/O. It is flat down to 20 Hz. Down 17dB @16Hz, down 30dB @7Hz. Believe me; there is no other like it. I've been using mine for 2 years with my Dual 1229 and it's remarkable. There is no audible difference between in and out except that the subsonic rumble is gone. My woofers love it. If you are interested in this 'final solution' to rumble, let me know.
I use the Ikea cutting boards under all of my turntables. However my boards are sitting on spring loaded isolation feet from Amazon, one under each corner, and I have no feedback problems at all, and I can literally jump up in down in front of the turntable with no skipping.
Brilliant! Anti rumble mats for washing machines are also worth playing around with - maybe as an inter-plinth to deaden the resonance of the plinths.
Bass loop was a real struggle for me! I just bought a subwoofer and I had to add some vibration solutions to my sub and turntable to fix the problem.
Not too bad but there are proven and professional solutions available (usually based on pneumatic suspension). Search for vibration isolation table in your local online auction provider (in the optics, medical & lab sections) . You can of course buy them new as wel if you have the 10...15k lying around.
The foam would eventually compress from the weight. Ideally it would be useful to add springs to offload the foam so it can retain the flex to absorb the vibration.
I recall, many years ago, before the days the internet was a thing, reading that the turntable should be placed as far as possible from the power transformer...
That is a excellent idea. I had a similar problem that has been going on for a while. Thanks to your sponge trick now I can enjoy my turntable at high volume so BIG THANK YOU
Just ordered the Ikea cutting board for my turntable and i am going to try the sponges underneath it,thanks a lot for the video.
Good idea. I had a similar problem with several turntables, not so much with rumble, but hearing noticeable distortion when playing loud. Tried all kinds of flexible rubbery footers (diy and commercially available), but they all degraded the sound in some manner. What finally solved the problem is 3 diy rollerblock footers made out of bamboo wood, spoons and 10mm steel or ceramic balls. No feedback, no distortion at any sound level, very natural sound.
Thanks for the tips so simple and so effective and not expensive
Love your channel and in awe at your electronic skills! Always mount a turntable on a wall shelf not a floor. Make a box as the shelf, about 10 cms deep, fill with dry sand and top with a glass panel floating on the sand. Level carefully and then place foam pads/another glass panel/turntable, level again as shown in the video.
Thanks for the cool tweak!!
An excellent suggestion! Thank you!
Nice channel, thanks for sharing your precious knowledge 👏🏻🙏🏼
Good simple solutions that work. Even the simplicity of the wood strip to hide the sponges is a neat idea that is 100% effective and costs peanuts.
Hi Gabby, really love your channel. I also have done some isolation for my 1980 Denon turntable. I used a different Ikea cutting board as I needed something near 19 in deep. I also used spring loaded feet under that and have been extremely happy with setup. I do not have a high end audio system, as I'm more mid fi.
