Support table or shelf for turntable


I was hoping to replace my oak table with either a wall mounted shelf of a heavy steel table.
The reason is that I am finding that the oak is picking up and transmitting vibrations to the turntable, a Garrard 401 in a birch ply plinth. I am hoping to move to a slate plinth and wanted to maximize the support strength and reduce feedback.
Here is a link to the shelf and here is a link to the table. Both examples of what I'm looking at.
Shelf would be mounted to concrete wall. Table would stand on concrete floor.
Thanks.

Is it OK for me to use Audiogon's (lame) policy to have posts removed that might expose one's truth?
@toddveronne,

Had several posts that were very enlightening removed.

Not because of profanity, not because of anything other that they exposed him for what he is.
@toddveronne,

Look at my partial inventory of used/ items/ I use on a regular basis on my profile that I added just for you.
@toddveronne,

I read in another thread that you have a tv screen in the middle of your speakers. Nuf' said!

I guess his next move will be to try and gain sympathy? Don't fall for it.
cd318,

My current view is a TT’s support system that can handle all of the earth’s forces and then, the room demands, the natural opposing forces within the room, the acoustic feedback is more important than the TT design. Frankly, how the room acoustics tame certain, mainly, low frequencies are of invaluable support to a TTs performance.

For if all of the above is addressed, most any TT will work well. There maybe a few acceptions.

To the OP, brick mortor, I assume is the same for cinder blocks...have contents that allow for ’movement’....IE: it is formulated to be somewhat flexible. Then I ask myself why? You could say to yourself, this is pretty 'extreme'? Just remember, TT's are very 'extremely' sensitive reproducers.

Happy Listening.
@cd318,

You had me until you recommended trying sorbothane. While it does damp vibrations, it is at the expense of dynamics and subtle cues and all of the little things that enhance one’s listening experience.

I was getting ready to post my current experience. As I stated earlier, I use a wall mount. Mine has several ways in which I can easily adjust it. This can be a nightmare or a listener’s friend. It all depends on how ’in tuner’ one is with what’s going on.

In my part of the country, I’m experiencing 25 degree temperature swings every day. This results in how I hear music and having to adjust my wall mount accordingly. My situation is extreme as opposed to the OP’s in that I have the 2"X6" wall construction, but I believe it should not be overlooked.

I meant to say that, as stated earlier, I'm on the east coast too. There are a few major fault lines running underneath us.

Do not discount the effect, seemingly unnoticeable changes to your (wall-mount) TT mount/support and how they can dramatically affect your listening experience!

@cd318,

Thanks for posting the link to the video I mentioned above. You make it So easy.

I only hope, everyone watches this!
Hmmmmm?

Decouple?

Sounds familiar?

Actually, I have two family members that have worked for/do work for NASA. This is not an issue. The issue seems to be those that purport to be experienced, having some influence on others!


@toddverrone,

While you're out "climbing/hiking" and such, I'm here listening.

That says a lot, doesn't it?
@toddveronne,

You, my friend, are what I see as the "worst" of what should be looked highly upon here!

I think about "newbies" looking at us. I think about people trying their best to get into this hobby, hoping for "sound' wisdom" from years-long posters.

Yet, you, undermine the very foundation of these principles!!

Shame on you!!!!



Taking you at your word "now"......

You "now" make a distinction... (this comes from my prying you to make some sort of meaning from your past posts)... of me being "confrontational", without your acknowledgement of any personal experience regarding your "recommendations" to others to how "their" systems should be. Yet, You now acknowledge you have no prior experience with wall mounts. But you recommended a wall mount. Right? Why? I would never recommend ANY product that I never used or had experience with.  You did. Why?

You now inject a  new (move), now to say you're getting ready to go out...

You now say "I'm being confrontational". Interesting? This was how I felt about your responses, a long time ago. Yet, I dealt with it.

You seem to have a "bag" of excuses to bring out when necessary?/

We are still waiting on your "previous posts regarding our recommendation of using a wall mount", and your experiences as such.

When you get back from your rock climbing, maybe you'll have thought of a good enough answer.

You now subscribe to my post regarding the expansion/contraction of walls...only after I posted it.

Be safe!
I think I’ve earned the right to ask, @toddverrone..where are your experiences regarding wall mount TT systems?

I asked this earlier.............. You tried to discredit me for my passion/knowledge in my posts.

Now, the shoe is on the other foot? When it was the other way, I responded.

Where are you?

Give me a break.
"East Coast- not many tremors!",

While I have an issue with that, as I live on the east coast and have experienced many, ..this is about more subtle vibrations that aren't readily noticed by us humans, but ARE by our beloved music transducers.

Good luck!
@toddverrone,

Apparently, most view me as "an a--’ anyway, so I have nothing to lose? If you are really being honest, you view me this way, so don’t try and say, some may view me this way in the future. When I post, I come from a position of confidence by way of my own personal issues that I’ve had ongoing and found effective ways of dealing with. Your position started from a point of view you chose not to be honest about. Get real, dude!

I think my passion is greater than most that would lead some as yourself to feel this way.

The fact is/was, you were never grateful, until I brought this fact up.

Let’s get to the topic at hand. Your post to noromance reads like you are an authority on wall mount systems? Are you? Have you ever used one? If so, what meaningful recommendations are/can you pass on to noromance?

Let’s start here, alright?
Look at the Townshend  youtube  video of how his product helped him win best of show under a speaker on a concrete floor.!!

Then think about a TT......a super-sensitive product that will pick up ANY abnormality.???
wolf_garcia,

This doesn’t mean there is no further upgrade path. It just means what you’ve done sounds better than what you previously had.

@ noromance,

With a wall shelf comes other problems/issues. I, myself use a wall mount system.

With the change in seasons comes contraction/expansion, so I would recommend you having a thoughtful way of leveling this system. It’s easy for anyone who hasn’t/doesn’t live with a wall mount to advocate for it and "they’re done".

My initial recommendation took into consideration your (self-made) table as a major factor in any recommendations.

@toddverrone ’s recommendations are a mix of what I recommended to him, (that he now uses) and what he has read, (that he does not currently use (to my knowledge). I think he thanked me by saying something like... "you need to either quit drinking or get laid" Is this the guy you want to guide you for any future upgrades??. Be careful/mindful of who you choose to deal with?

( Just because you don’t readily experience any "foot-fall" issues does not necessarily exempt you from being isolated from the earth’s crust movement...IE: the floor.) For me/in my world, this type of issue is what I refer to as addressing the "basics".

I’m out.

Good luck!


I can appreciate your current set-up.

Upon reconsideration, I believe you could now see improvements from a total isolation/sonic perspective? Right?

Good luck!
I double what geoffkait just said.

It depends on your approach and your budget.

If you are dead set on keeping what you have, here goes...

Invest in a slightly larger Maple platform of 3" thick and slightly wider than your current rack dimensions. Install (3) Brass feet (into) this platform. Then add another maple platform on top of that decoupled by load rated springs, (hopefully you have the ability to or will have someone line these platforms up and recess the springs by 1’8" inch into the bottom/top.

This will add 5"? to your current set-up? I assume this won’t matter since your components are already in the "line of fire", so to speak.

This will completely decouple your rack from the floor.

Now that your rack/system is decoupled from the floor...you can begin to address your components as geoffkait mentioned.

To mention your marble again.. most materials are not perfectly level. While it may seem the oak platform or the marble mates well, most likely there is a big void in how these items mate, (in audio isolation terms) that compounds the very problem you are trying to avoid. So, most of the time a ball bearing type of interface or a spike is the best way to transfer vibrations. Not always though.

The basics first, is the best approach.
Took a quick look, I find it fascinating that since you feel the oak is causing the "pick up" of vibrations that you use marble slabs under your TT footers?

In my experience this is a double negative. Marble adds mass but acts as a microphone.

What material isolates the oak shelf from the rack? What are you using as the rack legs interface to floor?
